Frosted glass in animation (vray)

[jorgeruy]

Good morning guys.

I'm doing an animation inside a frosted glass where the foreground. The render takes 5 minutes the frame, but when it comes to glass takes 25 minutes. The crystal is a simple material with vray glossines of refraction at 0.8 and subdivs 8. Can you tell me to help get a frosted glass that does not consume much time frame?

Thank you very much

Jorge

 

P. S. Sorry for my English, I help my friend google

A Vray light material composited with a gradient ramp set to box or an edge-gradient you make in photoshop usually works well when the frosted glass doesn't have to be a main feature. Just set the light material to multiply by opacity, compensate for exposure, and emit on back side.

For an animation I'd argue that glossy refraction is not worth the extra render time. Turn off your glossy refractions and your render times will speed up dramatically. Another option/idea is that you can uncheck "trace reflections" under material options.

I tried to remove "visible to GI" of frosted glass and won some time, there is no change in the image but in the render time. What's wrong for being disabled by the GI?

 

Erick, if not disable glossy refraction with the frosted effect, and is an important element in the animation display

 

Corey, I'll try what I comment, but I fear it may create flickering in the animation

 

Thanks for your support

You'll still get a frosted effect if you don't use glossy refractions. If you set your refract value to a medium gray you'll achieve the frosted effect in much less render time.
