Sprite3D how is the obj model mapping working ? how export from blender?

How do i map 3d model ? with simple UV mapping ? what is the limitations ?
when i import the boss.obj file into blender i don’t see any UV mapping.
do you use any other method for mapping 3d model ?

also when i Export mesh from blender to *.obj file it export with .mtl file
but i dont see in the Sprite3D any use done with this file.
how do the obj file save the UV info ?

I think we need some docs about Sprite3D and future plans. It´s a very powerful tool but I can see that nearly anybody knows how to use it.

If you use an obj you cannot run actions against it. Its to “fat”. I think that you also need to include the .mtl in your Resources. I need to double check that. mtl is a file that contains materials definitions.

use fbx-conv in tools to convert it from a .obj to a .c3b so you can run actions on your sprite

I have changed my .objs for .c3bs and the Sprite3D::create() method now returns a null object… going back to objs…

ok, since you and I are working on your other issue. I’ll try this too in my debugging.
