Thanks Gerrit, sorry, my stage setup was already the same as you suggested.
So it also doesn't work with: HDRStageWithSSAO -> ShadowStage -> Scene I'm looking forward to your patch! :D Thanks a lot, Stefan -----Original Message----- From: Gerrit Voß [mailto:[email protected]] Sent: Dienstag, 14.

For the case with only shadow and hdr stage the setup should actually be the other way round, e.g. HDRStage -> ShadowStage -> Scene as the HDR stage is a simple postprocessor. I would expect it to run last in all cases. I'm nearly done so that the shadow stage respects the target buffer format set by a parent stage. I hope to commit this later today (latest tomorrow). Once this is done I will add our SSAO implementation and see how this best fits into it. Let me run some basic tests with this setup first so I get all the implication of the g-buffer part. I'll get back to you as soon as I have a little bit more information. kind regards gerrit ------------------------------------------------------------------------------ AlienVault Unified Security Management (USM) platform delivers complete security visibility with the essential security capabilities.
