Substance Painter to Roblox Studio UGC Item

Hello! Ive textured a model ive made with substance painter which I wish to make a UGC item. However to my understanding UGC items require you to only have 1 image texture. How would I go about combining Colour and normal maps into one? How do most UGC creators go about this importing their substance painter textures into roblox studio?

I think you can use ‘SurfaceAppearance’ to do this. It gives you extra fields to add Metalness, Normal, and roughness.

The problem is I dont think UGC items can use SurfaceAppearances they can only use a singular texture. So like importing from Substance painter is a hassle because it exports the texture in multiple file types which I dont know how to compile together.

I think what people do to bypass this is by uploading the hats as tshirts like this:

You might want to wait to upload it until ROBLOX’s new updates roll out later in 2025. Looks like PBR will soon come to accessories, which I think might fix your problem and then you can upload it as an actual accessory rather than layered clothing!
