how to delete specific animation curve on import

Hello,

I would like to remove all curves controlling scale from my imported animation.

I do like to keep rotation etc. but I want to do the scaling myself on the fly (which currently gets overwritten). I've looked around for a while and the AssetPostProcessor looked like the way to go but I cannot access animations as they don't become components created for the imported Gameobject. So void OnPostprocessModel(GameObject g) does not work for me I guess.

What are the other options? By the way, I have not created animation in maya of course but the FBX exporter doesn't seem to care (and I don't see an option to change that behaviour)

Thanks in advance! Seb
