[osg-users] best way for import 3d model with bump mapping

[Terry Welsh]

There's no simple answer to that one.  The way you render bump mapping
in Maya is probably a lot different than the ways you can render bump
mapping with OSG and OpenGL.  For a visual effect like bump mapping I
usually try to export models from Maya so that they have all the
textures necessary for the effect.  Then I use osg::Program to apply a
shader that achieves the effect using those textures.  There are also
other ways you can render bump mapping with less modern OpenGL
techniques, but most people prefer to use shaders.
