What you think about adding an SSAO Compositor to Iris2? Of couse you could turn it off.
SSAO adds more realistic Shadow-Lithhnting to a scene. The famous german Game Crysis uses the the technique ;-).

pros:
Compared to other ambient occlusion solutions, SSAO has following advantages:

* Independent from scene complexity.
* No data pre-processing needed, no loading time and no memory allocations in system memory.
* Works with dynamic scenes.
* Works in the same consistent way for every pixel on the screen.
* No CPU usage – it is executed completely on the GPU.
* May be easily integrated into any modern graphics pipeline.

cons:
* Rather local and in many cases view-dependent, as it is dependent on adjacent texel depths which may be generated by any geometry whatsoever.
* Hard to correctly smooth/blur out the noise without interfering with depth discontinuities, such as object edges (the occlusion should not "bleed" onto objects).

Some more examples from Nvidia:

Hi Sience, It Has Been Long Time :)

I Think SSAO Compositor Will Be Good For Iris2 Client. You Should Add It :)

Regards

hm yes, but i can't find the time to add selfshadowing.

otherwise you will have no real shadows, this looks bad and is no real option. but i try to find some time this weekend :-)
