View Full Version : HDR Prefilter

03 March 2006, 09:43 PM
Hey all,

Can't find anything about it in the docs / what's new sections, so would someone be kind enough to explain what it actually does to the HDR image ?

Hey MoodyB,

I haven't got a complete answer, but below was some info I got from PmG with what I thought at the time was an HDR bug.

"... you forgot to turn on the HDR prefilter button to let the system know that you wanted to use the light probe image as diffuse light instead of a reflection map, so you got a straight reflection of the HDRI map..."

Hope its helpful.

Thanks rush, that makes sense. Kind of odd how the HDRI still emits light with the prefilter off though. Lets' see if they've tweaked anything in the new release when it appears.
