[Bf-committers] Collada-patch for testing

[Gaia Clary]

Hi.
Should we fully switch discussion to the Wiki page ?
I answer here and add a comment to the Wiki as well.

I have contacted the Maya user for giving me some more help. 
Unfortunately he
is under pressure and can get to testing only in a few days. I tell you 
the results
as soon as i get them. In the mean time i try to get a Maya test license.

I do not understand what you have in mind here. Do you think about
an export option like:  "[ ] enable 90 degree rotation"
Probably it is best to first see if other programs need that rotation thing
and then decide if such an option is needed at all, or just the code fix
would be fine.

There is no scripting involved in the tests i made. The current state 
(with your patch):

export character only: Reimport to Blender results in 3 objects of size 0
export character+rig: Reimport to blender gives 3 objects of correct 
size plus an
armature with 90 degree rotation of each bone around z-axis

It would be a good starting point to see the exporter patch in trunk. I 
am sure as soon as
the patch is in Blender, there will be a lot of users going to test it.
