Hi Everyone, I am an absolute beginner, trying to develop a 3d viewer, importing models with animations from 3d studio in .x format. Following problem: I am able to load my x files with D3DXLoadMeshFromX but not with D3DXLoadMeshHierarchyFromX. With the models provided in directX samples everything works fine in both ways. I need to load the hierarchy 'cause I need to display animation. No idea about possible reason! Can someone help? Thanks in advance, JI
