Hi,
I've used HDRI's for environments but plugging the texture into the texture environment and this works well.
However instead of doing that I'd like to map the image onto a polygon and the place this behind my subject. However I've noticed that the image loses all it's 16bit info. I've tried changing gamma and brightness etc but it looks like 16bit isn't supported in surfaces, whereas it is in the render target, is this correct?
Thanks, Alex
