Dome light disable atmospheric shadows toggle

[LudvikKoutny]

Hi,

I've noticed that in V-Ray 3.3, native Max's "Fog" environment effects casts atmospheric shadows when used with domelight. V-Ray sun. V-Ray sun has the toggle to turn them off, but V-Ray Dome light does not. Is there any way to prevent dome from casting atmospheric shadows when Fog environment effect is used?

Also, was this always this way? I've been using Fog a lot with V-Ray, and never remember encountering this issue. So I am wondering if there wasn't some change in regards to atmospheric shadows with domelight after introduction of aerial perspective feature.

Hi,

Yes, it has always been this way. I would suggest to use the native Max lights for scenes with 3DS Max Fog atmosphere effects in order to have better control of the final result.

Well, it's quite hard to get IBL from HDRI using Max's native lights

Non the less, thanks for answer.

( I tried mapping emission slot of VrayEnvironmentFog with blurred spherical environment map (same thing i do with Max's native Fog) but i am getting weird results with extreme rendertimes that way )

Yeah, that's true.

I have confirmation from our Dev team about this implementation and we have it now in our "to do" list. As soon as this option "cast atmospheric shadows" is added to the Dome light parameters we will let you know.
