Hi, So I have been experimenting with shadows in OSG using the ShadowMap shadow technique. With the default OSG implementation and every custom shader in my scene graph disabled the shadows work correctly. Once I turn my shaders on they stop working. This is understandable as he OSG shadow shader will be overridden. I then reimplemented the shadow projection code in my pixel shaders, but then still no shadows. I am not too familiar with the OpenGL fixed-function shadow pipeline. If you do not provide a vertex shader does OpenGL generate the proper texture coordinates by default. I saw that OSG was creating a TexGen attribute and applying that after shadow map creation. If I am implementing custom vertex shaders should I be overriding the ShadowMap and not allowing that TexGen to be created and then generate the proper texture coordinates in my vertex shader? At this point I think all that is missing is the proper texture coordinates for shadows to be working for me. Any help woul d be appreciated. Thanks in advance!
