A question about blend shapes and curves/straight lines. Maybe a little stupid..
When setting up character deformation I often refrain from using blendShapes, due to the fact that they interpolate in straight lines, which much in life obviously does not. I'll use clusters or other techniques to get curved paths of movement instead.
But I often see people recommend setting up e.g. eyelid deformation with shapes, using one or more in-betweens. The problem for me is that it, by default anyway, still creates straight lines - just more of them. And to me that does often not look very good in animation.
I know that you could achieve curved movement by driving several shapes via set-driven, but it seems to me there should be a way to get smooth interpolation paths between shapes just by setting up a target and an in-between shape. Maybe with a script or plug-in, that let's you adjust curves in the graph editor or some thing like that.
Anybody know how it's done or what script does the trick (if any)??
Thank’s a lot!
