Collada export: Missing id attribute for visual scene node?

Hello, I just noticed that a Collada exported from 2.8 (9abcf56fa88) references in the instance_visual_scene node to the visual scene with the id “Scene” but the visual_scene itself does not set the id attribute.

I noticed this, since a game engine which seems to be very strict about this refuses to import the model from this Collada file.

I’m no expert about the Collada Scheme, but this appears to be very strange.

It’s best to report a bug in the tracker for this:
