Interesting, I never thoguht about it this way. Basically I am doing the same. I have a maya file where I author multiple animations. However, I was assuming the import range would be relative to the exported animation and not taking into account absolute frame ranges form either maya or blender. And to be honest, I don’t think this is very intuitive and user friendly design. In Maya I often move certain animations around and the actual exported frame range might change here and there. However, the duration, thus the total length of the animation will remain the same. Setting the import frame range relative to the amount of exported frames would work much better in my opinion. Anyways, thanks for clarifying!
