Hi all, IMO, trying to create the shader->fixed mapping ourselves is a mistake. Others surely encountered the same promblem and it may have already been solved, or partially solved (as the ShaderGen Ralph and Brian told about). I think some people of the OSG community could even join an existing project to ensure that it fits our needs. Thoughts?
