Hi
I'm currently wrestling with the coordinate system. I have three 3d objects (.3ds) that I want to use in my projects. When I render them on screen they are pointing in three different directions. I started 3dsmax, switched to the perspective view, I did a rotation transformation to make the three models point in the same direction but when I reload them in my application, they still doesn't show up correctly.

Note: I'm importing .3ds and exporting via .fbx

I know the basic stuff in 3ds but I'm no expert, I may have done something wrong. I noticed that 3ds max have several coordinates systems that you can apply the transformations. I tried some of them without reaching my goals.

Any tips?
thanks
