Brian, JP, The osgmultiplerendertargets example uses (by default) GL_FLOAT_RGBA32_NV, rather than either GL_RGBA32F_ARB, or even GL_RGBA16F_ARB. Could this be a card issue?
I would be interested to know whether this example works for you if you change to GL_RGBA32F_ARB or GL_RGBA16F_ARB. I admit, I haven't tried it myself yet - and now intend to - but certainly in my own app (on ATI), I have had issues with GL_RGBA16F_ARB and GL_FLOAT in the past. Things might be better now. David
