Slow rendering when using glossiness

[Jesper]

Does anybody have some ideas how to get a little more speed on my renderings when I use glossiness that's less than 1 ?

[jacksc02]

is this for still images or animation?

for reflection glossys, try lowering the subdivs to 10 or so when not using interpolation. If you use interpolation it needs to be higher.

Hey Chris

It's for stills.

For still use the interpolation option... that is what it is there for.

Ok, I'll try - have never used it before. What exactly does it do?

[Dynedain]

The interpolation option makes the glossies be generated through a mathematical algorythm that lets you get away with fewer subdivisions. Unfortuneately because of the math involved, it can't be used for animations because it will end up with slightly different results for every frame, resulting in televsion-static like effects on the glossy areas of materials.

Interp is similar to an Imap and no Interp is like Direct comp with GI.

I really dont like the Interpolation method due to it's Blurryness ... the new very deals with Direct a lot more efficiantly .. and faster i would suffer the longer render time's to get better renders.

[Dynedain]

actually, i've noticed with the new vray that interpolated can cause longer rendertimes than direct

[natty]

yeah direct is very fast now .... a pleasure to use

Is direct mode when the checkbox "Use interpolation" is unchecked or to you make the setting some other place?

[natty]

Unchecked ......... = use Direct
