I have a model of a swordsman created using 3D Studio. I have the .3ds file exported from 3DStudio. I am converting the .3ds file to .x using conv3ds.exe utility that comes along with DirectX. The problem is after converting the model to .x file, if I look at it using DRDIM .x file viewer (that comes as a sample application along with DirectX), only parts of the 3D model (One leg, Hip) appears. All the other parts dont seem to render at all. What could be the problem. Thanks Arun
