animation in gh? testing sunray reflection and refraction

Hi,

I'm trying to do some animation of my gh model but can't figure out how to. Tried exporting geometries out to rhino then key frame then delete and repeat but it got really confused because the geometries weren't tweaked in rhino, but deleted and replaced @ every frame.

Does anyone have an animation component/ definition or know how to solve this problem?

Another thing is I tried to test sunray reflection/refraction on a glass model, thing is the definitions I've got only work on surfaces. Any suggestion? I imported the model in from cinema4d, don't know if it was the problem, tried mesh it - didn't work either.

Please help and save my life!!!

Thank you, best x
