Ambient Occlusion changes for v1.2

Post by AdamB » Fri Jul 11, 2008 7:15 pm

During the development of v1.2 I discovered there was a multiply of the Ambient Occlusion when blending by 0.5

Its just wrong.

Scaling of the brightness/color of the ambient occlusion should be controlled by the user through adjusting the Background/Sky colors and for v1.2 this is what happens. What this means is that you will find the Ambient Occlusion contribution when blending in v1.2 to be double what it was in v1.1 (because of the incorrect scaling thats now removed).

You need to adjust your Background/Sky color - typically adjusting down the brightness - to account for this.

I did consider trying to find a way of hiding this change but ultimately I decided its just wrong to be secretly scaling stuff and better to just nip it in the bud for the first Retail version.
