For the COLLADA community Blender is definitely one of the most important stakeholders to stop supporting COLLADA would make things in DCC exchange even worse.

I agree. Not to mention all those who co use it alongside LW , all of DAZ products....etc.

I actually tried to avoid a discussion here since a long time, but topic is too important.

First, kicking out collada from blender doesn't help anyone. None of the "common" interexchange formats is that reliable / support all features. To have at least a second format as a backup strategy,  if a certain features arent't supported / have some unreliable results, is a "must have" in every cross application enviroment.

Its frustrating that a lot of this discussion seems to revolve around possible solutions for _other_ people to work on which blender _should_ support. We already tried to support collada and pretty much failed by the looks of it.

Kicking out collada helps because it means we don't give users a barely working feature they report bugs about that we can't fix. It helps not to give users crappy software. no?

It also helps to move into a branch that motivated people can work on - so this feature can reach some level of quality before moving back into trunk.

And btw, blenders FBX import is, from my experience, still not as reliable as it should be, to actually replace collada. (sorry, this is no actual bashing... its already great what has been archived... especially if you consider that it is allways pain in the ass, to support such a complex exchange format)

again, would be nice to hear some example, even anecdotal as to what isn't working in FBX (assume you mean exporter since we don't have a stable importer).

We are currently discussing further financing of OpenCOLLADA and will spend more time the next months on bugfixing and conformance tests.

Sorry to say this, but this is one of the mayor reasons I have to post this:

Conformance tests do only help a little to 0 The big _advantage_ fbx has, is a working reference application called maya.

FBX was written for Kaydara Motionbuilder, which I used as a reference, Maya support was added later and it still doesn't support all Motionbuilder's rigging options last I tested. There are files written out of blender which work in Motionbuilder and not correctly in Maya.

No conformance test can actually be that foolproof to support all features and variations. So by this simple unoffical agreement,"if it doesn't work in maya - it is broken", users and developers have an ideal platform to discuss errors / find workarounds.  This greatly avoids the "picking in the dark" situation all developers currently face with collada. Even if a dev doesn't have access to it, in a lot of cases, he can track down problems reported by users who do provide a simple screenshot.

Could this collada reference application be Blender ? For me this is a very attractive idea, but also, I'm very aware of the fact, that I'm opening a can of worms I'm actually in no way in the right position to touch.

its possible, but at some point we need to follow a spec that works elsewhere for it to be useful. Otherwise having overly specific blender/collada format runs the risk of nobody adopting it and looses a lot of blender developer time.

Anyway just my 2 cents on this. chris
