Buf.

I have tried to apply your solution, alied. But I couldn't.

There was no collada loader in the links you provided. Searching forums, I found this thread:

When I went to the project that is referenced in last post, 3dworkbench, I didn't found the loader (the post is 26th november 2009... maybe it's not deployed yet).

So, I tried the link in the first post, looking the loader from Shiva. This is the only loader I have found.

Down, there is a link to the jar version of the loader.

So I have downloaded that zip, put in classpath, set the windows registry
HKEY_USERS\...\Software\JavaSoft\Prefs\com\eteks\sweethome3d\j3d\additionalLoaderClasses=KmzLoader, and then go for some sketchup staff, export in kmz, and try to import to sweethome3d... but it says "format not recognized".

Obviously I'm so far away to know where I fail. I will try something, like calling the class with full name... but I will give up soon if I find no clues about what I'm doing bad.

Thanks for your help, if I have more information, I'll tell.
