[osg-users] Multiple Render Targets - Request forComments/Testing

[Wojciech Lewandowski]

I tried to compile it and link on Windows with latest SVN. Compiled and 
linked fine.I ran osg prerender and shadow exmples with fbo. Again no 
problems. But frankly haven't tested MRT functionality at all.

Cheers,
Wojtek
