How do I have the texture show up on my Blender model in Roblox?

I’m new to Blender and importing 3D models into Roblox.

The design I made has multiple parts and a texture image. I’ve looked through past posts but haven’t found a solution that works for me.

When I import the model into Roblox, I put the UV map under the Texture ID, though I’m not sure if that was necessary.

If anyone could provide guidance on the proper way to import a multi-part, textured model, I would really appreciate it!
