I ran into the problem of transfer of point cache data from Softimage Face Robot in 3ds max, 3ds max has in world coordinates Z-Up axis, while Softimage Y-Up axis. If you are writing point cache data in Softimage and then try to load it in 3dsmax’s PointCache modifier, then after the data is loaded (because mismatch axes) coordinates of the vertices are not correct and the model will seem inverted. This can be done manually using the snapping. To automate this process and avoid errors when working by hand, I wrote a small script that you can use in this situation.
