Hi, I've a ztl model which I've lowered to the first sub d level. I've exported it at this level as an obj. I have tried to re-pose the fingers of the obj model in maya and export it back out. In Z brush I've imported the obj from maya and when I go up the levels in the ztl model there are crazy distortions. I haven't added any geometry to the obj. I've tried exporting the model without doing any modifications in maya and the same problem occurs. What am I doing wrong or what could be the problem?
