[Bf-committers] Collada status

[Tim Knip]

Hi all,

FCOLLADA / COLLADA_DOM  would be ideal as that's what MAX / Maya are using.
Not sure on licensing and stuff, but don't expect much problems there
(COLLADA_DOM is hosted @ sourceforge).

But indeed: no Python bindings.

As I'm a Blender-noob: is Python 'needed'? Or could we compile C/C++
stuff in 'directly'?
And assuming we would go for Python, how difficult would it be to
create the bindings ourselfs?

Now: I would be inclined to take this on me, but you may understand I
need lots of help on the Blender API side.
Also, got a 'normal' daytime job, so things will take time.

IRC meeting: anytime... I'm in The Netherlands.

Tim
