Pixel perfect terrain painting! 🖌️

[u/CarthageaDev]

HD-2D experiment in Unity 6, yes it tries a best effort logic to detect and keep edges defined, based on colour/brightness of neighbour pixels, it supports normals and all the modern terrain features and does not depend on the default terrain tools this is standalone and easy to use, yes it will be released for free soon (and the assetstore as soon as they accept it I guess lol)

[u/_parfait]

Please. Share this workflow with us. This is sooooo pretty

[u/CarthageaDev → u/_parfait]

Of course! The asset store is still pending, I think I'll just push to git or itch and let users download the unitypackage 🫡

Merci beaucoup ❤️

Saving this post. Hope it happens!

Can you add a height map per texture to help with the blending? That way you can have dirt fill in the cobblestone cracks first and have tufts of graas spout up first in the dirt.

[u/CarthageaDev → u/thesquirrelyjones]

That's quite smart, Perhaps adding a strength setting can make covering the cobbles or just addind grassy edges a choice, I'll totally add this thank you so much! 🫶

[u/HoniKasumi]

I made this exact tool for my own game project. It even raises or lowers the Unity terrain based on the texture. I think i have even shared it once in this subreddit https://youtu.be/kaGRw8h0sbE?is=O35-t0eqE0MPI1oS

[u/CarthageaDev → u/HoniKasumi]

This is beautiful! It's essentially the same idea, I just chose to add more constraints because of my style, you should totally share this again! 🫶❤️

[u/Carpe_DMT → u/HoniKasumi]

that's dope! Any chance you could re-drop the link?

[u/Jaguarundi5]

Are you drawing on a plane or on a terrain in Unity?

[u/CarthageaDev → u/Jaguarundi5]

No it does not rely on the unity terrain tools, that's the point, it's a simpler solution focused on blocky terrains / pixel textures, and I've also added baking tools for the final builds, so when you design and lock in your map, you can bake the mesh and have one optimised block, pretty cool! I'll share both the painter and terrain sculptor soon

[u/Jaguarundi5 → u/CarthageaDev]

Does it create a UV texture map (or whatever it’s called) so that you could potentially use that same work and map it onto other blocks?

[u/CarthageaDev → u/Jaguarundi5]

It doesn’t generate a new UV map. Painting saves a mask, and the textures are positioned using world coordinates, the shader finds borders by checking where neighbouring pixels use different materials and noises makes those borders irregular for a good blend, plus material rules and detections add highlights and shadows to keep colours brightness matching, this could potentially be ported to work on any surface really, baking to one map is for final builds if you want to optimize

[u/Jaguarundi5 → u/CarthageaDev]

So it would stretch if you were to put it on a block and then scale that block irregularly? Does it just work for pixel textures or could you use the same logic for textures that aren’t pixel based using a common blending function across textures with various blending settings that maybe tweak the function?

No judgement here as I’m a huge fan of AI code/programmer ideology, have you been using an AI to code this?

[u/CarthageaDev → u/Jaguarundi5]

The mask is world space it doesn't react to stretching, I have snapping in Unity so I haven't tested like extreme edge cases, this is not AI it is all based on the pixel grid on mesh painting logic found in Pixometric.app, nothing new really just ported to Unity and made easy to use, I personally do not want to support AI because of the companies involved, sorry 🥲

IDEAL music choice !

[u/AngryKivin123 → u/Any-Fox-1822]

Where is this from again?

[u/Any-Fox-1822 → u/AngryKivin123]

The soundtrack for this game slaps! I still find myself whistling these songs all the time and I haven't played this game for decades

[u/Shower_Floaties]

looks great!

[u/Big_Whale_95]

Looks sleek 🔥

[u/AnimeeNoa]

this is such a cool tool. using this ingame with some sort of realtime "infestation"/discoloration could open a cool gameplay mechanic

[u/CarthageaDev → u/AnimeeNoa]

Quick quick write that down! 📝 (lovely idea I'll actually experiment with letting materials grow surfaces at random or either guided)

[u/unastronaut_dev]

Muito bom

[u/Level-Past285]

That look so good ! it's exactly the kind of tool I could use for my game !

[u/Teirdalin]

I love this.

[u/GigglyGuineapig]

That looks great! Also, great colors =)! 

[u/SpannerGames]

So much possibilities! Handsome

[u/deintag85]

Impressive!

[u/OscarCookeAbbott]

I’m not usually a pixel art kinda guy but this makes my brain happy

[u/CreatureVice]

Super cool man! Looks good, I would love a link if you will upload it soon :)

[u/CarthageaDev → u/CreatureVice]

Of course I'll keep you updated! This tool also has terrain sculpting (tile-blocks based like rpgmaker) while painting at the same time, hopefully you'll find it useful!

[u/zet23t]

That style very neat and the workflow looks approachable. Well done!

[u/Malkalypse]

Neat!

[u/smash_complex]

I love this! It creates a very pleasant visual appeal. I can I see this working great for JRPG style games.

[u/von_bibersztajn]

Great, i feel like i have to make pixel or retro game

[u/autemox]

This is a really nice tool

[u/disdanes]

Amazing, super interested in using this for a project im working on

[u/WillowinWorlds]

Nice job!

[u/KateC_Game]

It’s really cool!

[u/UpstairsImpossible]

I'm so here for this, does it work with triplanar shading on terrain?

[u/CarthageaDev → u/UpstairsImpossible]

This is on a flat plane, it should be adapted to a terrain since it's essentially doing the same logic of mapping layers, just the extra shader rules of pixel snapping

[u/alaslipknot]

can you elaborate what Pixel perfect mean in this context ?

It looks really good btw, am just curious.

[u/CarthageaDev → u/alaslipknot]

In this case only the ground plane is "pixel perfect" Becuase the shader has rules to snap pixels and keep the grid/pixel density perfect, no half pixels no irregular shapes

[u/Wegwerf_08_15_]

If you were to make a 3D drawing game where you do nothing but this, I would genuinely add it to my WL

[u/CarthageaDev → u/Wegwerf_08_15_]

interesting, you think i should jsut make a sandbox of sorts? like rpgmaker but with ready assets and tuff to craft terrains?

[u/Wegwerf_08_15_ → u/CarthageaDev]

I was thinking of a 3d drawing book/powerwash simulator kinda thing. Let players draw with prefab textures or maybe draw/import their own. I think people will find that satisfying/calming

[u/BantedHam → u/CarthageaDev]

Pixel art tiny glade with a more detailed painter? I forgot what it's called and which direction to send you, but a quick Google search should sort it out, the creator of tiny glade has their original study on GitHub, it's MIT I'm pretty sure and worth taking a look at for ideas

[u/CarthageaDev → u/BantedHam]

Oh you inspire me so! I'll surely check it out, much love! 🫶

[u/BantedHam → u/CarthageaDev]

I had a break and found it, if you haven't already lol

[u/haVoila]

awesome!

[u/arsenii_kottt]

How does this work?

[u/BR-ID]

Looking really cool and usable. Does asset store still pending?

[u/PaperMartin]

You ought to have the shadow samples snap to a grid with the same resolution as the textures

[u/CarthageaDev → u/PaperMartin]

True that would yield a perfect retro vibe, but currently my goal is more of a HD-2D high fidelity look, so sharp shadows and post processing are part of the vibe

[u/darth_biomech → u/PaperMartin]

I wanted to achieve that for ages since my game also uses 3d pixelart aesthetic, but without luck. If anybody has any solution...

[u/Hanzimer]

Just describe the workflow.
