Originally posted by blomkaal Having my first go at character animation, and I'm using half a sphere as an influence object to make the biceps bulge when the arm bends, and when I'm scaling the half sphere, it works fine, but when I'm using SDK the sphere doesn't influence the arm at all, it just goes straight through... Anybody know what the problem could be? I've tested the SDK and the sphere deforms like it's supposed to... careful of what is being driven. double check to make sure you have the correct transform or shapeNode being driven by joint rotation.
