Hmm.
This hack work, true.
I’ve try to change/destroy all the transparent/transparency attribute I could on the dae but with no change on the resulting egg
I hope you can find a solution !
We had trouble with these files ( created by the collada plugins for maya) before :
we can’t referenced the node in these files from scene in another file, like we suppose to do ( and like we do with other collada files)
So the problem may be with the exporters plugin, I don’t know
good luck !
