displaying a jit.gl.model with the drawobject jit.gl.sketch message

Hello all,

As the title explains, I'm trying to display a 3D (.obj file) model using a named jit.gl.model object and sending the drawobject message to a jit.gl.sketch object.

That works, but I have strange depth displaying issues with the back and front polygons (I'm using the simple .obj models in the "media" Max5 folder), and I can't manage to find the right settings for the objects I'm using, or whatever the solution should be ...

Thanks for helping ...

Joseph
