I am currently trying to make a rollercoaster in OpenGL. To do this, I prepared the track in Blender (following a Bezier curve) and exported it along with the curve as .obj files in OpenGL.
My problem is that I can't find a way to export the normals (or TILT values) from Blender. What I have already done works fine but I also need to export some information concerning the orientation if I want the camera to point in the right direction in the final animation.
I know that a few questions concerning this issue have already been posted but I couldn't find an answer in any of these.
Could anyone help me with this? Thanks in advance!
