I have a 3ds file that a friend made in 3dsmax which I am using conv3ds to converte it to a .X file. When I open the .x file in the mesh viewer it looks like the model has been flattened. He didn''t do anything different when creating this model then any of the others I''ve converted and they''ve all turned up fine. Does anyone have any ideas what might be the cause or solution to this? Thanks.

You probably have to swap some of the components of each vertex. Since I don't have any experience w/ Direct3D's converter, I can't tell you whether this happens automatically.

Direct3D is a LHS and so is my engine. .3DS is not, however and to orient models correctly I must do the following before storing the vertex :

X' = X;
Y' = Z;
Z' = -Y; // Minus for LHS, Positive for RHS

Maybe this will point you in the right direction (stupid pun actually not intended...)
