Hi;
I have been working on the Collada importer and exporter for quiet a long time now and added a few missing features like
- sampled animation exports
- skeletal animation exports as curves
- global axis transform upon export
- Fixes for old and long lasting bugs.
Now i am about done with the most part of it, so i guess its time to do some “real life” testing. And i am sure there is still a lot todo since i have only tested simple cases so far. Maybe you can find the time to do some more meaningful testing ?
The most complicated part of the thing is for sure the animation exporter and importer, so getting this tested in more depth would be awesome.
The most recent version of the Collada module is in master now and should be in the daily builds today or tomorrow. Any feedback is very appreciated. Please report failures even for the most simple tests. Those issues tend to be overlooked most 
Special note for Secondlife users
The Collada exporter for Blender 2.80 now can export Armatures which have been created in Blender’s native orientation (character looking towards negative Y) You would set the Global Orientation panel as follows:
- -X Forward (yes, minus is correct!)
- Z Up
- Apply Global Orientation (enabled)

Happy testing
