Custom Grass Terrain Material Override not Working

[Reditect]

Visual Aids & Explaination:

In my current version of Studio, my custom grass material isn’t working as it previously did. I’ve included (in the Private message for Staff) my current project version (where the issue is happening) and a version from 1/9/2025 (where the issue is not happening).

The MaterialVarient and TerrainDetails are the same in both versions. The ColorMap, RoughnessMap, and NormalMap are also the exact same. The Material Overrides under Material Service for Grass is correctly set to the CutstomGrassMaterial. This is where the Material can be found in the Explorer:

To see the issue for yourself, open the attached files of my project. Notice that The one from 1/9/2025 has a material that works perfectly fine:

My current version of the project, also attached, looks like this:

If you need more info, please let me know.

Expected behavior

I expect my grass material to look like the one from 1/9/2025.

Thank you for your report. Could you double check they both have the same LightingStyle under Lighting?

Could you double check they both have the same LightingStyle under Lighting?

It turns out they had a different LightingStyle, but this didn’t happen when I first changed LightingStyle on the 21st of January. Is this issue of textures not working the same intentional?

When the Unified Lighting Update happened, I said this:

@Reditect

I opened Roblox Studio just now to check my lighting and it changed drastically. If I wasn’t a devforum addict I probably wouldn’t understand why things looked so different. I used ShadowMap lighting for the “soft” look. My lighting was changed to Realistic with PrioritizeLightingQuality off. This is what it looked like when I opened studio:

I fixed it to look the same by putting it to Soft with PrioritizeLightingQuality on. This is what it looks like now:

The issue (seperate from THIS thread issue) is described better here:

@ItsRainingPixels

Your previous Technology setting will automatically map to the above configurations to maintain consistency

This does not seem to be the case. Whenever I open a place that previously used ShadowMap, the LightingStyle is always set to Realistic, when it should be Soft instead, and I have to manually change it.

@ItsRainingPixels

• Future: LightingStyle = Realistic & PrioritizeLightingQuality = Enabled
• ShadowMap: Lighting Style = Soft & PrioritizeLightingQuality = Enabled
• Voxel: LightingStyle = Soft & PrioritizeLightingQuality = Disabled

Now, on January 21st when I opened my Project, no matter the LightingStyle, I believe the Terrain looked the exact same. My project before the Unified Lighting Update was ShadowMap. My Terrain looked fine then too. Why would the Terrain look different now if I set the things to match ShadowMap?

I think someone is having the same issue here:

@Dj_Sorcha

Is Lighting Style Suppose to be Connected to whether or not Smooth Terrain has Blending or is it a bug? If it’s not It really should be another setting developers have to choose from instead of forcing one or the other.

Example

Style: Soft

Style: Realistic
