Sphere Fade

[Tweekazoid]

I am not sure if it is even possible with this type of render to implement such thing,
but some alternative to vray's sphere fade (atmospherics) would cut down on render times.
(at least in theory it does)

in combination with render to texture it would drastically cut down on render times for animations.

imagine this:

big scene with mainly static objects and only few dynamic objects (transparent, moving etc).

render to texture would take care of diffuse, shadows...

sphere gizmo with spehere fade would take care of dynamic objects

and some simple aproach to get speculars and reflections

how does it work? Do you have some tutorials/samples where it is explained?

At about the middle of the page. It's an atmospheric gizmo which can be combined with several others and just the things inside these gizmos will be visible to the camera (with adjustable feathering).
Pretty useful thing for combining animated stuff with still backgrounds.

I guess this is obsolete with advanced masking, hybrid GI caching, shadow catchers, ...
