Hi, I noticed that my key-frame-animations are not exported (as AnimationPaths) from 3ds max if the scene contains any osg-helper-nodes... Is this a limitation? thanks much rob

Hi Rob, I have not tried exporting a character with a OSG helper in the scene, but I am pretty sure this is a limitation. The WorldViz CAL3D exporter does not appear to have a concept of OSG nodes--just outputs CAL3D data. Hopefully the new version of OSG has decent character animation support that can replace our CAL3D dependency. It would be great to just maintain one exporter that can handle everything. However, the new OSG will not be available in Delta3D until the next version of OSG is released, 2.10 or 3.0 (whatever version number they decide on). What helper nodes do you need and for what purpose? I know that objects can be attached to characters at runtime. If you simply need a point, you can hunt down the specific bone by name that marks the spot. The Human Actor in SimCore should have this code, if you need to see it. Hope this helps out a bit. Talk to you soon Rob! Chris

Hi Chris, thanks for the reply! But I was talking about "non-character" animations, like (in my case) a bouncing billboard. So if I do a simple move-up&down-animaiton on a textured-plane w/o the billboard-helper the animations exports fine. But when I insert the billboard, assign the plane to it and do the movmeent either on the helper or the plane the animation isn't exported anymore...

I'm glad to hear that! osgAnimation and the fbx-support sound promising! thanks rob

I see what you mean. This is a bug for sure. However, I am not certain if it ever worked or if it broke after our modifications to the exporter. The billboard node assignment seems to be a bug too. It may take some time but I will try and hunt the bugs down and fix them. It's just a matter of getting the project time and deciphering the code again Please let me know if you find anything else regarding this. Thanks Rob! Chris

sorry for the confusion, but the billboard works fine except the animation-export (that is the problem for all osg-helper-nodes like groups etc) thanks for looking into the code rob
