Hi, Here's problem 2) for me - aside from the Copying Keyframes problem (but very similar). I make some keyframes for different parts of a character (it's actually a run cycle). Later in the animation, I want to make everything that was on the right swap to the left side and everything from the right side swap to the left (to complete the cycle). The Swap Left & Right tool seems perfect to do this... BUT... 'sometimes' it doesn't swap all the parameters. It swaps some of them but others seem to be a mix of what was already there and the new keyframes. This has got me really stumped. There's something obviously interferring with the tool doing its job but I have no idea what it may be - it's just a simple run cycle. Is there some other setting that might be the culprit? Anyone have any ideas? Thanks in advance. ALEX KUZELICKI hybrid@bigpond.net.au
