Add maximum roughness cutoff to SSR to improve performance
Browse files Browse the repository at this point in the history 
In a test scene with mixed rough and non-rough materials, this saves
0.15-0.3 ms of GPU time with very little visual artifacting
(GTX 1080, 2560×1440).

The roughness cutoff can be adjusted in the Environment properties.

The fade-out distance for screen-space reflections. Affects the area from the screen-space reflection to the "global" reflection.

<member name="ss_reflections_max_roughness" type="float" setter="set_ssr_max_roughness" getter="get_ssr_max_roughness" default="0.75">
The roughness cutoff value for screen-space reflections. Screen pixels with roughness greater than [member ss_reflections_max_roughness] will not compute screen-space reflections. Higher values result in more visible screen-space reflections and less artifacting, at the cost of GPU performance. The default value is tuned to keep nearly all visible reflections while improving performance compared to not using a roughness cutoff ([member ss_reflections_max_roughness] = [code]1.0[/code]).

The maximum number of steps for screen-space reflections. Higher values are slower.
