Description

Blender Collada exports transparency information but does not import it back

Event Timeline

The Collada exporter now exports Alpha by using the <transparent> tag instead of <transparency>. On the importer side we have added support for both tags in accordance to the Collada specification, see chapter 7 (handling transparent and transparency):

The good news is that the exporter now can determine if a material has transparency enabled even when Alpha=1.0 . Before there was a small uncertainty about whether the material has no transparency or transparency with alpha=1.0
