Hi, I have problem with adding occlusion to material.
This is augmented reality project with face tracking. You can try on earrings.
Problem is with head object - in reality when you turn your face, one from earring is covered.
So for this case I use material occlusion attached to head mesh, but it dosent work :(
In onPostacComplete2 function I try do it - next step was adding alpha to head mesh. And then somthing is crash with background scene - is black (all object are including to contener3d object in away builder - it dosent open i prefabs now). Next problem I think is that something is wrong with this function :(
Maybe somebody have better solution for this case? See picture from application - it will be easier to understand my problem.

{
var glowa_mat:OcclusionMaterial = new OcclusionMaterial();
glowa_mat = OcclusionMaterial(AssetLibrary.getAsset('glowa'));
glowa_mat.occlude = true;
}
Structure awd is >Container1>head_mesh
and head_mesh have material name ‘glowa’
