Re: [osg-users] osgExp 3ds max transforms
Hi guys, First of all, thank you very much for your replies! As Farshid said I was building my scene graph the wrong and I was applying the inverse transformation in a higher node, giving the impression it was ignored. Thank you!

Drawable::dirtyDisplayList() only forces a rebuild of drawables display list or vertex/element buffer objects, it won't affect transforms in any way.

[osg-users] osgExp 3ds max transforms
Hi, I am willing to export a 3D model from 3ds studio max to .osg files. Then, in my OSG application I assemble the exported model into a MatrixTransform node and apply some transformation. Althought, no matter which transformation I apply (rotate, translate or scale), it takes no effect in the final image. I realized that in the .osg file all the MatrixTransform nodes have their DataVariance attribute set to STATIC, but I already hard-coded it to DYNAMIC, but their transformations are still having no effect. Am I exporting the model the wrong way, or is the problem in the OSG application side? Thank you!

Re: [osg-users] osgExp 3ds max transforms
Hi, just a wild guess - could it be that the exported model itself contains a transformation node as a parent, possibly with an absolute reference frame? This can be checked by using osgconv and converting your model to ASCII .osg format.

Re: [osg-users] osgExp 3ds max transforms
Hi Jorge, Can you provide the code you are using to load the model and place it under the MatrixTransform? I don't know what could cause this issue other than the scene graph not being setup properly. Christian mentioned it could be caused by a parent with an absolute reference frame. The exporter does not change the reference frame of any transforms, so maybe you are changing the reference frame in your code? Either way, seeing some code would help a lot.
