Raytracing based on occlusion distance

[Morbid Angel]

Hi Vlado and dev team.
Do you think such thing is possible for the future to include. A raycasting of various sorts to be based of of the occlusion radius from object to object. This is to limit the various raytracing effects and improve render speed.

Yep, and I would even love to see an include/exclude for raytracing like the standard max raytrace material.

Does the cutoff help ?


Cutoff - this is a threshold below which reflections/refractions will not be traced. V-Ray tries to estimate the contribution of reflections/refractions to the image, and if it is below this threshold, these effects are not computed. Do not set this to 0.0 as it may cause excessively long render times in some cases.


Sometime I use it on large scene to seedup rendering...

There are plans for this, yes.

Best regards,
Vlado

cutoff is something like what i ment but, it does not have a falloff as far as i know, its just a hard cut off so if you clip too soon you will see a hard line. And it only works for refl/refr as you said. What Im referring to is more to do with any kind of ray casts, shadows, gi, etc.
