Hi, I'm working on a Collada Export for a specific 3D tool and finally got my Java code right using JAXB and a lot of manual glue code.

Unfortunatly Blender3D loads my .DAE but doesn't display anything (no not a camera problem, as it's not increasing the verts counter). But the Collada test suite says all is ok?

Might anybody with more experience please help?
Maybe this simple box example of my output is helpful to you:
