there are walk on anims for both of the stock sets... as for making one that fits both, well thats just not do-able for 2 reasons:
1: we dont have the stock models in 3dsmax to use as reference for the camera path
2: we never figured out how to get camera anims exporting properly, i was going to try and figure it out again for excalibur but since we are using immersion for interior stuff like this it shouldnt be necessary.
