Hi All,

I have a .OBJ and .3DS I tried different parsers of those files, and I call
numChildren and they always give a 0 output.

The .OBJ has 36 Materials, and 1 Mesh.  I tested also 36 Materials, and 36 Meshes.  Nothing worked.

How Do I change one material in a .obj file in run time ? A code hint would help

Attached the sample files

you have dedicated assets events you can listen to, to access a mesh. If the object that you test is a Mesh, and has no children, it of course returns zero numChildren.
Inspecting your model hierarchy into Prefab or AwayBuilder could also pin point you to some valuable information as well.

Yea but I do want to change the meshes’s texture at runtime too, not only at assestloader event listener, is that possible ?

Of course it’s possible, you simply save this mesh or its material.texture as class var or in a vector and reuse that later on.
