Problems with Lightwave angles in OpenGL.

hello to all!

I have the following problem with lightwave: the rotations!!
I’m programming a 3D engine to handle Lightwave’s scenes in realtime (using OpenGL as 3D reference API)… but if I directly use the angles given by Lightwave (HEADING,PITCH and BANK), the objects do not rotate in the same way as they do in LW… to be honest, they rotate in the right way
in some cases and in the wrong way in other cases.
Is there someone who can help me? (maybe telling me what kind of matrix rotation is used by Lightwave?).

Thanks To All

We had same problem.
Lightwave uses Euler angles a special way.
I don’t remember, but you have to make tests by changing the order in which the transformations are made (rotate/translate).
