SSAO - Do I really have to notice it from across the level?

Graphics Shaders & Materials

Hi, I was wondering if it was possible if something could be changed in the script/shader.

SSAO works quite well for what it does, but there’s one thing that I would like changed. Is it possible to specify a Max Z distance to the shader so that at say a distance of 3 meters, SSAO doesn’t calculate objects farther than that? I ask because, while SSAO looks good up close, objects at a distance look odd (depending on down sample value and other things) especially if they’re moving. The odd effect gets more noticeable when fog or background particles are used.

Is it possible? And if so, could it be implemented in the future?

+1 - especially on Unity terrain, with SSOA on things in the distance turn pretty ugly at times.

SSAO uses depth texture internally, so you have easy access to depth values, therefore you could probably edit the shader so it doesn’t do anything if depth is over some value.
