1. I made a cube with 6 plane faces in blender ( all planes were UV unwrapped) and exported, Diffuse map set with transparent color, draw side is set to both, and set the transparency to on for the Q3DModel...However only 4 faces appear transparent...One side face is completely opaque, one side face shows through back side planes but doesnt show through bottom face and adjacent face! Not sure if this is a bug or I am doing something wrong...
2. In Safari and Firefox, all the Q3D objects are inverted wrt Chrome
