Hi, since I installed Prefab2 new version (2.136), I can’t import awd2 models exported form this version. I explain it:
When I import the old model, cube.awd (exported with the previous version of Prefab). The model is loaded successfully.
But when I export the same model, wiht the new version . When I import it, wiht the same code of first; Flash fires this error:

“TypeError: Error #1034: Error de conversión forzada: no se puede convertir away3d.core.base::Geometry@10d071791 en away3d.materials.MaterialBase.
