Hi guys!
I’d like to import this model into Roblox Studio and add the materials:
Seems like the model is in one part though, which makes adding materials to different parts kind of hard. Is there a workaround for this?
split this model into multiple models by material using 3d editing software.
Thanks! When I import it to Blender (or Roblox) the materials are not included. They are separate and I can’t figure out which of them goes where.
Well… when you import model to blender there will be one instance “Rugs” with three materials:
- Car
- Decoration
- Tanks
In edit mode select faces by this materials and separate.
Another problem: the materials are “empty”
When color/roughness/normal/metalness channels have image textures assigned Roblox creates SurfaceAppearance “automatically”.
Let’s create them then.
The file goes with tga textures, naming is pretty much straightforward:
Pose_MATERIALNAME_CHANNEL
Another thing is packing OcclusionRoughnessMetallic (three channels) into one RGB image.
So to be correctly imported it must separated to three images:
- mix Occlusion with BaseColor and set to material color
- Roughness and Metallic go to corresponding channels
After these done you can export fbx and import it to Roblox.
Roblox warns about tga import and suggests to use png
I skipped OcclusionRoughnessMetallic and conversion to png,
it’s kind of better than nothing especially that it shows that approach is correct
final appearance should be different if everything is done correctly
I already had converted them to .png. I managed to separate the model into threee parts. I split the ORM into three in PS and then added AO and BaseColor together. In Roblox I made three Material Variants with names corresponnding to Car, Decoration and Tanks. When I add them in Roblox they don’t add correctly and look like a mess 
well, i see two problems here:
- uv maping is incorrect, does your model look correct in blender with shading enabled so you can see textures?
- white meshes, do they have surface appearances with assigned textures? also i forgot to tell that i have removed not used materials from models so each model contains exactly one material; also have you seen any errors during import?
