View Full Version : FBO and GL_RGBA32F_ARB

I have been successfully using FBO on my Geforce 6800 GT w/ the latest beta drivers

I was hoping to set a particular instance of an fbo with GL_RGBA32F_ARB to ensure that I could then use the result as a vertex texture

It seems, though, that when I attempt to set it to 32f I always get an unsupported error.

Would this just be due to a lack of driver support perhaps?

I can set it to just about anything else, including RGBA16, etc. Am I possibly missing something?

Would I have any other options here?

Or am I going to have to revert to reading back from the framebuffer (or using a pbuffer) and placing the desired contents into a 32 bit format?

Thank you,
-Ian

Don't forget to set your mag and min filters to NEAREST before you attach your texture to an FBO.
