Quicksilver reflections

[janiashvili]

Greetings!

Quicksilver renderer has almost no reflections(custom "include" reflection acts the way if reflections had only one iteraction). Is there a workaround for this problem?

Not an easy workaround. Basically Quicksilver functions like a game engine in the sense that there's no raytracing. Any reflections are "faked", similar to creating image reflection maps.

I was playing around with Quicksilver at some point and you could create the illusion of more complex reflections by creating the maps in another renderer like mental ray and then applying them in Quicksilver. Not a perfect workaround by any stretch of the imagination but the results can be nice as long as you work within the limitations.

I'm curious to know, has anyone else in the community has played around with the reflections in Quicksilver?

Reflection seems to be only having 1 "iterations" (have no occlusion or anything in reflection), which is less than creating image reflection maps.

and how can those be created and applied?..

Besides, game engines, notably Unreal, has raytracing(UDK has as I know, with dx11 only).

I created a series of videos explaining the basics of how you would create reflection maps for Quciksilver:

Like I said, there are a few caveats, namely:

    -Self reflections: Doesn't work well with this technique

    -Doesn't work for something like walls/floors

    -Animated objects: Since it's just one render it obviously won't update any translations done by any reflected objects.

Of course you could always create an reflection image sequence but the time spent rendering it may cancel out any time you saved using Quicksilver.

Hope this helps.
