Description

We loose transparency when we convert .dae file to .glb.
It seems to be fixed #218 but the problem is still there.
We use v2.1.5.

Research direction

Reproduce the conversion using the attached test.zip with version 2.1.5, then compare the behavior with the change discussed in issue #218. Trace the COLLADA-to-glTF conversion path for material transparency and verify that the resulting .glb preserves the source alpha channel.
