Hey all, im new here and quite new to blender.
I want to animate a spider like object but only certain faces, everytime i try using keyframes, and IPO curves it wont let me, it just wants to scale the whole object, and not just certain points, ive added some pics of how i want it to be scaled, hope that helps! Thanks in advance!
