this a tutorial on how to fix a basic texture painting bug, i had one before but it got deleted so this is a re-write. i won’t be going over the basics of image painting.
when you try to import a mesh with a texture paint material, this happens:
you’ll need to save the image in the same directory as the mesh.
1- create a new folder just around anywhere. make sure you keep your .fbx in it
2- go to Texture Paint > Image > Save As to your folder

3- select the textured mesh and export as FBX. change the path mode to “Copy” and tick “Embed Textures”

this will create a .fbm folder for your mesh once you import it over to studio.
4- done
