I have a scene with a perspective camera and far away from that, there is an other (orthographic) camera. When I set the second camera’s render target to a render texture, suddenly the volumetric fog gets noisy. I tried making a box volume and apply the fog only to the area where the perspective cam is, but that didn’t help either.
You cant use more than 1 camera with HDRP, it will cause problems and kill your performance badly. Take out one of those cameras, and watch your performance increase.
Is this true? So in effect, there’s no point in my trying to create a second “viewfinder” camera in an HDRP project and “record” a “Movie”
(I’m speaking from a Virtual Production/ cinematography point of view)
Yes, its true, check hdrp documentation as well as other devs experiences. But i know a work around that has worked for me (performance-wise): Set up a server/copy/test version, and “strip out” the second camera as much as possible.
Now, your thinking from a cinematography aspect, so strip and drop all settings, then slowly bring up certain needed post processing/hdrp base settings, shadows, etc. to taste, as its what you can do without, more than its what you can do with.
Im getting visible banding and terrible noise as well on all kinds of scenes. This is from Spaceship demo.
Is there a way to increase the volumetrics quality?
Cant seem to find how to achieve a proper artifact free volumetrics / fog.
Thanks for any info.
Found a setting that is hidden in Fog override, but can be shown using the “More Options” button with gear icon called “Filter”. It gives some improvements, but still not the best.
Thanks @Dirrogate for the tip. I’ve been rushing and missed the slices setting.
Now the quality is good, although banding can appear on plain surfaces.
For me, the performance impact of the secondary camera is just 2-3 fps. Although I’m only using the 2nd camera to render some text to a renderTexture so maybe that’s why.
