In fact it seems I can´t get loaded or created alpha textures to work, although dds seems to work but not a bmp with the flags 2+512 (won´t mav like "2", but still doesn´t work, the object remains opaque, tho diffuse textures are applied correctly)
Other texture blendmodes work: blend 3, masked, as well as EntityAlpha and BrushAlpha.
