I made this gun on blender and baked the texture, i published the texture onto roblox as a decal and then tried placing the texture on the gun but it dosen’t appears as it should be.
If you made the texture, go to the the first part of Blender which I believe it’s called Layout and then what you are going to do is press Z and select Material preview.
If you’re seeing the texture with Material Preview, export the mesh as FBX and in Roblox Studio, export in assets management in the bulk button. Import all, insert with location and there
