The reflection map in V-Ray is used to determine the "crispness" of the reflection. Not so much an image of what is reflected. The filter map would be used for the latter. Also you want a reflection/refraction background you need to set it to the "Background" map in our Environment tab - I'm not sure if thats why your not getting the results you expect?

this is what I am after, i have tried using the Filter map to do this but it doesnt quite work like it should. There is no sense of depth to the environment, just a map wrapped and reflected on the object.

This photo is 2 seperate renders composited into 1 render. Each had a different background map. I would like to control these reflection maps on a per object basis. It's the only way we are going to get great looking gemstones.

Right - ok I'm not explaining the "filter" properly. You are right - it is not going to give you any depth. The filter is not an environment map. It is a way to "filter" the color of the light reflected from the object. So instead of reflecting the light color it reflects the light color multiplied by the filter color. Or as you say "just a map wrapped and reflected on the object". At this time I suppose the compositing is the only true way to accomplish what your doing. The reflection/refraction environment is only accesible on a global scale. I'll look into per-object environments. I'm sure its possible- its just, unfortunately, not available at this moment from the plugins we ship with VfR.

I really hope that per-object environments are in our near future, beacause I feel that would broaden the capabilities of this engine. Don't get me wrong, I really am impressed, however I think that this would be a very powerful utility. Also, I believe it may be a little misleading to have it say "Environment" if it is not actually an environment map. It seems that all of the mapping option screens are the same, where some may need to be a little different from others. I know that VfR is still in the beginning stages, and, as I've said before, I think it is absolutely superior to any other render engine for Rhino.

brutal, thats what i had figured but just wanted to make good and sure. Unfrotunately, our user base is not going to want to composite anything. I fear that the only way to achieve what we need to achieve with minimal work from the user is to have premade materials for gemstones that just "work" in almost any environment. The only way we can ensure that this happens is by having environment reflections/refractions on a per object level. While the more advanced users will "get it" and understand the process, the novice users will not. Thanks Joe and please keep me posted on the progress of this limitation.

I agree with both of you - it will be the best interests of all of our users to have this functionality.

I've been playing with darker studio style environments.. the semi reflective materials are brutal on noise without adding lots more samples, but oh well.
I'd still like to get this smoothed out a bit more without getting massive render times. least squares fit seems to give me a better blurring result, but i think overall my IR map will need more samples.

... did you use LC and "use for glossy" reflections. Speed up blury metal very much.

[Travis Serio_cg]

V-Ray Jewelry

yes that does speed it up, but im trying to figure out how to increase the smooth blurry effect in a dark reflective plane without adding to many subdivisions or samples.
