I can't zoom. Rotate and translate work fine but I can;t seem to zoom for some reason. I have tried everything I know. Nothing works. I can;t animate without zoom! Please help. How do I reassign a mouse button to zoom?
What kind of mouse are you using? Zoom should just be controlled by the mousewheel. Failing that, you should be able to zoom by holding Alt and left and middle mouse buttons and dragging left and right.
