Hmm, interesting. I didn’t even realize the material replacements even worked with terrain materials, maybe the coloring is something they’ll change before the release.
In the OP example screenshots, they didn’t change the cobblestone or grass terrain materials in the before/after shots.
If you try replacing a different material does it make any difference in the tint of your replaced material? Like, replacing ice vs asphalt.
What i think would be awesome would be that ability to create new Material overrides. For example i would like to have Leaves or Dirt and instead of overriding Foil or Pebble to suit my needs i could create a new Override to allow them to be used with the part or allow me to have multiple Bricks for different style homes etc.
Thanks, I’ve been looking forward to this! I’ll let you know if I find any issues.
An awesome beta feature! Can’t wait for the full release. 
Would it be possible to add the ability to blend materials, as it does on Smooth Terrain, on MeshParts?
It’d be super-duper cool if we’d be able to paint multiple MaterialVariants over MeshParts as well with the blending!
how did you apply a custom material to terrain?
Good question, i will try it as soon as possible. Note I already did a test with the Sand material and it worked out fine
Just tried it, no effect. Thanks though
One thing I think most people haven’t thought about though is why hasn’t Snowterrain became a material yet? I’m begging for it to be added into the basic materials roster and been wanting the snow material to be used for parts.
I had these done as a test for custom materials, but thanks for the feedback…? I’ll look into improving them for the future at some point.
When can we expect custom materials to work in Play mode?
We have no date to share right now, as we want the flexibility to change this feature based on feedback during the beta process. Don’t worry–we recognize you all are excited to use this feature in your published places, and we’re excited to see how you leverage it. We’re pushing hard to get this usable in production experiences!
What I would be interested to see is the ability to not only create new terrain materials, but to be able to define what mesh it uses. I know using a user created mesh could have it’s fair share of issues but to be able to use the shapes that the built in materials already use. For example, you have rock, wood planks and grass that use different shapes to form the terrain. Imagine being able to use the same shape as wood planks (blocky shape) to create voxel like terrain. Would be cool to have different shapes of terrain. Even if using a mesh for each material could be costly, you could also do like a general terrain shape rather than specific shape for each material. Terrain is the closest we have to mesh creation. Seeing Triangle shaped terrain would be nice for creating more complex and crazy terrain as well. It could expand how to customize the terrain in the future!
I cant wait for this i wish to be given a date when you can, looking good so far
But first they need to fix the ofset issue 
are they even going to fix it? or i am waiting for nothing lol
Of course they’ll fix it before the full release
i made a game with it and now i have to wait lol
Thank you for the response, I’m so excited for it to be usable in production, can’t stress enough how much time this will save not having to UVMAP every single mesh, let alone not having to worry about UV textures stretching for certain modular assets
I have a big project in the works, that should be shipping around April, but I’m concerned to use custom materials when there’s no exact release date, which sucks because now I have to go forward with the UVmapping process incase this doesn’t ship in time with the release of my project (otherwise there would be no materials in play mode)
I’m hopping this releases as soon as possible. So far from my experience it works solid!
Do you know when these will start showing in game?
Yeah! I can finally change the terrain materials. Any info about public release to games? This’ll really help in development.
This is probably going to be one of my favorite Roblox updates 
creates so many potential ideas for environments!
