[osg-users] Render to texture and Shadows

Hi All, I am using Light Space Perspective Shadow Maps for shadowing. I would like to render the shadowed scene to a texture, so I have another camera on top of the shadowed scene. It looks like following: root | RTTCamera | ShadowedScene I also render a small sized screen aligned quad which

I found out that one can simply call stateset-setMode( GL_FRAMEBUFFER_SRGB_EXT , osg::StateAttribute::ON); to enable sRGB mode. An explicit OSG support is not necessary. I didn't try something like this with sRGB texture formats yet. tugkan Tugkan Calapoglu wrote: Hi, I couldn't find sRGB

Hi Tugkan, Somebody recently, also mentioned that nested cams not work with LiSPSM. Frankly, I have no time to investigate this. I would recommend using RTT slave views instead of nested RTT cam. I think this will have more chance to work as intended. I apologize for trouble. Wojtek
