You are right it's something I have done ... didn't mean to offend by
not using code ...
It gave all false because I was being fancy with the traces doing:
trace("Is obj1mesh a mesh?"+obj1mesh is Mesh);
and should have been
trace("Is obj1mesh a mesh?"+(obj1mesh is Mesh));
Now I see the "parsing" ... thanks for help and the code which I will
impliment.
Any advice on getting texture swapping done on an .obj file?
tried:
for ( var j : Number = 0; j < obj1mesh.faces.length; j++ ) {
obj1mesh.faces[j].material = texture3;}
popped error on use:
TypeError: Error #1034: Type Coercion failed: cannot convert
Test67_texture3$ to away3d.materials.ITriangleMaterial.
for ( var j : Number = 0; j < obj1object3d.faces.length; j++ ) {
obj1object3d.faces[j].material = texture3;
}
failed on compile:
1119: Access of possibly undefined property faces through a reference
with static type away3d.core.base:Object3D.
