Textures failing to load

Im encountering an error, when exporting textured meshes onto roblox (from blender). As you can see below, there is a tree which I textured in substance painter. There are two materials in the object, for the bark and leaves.

Unfortunately, when I import it onto roblox, only one texture appears on the tree, even though they’ve both loaded (below).


What could be the issue?

The texture doesn’t carry out when you export. For simple objects with mainly just 2 colors, I recommend making two separate objects to export and coloring them as you like. I would then make it a union, but thats up to you.

Its one mesh, with two textures.
