Vanra oh, totally forgot about them. I think they will be blacklisted for now, because fixing them and other similar blocks is not an easy task

ZeroAresIV should be fixed in the latest versions

BeloMaximka im mostly refering to the fact that when a grassy block generates on a hill it looks off. Not to mention when blocks like forest floor or Clay in Soil it squishes the texture as opposed to just getting half of the block texture. Essentially causing mixels and looking very off.

BeloMaximka, Vanra : Thank you very much!

There is an isse with fences on slabs. Initially fence you can post on slab BUT any further will disconnect looking for full block.

RahRabbit Majority of mods compatible with 1.21.0 will work without any issues with 1.21.5 - majority. Advice getting https://news.kalataka.ru/vslauncher make second instance of game with 1.21.5 coppy mods via folders %appdata% and do quick test. Im running 1.2.5 with 20(?) mods that are set to 1.21.0 without any issues (and 150 others including some from 1.20.x)

Hm, turns out it is compatible with 1.21.0+...
Let me bump the version

Hello. I'm new to VS, so I'm not sure if this kind of query is disallowed: is there a chance of making this mod compatible with 1.21.0?

I've using several mods that won't reach 1.21.5. (or even 1.21.1 for that matter). Being able to just walk around sound like such a wonderful idea...

Hearing good things about this mod. Like someone else said, I'm letting it cook for a little bit but am very, very interested.

cadavr yeah selection has some problems and I will try to fix it in the near future

As a casual player, I've been playing for a few hours and a couple different map generations. This works pretty solid and has improved my experience quite a bit! If there's anything to point out is that grass and low height objects like stone, bowls, etc are sometimes hard to target at certain angles (like theres a deadspot while trying to target something thats on a slab unless you are directly above it). This isnt too much of a problem unless I'm trying to cut grass that's going up a hill effeciently or something but I thought I would point it out for finetuning. The instability + this mod makes collapses more immersive for some reason. I'm also playing with lots of other mods as well including Terra Prety and other worldgen mods with this working just fine. Again I'm not a hardcore player of the game, but this is pretty darn solid to add some granularity to the world.

1 step closer to better than wolves.

no way, this is awesome wow

yes, dirt/sand/gravel instability is supported, cave ins as well

will the dirt slabs be affected by gravity if dirt instability is on?

For what it's worth, I'm very interested in this mod, I just like to wait a while on new mods to give them some time to cook so I don't have to download a new update every day.
And this mod seems like it would be really complicated and important to iron out, so I'm planning on waiting an extra long time unless I know it's pretty much ready.

ZeroAresIV you mean the small dirt gap?

sadly makes grassy blocks look weird as it doesnt spread below, 

And another one lol

This is the last one I promise, at least for today :)

Wanted to just fix some minor stuff and completed the whole backlog instead

Now I need to spread some slaboganda to see if this a coverage thing or this mod is really just for a small group of madlads

Ty all for testing and feeback! Place your chests, cook your food and knap your tools on slabs and let me know of any new issues)

An update already?! Wow this mod is moving faster then I thought it would! Keep up the great work!

Great, but hurry up because I need to open a server lol
Just kidding, take your time.

Limbobinho ok, found the issue. Thanks for your report! Some issues with vanilla rendering, will be fixed in the next mod update

I was messing with conquest landform and making some worlds, when I added this mod it made generation and chunk loading so much faster and smoother. I have no clue why, but cool mod!

Sorry for the delay, here's the video and the log with the mods.
https://drive.google.com/file/d/1ilLIi_uZiRQ4DhNK3f3cktn-NPv35Kmi/view?usp=sharing

Should be compatible with all worldgen mods that dont add new block to the terrain

So real quick, Wanted to check if this mod is compatible with Terra Pretty potentially. I have the coastlines one because I love the way it generates more proper continents and oceans and such. Having this would be a godsend and remove the need for the stepup mod I have installed. Hopefully my space bar can finally have a break!

NisplayDame hi, I am considering moving slab placement feature to a separate mod, but I need to make it compatible with most blocks and, most importantly, figure out how to make this logic automatically/effortlessly apply to any slabs. I want to switch to other mods before that so I'll probably start at the end of December or later

What's currently on my mind:

• offsetting solid blocks - against it, because it will introduce a lot of problems and be achieved already via chiseling
• offsetting other slabs/stairs - again can be achieved via chiseling
• non-chiselable blocks like chests/firepits that occupy 1 block - yes
• blocks that occupy more than 1 block like doors/beds - I think they will be blacklisted because then the game has to keep all parts synced which is a lot of work. Also performance risks. BUT it is possible, so my mind may change
• gears, chutes, other stuff that connect - blacklisted for obvious reasons

Diving deep into the engine is not a problem tbh, I just have a limited free time :)

BeloMaximka Hi, just wanted to say - amazing mod, adding slabs to worldgen can make huge difference

I also want to ask, is there soe hope that eventually you can make the base feature that any stuff(including modded) or even other slabs or whole blocks can be placed on any slab(also including modded), or that would be too troublesome since you would need to dive too deep into engine itself? Even partially that would benefit building designs by a lot 

DatVegan falling blocks on existing worlds are fixed in 0.1.1, as for Under Tangled Bough, you can just add the wildcard and it will match all blocks from the mod

"undertangledboughs:*"

Or just wait for an update, it will be released soon (I was carried away bugfixing and adding support for chests, firepits and other blocks)

Hey thanks for letting me know how to add compat. But I'm still a little unsure: should I add this for all blocks added by Under Tangled Boughs? Because I checked it, and since it adds different blocks facing eacht direction (n/e/s/w), it boils down to hundreds of blocks. So I'll wait for the update on it! While I think it's great you included a way to update worlds into slab worlds, I'd recommend people to start a new one, since the resulting falling blocks, cave ins and changed landscapes can be laggy and look quite ugly. 

1. 1.21.5
2. Latest
3. A Lot, I can make a list for you.
4. Singleplayer and dedicated
5. High

I'll make a video soon.

Limbobinho Thanks for reporting! Unfortunately, I can't reproduce this on my end. Can you provide more info please?
1. What's your game version?

2. What's the version of the mod?

3. What mods are you using?

4. Are you in singleplayer or on a dedicated server?

5. What's you graphics settings?

A video showcase could be really helpful as well

I'm seeing this bug. When I'm in Survival mode, on top of snow on a slab block, this happens.

Spoiler!

Damonicus1986 Vanra maybe I can add compatibility for these mods, we'll see

one thing i noticed on those half blocks if you play with natural trails mod the grass will never change will always be green doesnt matter how much walking you do over it :D

I been testing it out on my old world without "fixing" old chunks... man I love it so much! World looks so great... only gripe I have is that I got used to Climbing mod by Salty and you cannot climb on slabs 😖 I know its not your problem, but the world looks so much better I really considering dropping Saltys mod just to fully enjoy your work! Amazing!

Darthzz thanks! glad you're enjoing it :)

NisplayDame if the crash is not reproducible, it is probably something related to vanilla https://github.com/anegostudios/VintageStory-Issues/issues/6758

Bed and other multi-part blocks will be added to blacklist in the next update. Thanks for noticing!

Been playing around with this mod for a bit, one of the coolest mods I've seen so far and surprisingly compatible with a lot of things.

In creative, I placed some rock(conglomerate?) slab from mod and tried to place an (steel?)anvil at an angle

Also not related, multi-block furniture (like beds) behave finicky when you destroy modded slabs underneath (half of it which was under destroyed slab moves up)

NisplayDame can you please attach a crashlog and share steps to reproduce the crash?

Hi, while I was testing my game crashed when I was trying to place an anvil on modded slab. Also I would like to be able to place stuff on other ordinary slabs if that possible 

I think I will remove beta label in an update or two. I just needed someone to test it, and looks like there're no major issues. I made a lot of harmony patches and injections in rendering pipeline, so I was a bit afraid)

ArmoredStone

I think the '[Beta]' in the title is scaring people off. I tried to get peckCuss to try it out, but as soon as they saw the '[beta]' they passed. I'm very sure people will know what they are getting themselves into just by the version number. No need to scare them off in the title. But that's just what I think & I have been wrong before.

DecaByte probably human error. I'll double check the values and fix them if they're off. Thanks!

Strikes me as very odd that this mod doesnt have thousands of downloads already. I'm guessing more people havent heard of it

BeloMaximka 

When using this mod it felt like things were sliding a bit more. Looked at your fallingblocks.json & found "fallSidewaysChance" was at 0.75. From what I know that default is 0.3. It there a reson you have it set to 0.75?

This is my dream mod, I know it's kind of an heresy but I really think it should be part of the Vanilla experience because smoother terrain will become more and mode important with mounts and vehicles progressively added.

Currently if feels very unatural to see mobs, elks and large entities (such as carts in Cartwright´s Caravan) constantly jump 1m over and over. I'm working on a mod to change mobility mechanics in the game and I would like to add "roman stlye" high-end roads that greatly improve mobility at the cost of requiring a smooth trajectory (two low-angle road slabs instead of the usual 45° path stairs block) and it would beautifully blend into a smoother world.

I also think that what's limiting the addition of large entities in the game IS the fact that terrain vary by 1m increments. Adding large entities to the game presents a choice: let them make strange, supernatural 1-meter jumps OR condemn them to converge toward the local lowest point on the map (since they can only fall lower).

I play with Fauna mods and while it adds a lot of immersion, watching gigantic mammoth jumping higher and higher on tiny blocks along mountain cliffs is both hilaious and immersion-breaking. With smoother terrain it should be possible to nerf large entities (Mammoth, carts, wagons etc...) to being only able to move over 0.5m transitions.

I'm definitely going to follow the updates of this mod. I've tried it on a new save with the Terra Prety terrain generation and it really adds something.

Considering how detailed the story structures are, it's weirder for the world generation to still be stuck with full blocks only. So bless you OP!

JackRob glad you're enjoing it. I totally forgot about this bug, it appeared after some refactoring and I need to fix it in next update

MrFastZombie I tried to make new modded blocks automatically compatible as much as I could. Please  let me know if you find any isses with modded grass

How does this work with modded grasses (for example: Wild Grass)? Would it need a patch to offset them?

This has made my dream.  Saying that I love this would be an understatement.  Thank You.

Walking around in my world, one little thing I've noticed so far is that the slab for forest floor has vertically squashed side textures.  There are some that are a little grassier than others where this grassy part looks fine (likely an overlay), but the dirt below it is squashed.

DatVegan no need to choose, you can keep both!

Add them to blacklist using /ts b a undertangledboughs:* and they will be fixed after some time

But slabs under them will remain... You can run /ts us c 500 and /ts s c 500 to fix blocks in loaded chunks. Make sure to use 0.1.1 version so your unstable soil and sand won't go crazy

They will be included in default blacklist in the next update.

I need to completely rewrite config system in my mod so it can be more user friendly, but I need to fix severe memory leaks in ImGui wrapper by Maltiez first so I won't suffer using it

And by the way, huge thanks for reporting the issue!

I am testing it right  now and it feels lovely! There is a slight incompatability with Under Tangled Boughs, seems as though the tree stumps can handle being on a half slab, but the half block difference is see through. Does this also occur in vanilla tree generation? Because I cannot place normal logs on half slabs, but the stumps can be placed on half slabs.
Not even close which mod I would rather use, but the extra flavor of tree stumps was nice...

That should be in vanilla. Why we are not funding it?

My spacebar is tired of all these jumping, even on relatively flat terrain.

I didn't have any plans to gather money from modding, but can make ko-fi or patreon page later :) (need to figure them out first)

As for mod support from me, it initially was just a fun engineering challenge and a silly mod to keep in my singleplayer worlds, but seeing the community reaction, I will focus more on polishing it. 

Keep in mind that I have a full time job and a uni, so it may take some time. But you've played Vintage Story enough to have patience :)

Thanks you all for the warm welcome!

I have to say this mod is very impresive & really should be part of vanilla! Makes the game look a whole lot better! I hope this mod is supported for a long time as I see it being one of those mods that I can't live without.
Speaking about supporting this mod & modder. Any place we can donate to you?

DatVegan enjoy :)

DecaByte proportions in recipes are correct, pattern for block -> slab is 2 width wide in case some mod adds a shapeless recipe where you put 1 block in the grid. It does not apply for slabs so I did a 1-1 recipe for them. Not a big deal tbh

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!

My prayers into the void have been answered!! Immersion manifest!

Maybe this was done for a reason, I dont know. I notice on the block to slab crafting recipe only works with 2 or more blocks, it's '2 blocks = 2 slabs'. The Slab to Block recipe is right with 1 slab = 1 block.

DecaByte thanks for noticing, let's treat farmland as expected for now as I'd have to deal with waterlogged crops

Tilling the soil slab with a hoe changes it to a whole farmland block.

BeloMaximka

Thank you for your response.

Im sorry. I may have mis-comuicated what I was asking. I have dyslexcia & I'm not clear as to what I mean sometimes when I type. Ill try to shorten it to bullet pionts.
1. I would like to dig & pick up dirt & other slabs to be placed in my inventory if possible.
2. Would like a way in the crafting grid to merge 2 slabs into 1 block.
Sorry if i wasn't clear before.

Loving the mod btw. Already added it to my SP world.

DecaByte the issue with instability will be fixed in code in the next update. The mod will temporarily set the worldconfig to "false" during command execution and then revert to original value. Thanks for noticing
You can craft slabs in bulk if you wish to use them. I will also add recipes to Quality of Building (my another underbaked mod) so you don't have to fiddle with crafting grid.

Haven't tested with trailmod, but probably not out of the box, need to confirm. Compatibility patch will be a low priority at the moment bcause I will be probably busy fixing/improving other stuff

BeloMaximka
Id it possible to have it not convert slabs to whole blocks when dug up? I don't mind picking up slabs as I plan to make and use them. Also a way to make whole blocks out of 2 slabs would be nice.
Also is it compatable with trail mod updated?   
https://news.kalataka.ru/trailmodupdated

BeloMaximka
Might want to add this tip adding this mod midsave to a world with sliding blocks.
This will prevent blocks on steep hills & caves from sliding/falling while converting the world.
Load world, enter command '/worldconfig allowfallingblocks false' then exit & restart world. Enter command '/ts s c 1000'  fly around in areas you have previously load & run the command as needed. Once you feel you have converted all the blocks, enter command '/worldconfig allowfallingblocks true' then exit & restart world.
If removing this mod midsave from sliding blocks world, use the same /worldconfig commands with the 'existing saves' commands to remove mod. 

EthelVril the one i use is not the OG rivers mod but even when i did i never had any issues. i use rivergen because i like it better. and in my opinion terra is better for continants 

Damage_Zedd oh I thought terra prety was incompatible with rivers mod, is it better than conquest landform mod?

EthelVril i am using it with conquest blocklayer overhaul, terra prety and rivergen with no issues. works really well

Does this work with conquest landform overhaul and rivers mods?

Whats funny I was looking for dirt slab mod just the other day! Now here it is!

Liking this for the most part, BeloMaximka, but noticing that it causes the second level of stacks of firebricks to float above the first level.

I see. Well that is fine then.   
Stll great mod & will be adding it to may game. Thanks! Can't wait to see what you come out with next!

DecaByte the issue with medium fertility soil is vanilla behavior, this mod replaces existing blocks 1-to-1, (expect beaches, where it adds blocks to sides)

Configuration can be improved, yes

BeloMaximka
Only issue I found so far. Medium fertility soil (Grassy) slabs generating on top of low fertility dirt blocks in some areas. Seems to happen if there is some medium fertility soil blocks near by.
If possible add a config to disable the texture pack to help people that dont know how to edit mods manually.. 

I dreamed of such a mod and now it's here

it's finally here

Amazing mod! 

Very interusting. Ill give it a shot. I like where this mod is going!

I really love this mod))
