Motion checking tool that will take your animations to the next level. Now you can be sure that what you see in the user interface accurately describes the situation, observe changes in acceleration and speed of your curves and objects without guessing.
monitor amount of force of movement by acceleration
check you character\aircraft\motorcycle tilt by countergravity vector
create correct freefall acceleration by minimising countergravity vector
check speed by speed values
upcoming updates: armature support, relative speed, guide "physics for animatiors"
