sorry for the long delay, there was just to many things going on. I started working on a COLLADA_DOM based version. So far I got it to load simple geometry and effects (no shaders so far). But the biggest catch is I wrote it against 2.x. I'll see if I can get it over to 1.x easily. Currently it is available from the 2.x svn repository if you want to have a look (Source/System/FileIO/Collada). What I'm currently looking for is sample data, so if anybody has some collada sample files which you can share I'm happy to use them and improve the importer. kind regards, gerrit ------------------------------------------------------------------------- Using Tomcat but need to do more?
