Volumetric Fog

(1/1)

cjwidd:
Corona Renderer needs a vastly improved workflow for working with, what in Unreal Engine might be called, Exponential Height Fog; volumetric fog effects for interior and exterior rendering.

Corona Renderer, even with the Fast Preview Denoiser, is too slow to render these effects, so much so that it interferes with artistic experimentation, look dev, etc.

A cheaper approximation could be appropriate, with an option to enable physical accuracy (e.g. caustics), but altogether there needs to be a better method for this that doesn't require vastly more expensive hardware to render on.

Kris H:
Hello cjwidd,

Could you please share with us some examples(scene and some reproduction steps) of the performance issue?
And also, what exact features of the exponential fog are you currently missing in Corona?

Thank you in advance,
Kris
