[osg-users] [build] using 3Ds Model in osgFX::BumpMapping and the Texture UV Coords for diffuse are not loaded

[Jannik Heller]

Hi Tobias,

The texture matrix is a fixed function state that may not have an effect when a shader is used. To get the desired effect, the shader code needs to get the texture matrix via gl_TextureMatrix built in variable and then multiply the texture coordinates with it. I presume the osgFX::BumpMapping shader is not doing this.

The osgFX::BumpMapping shader appears to be written in ARB assembly rather than GLSL, so it's a bit difficult to modify it. You might be better off writing your own shader in GLSL.
