Collada Support for Maya exports

darkfrog · February 11, 2007, 9:14pm

Okay, I figured the best way to get this solved was to drop a basic model that displays the problem hoping someone with more knowledge about the ColladaImporter can resolve this issue for me or give me some insights as to what is going on so I can resolve the issue myself. I get an exception like this:

This is the output from ModelLoader when I try to load a ship model that has been exported from Maya to Collada (there are a few others that get the exact same exception).

The example Collada file I'm posting here doesn't actually output any exception:

Unfortunately nothing displays either. I've included the the Collada file and the texture below:

http://galaxiesbeyond.com/download/MOON.JPG
http://galaxiesbeyond.com/download/Moon1.dae

These models work fine in FeelingViewer and I'm using the official Collada exporter from Feeling Software for Maya.

mojomonk · February 11, 2007, 10:34pm

I'm working on COLLADA at work for some other features. I'll take a look at the moon.dae file sometime in the next couple of days.

darkfrog · February 12, 2007, 12:01am

Great, I've got the final ship models for Galaxies Beyond and these problems are the only things holding me back from being able to use them in the game…sorry if I'm a little too eager to get it working.

Hopefully I'll be able to start posting some official screenshots after these model problems are resolved.

renanse · February 12, 2007, 3:22am

Seems like your collada file uses the polylist tag, I'm not sure we support that currently.

mojomonk · February 12, 2007, 5:13am

Exactly right, only <triangles> are supported. Which explains the moon problem.

darkfrog · February 12, 2007, 2:15pm

Crap…okay, back to see if Maya has an option to export with triangles.

mojomonk · February 12, 2007, 3:03pm

Josh just mentioned that Mr. Coder did add a support for polylist… but I won't be the one supporting that. If he happens to see this, maybe he'll give insight.

renanse · February 12, 2007, 3:06pm

Sorry for the misunderstand… he did polygons actually, not polylist.

mojomonk · February 12, 2007, 3:07pm

ok

You guys just like to play with my emotions..... :'(

mojomonk · February 12, 2007, 7:12pm

Collada is an open, well defined spec whose schema is easily available on the web… your destiny is in your hands.
