SEX (interframe flickering) SEX

[oxygen_77]

You could try several things and see if they help... turn on shading noise reduction to reduce the splotchy look. Turn up your ambient light. Increase the number of rays per eval. If those don't help then I don't know...

like many things sex related - cheat

thanks oxygen_77
it always comes down to the render time game doesn't it. I've been working with radiosity for a long time, and i still don't think i fully understand every option in the global illumination panel. i'll try uping the RPE

As for you, Bytehawk
hehe -you're awful!
i like it ;)

I asked Dave Jerrard (http://www.advanstarbooks.com/lightwave/) what might cause flickering; here's his guesses:

1) "Interpolated" radiosity might be the culprit. For real radiosity, use "Backdrop Only" or "Monte Carlo." The "Interpolated" setting cheats on the radiosity by taking only a few samples here and there, instead of sampling the whole scene.

2) Instead of using radiosity, try replacing the bounce cards with Area Lights. If you want to use Area Lights with radiosity, use "Backdrop Only" radiosity, since "Backdrop Only" radiosity renders fast. You can use other types of radiosity with Area Lights, but it will greatly slow down your render.

thanks Celshader

it's awesome to get a well thought of answer to a problem.

monte carlo always takes a whole lot longer, and i have always hesitated to use backdrop. i'll give it a whirl.
i think those bounce cards are really screwing things up a bit, but the character just doesn't seem as rich without them.

thanks again for putting some effort into a response
i'll post how it goes

only for the sake of clarification have a look at eki's overcaster plugs for cheating this kinda setup. Even area lights will produce noize is you don't use a lot of AA (render hit - ouch) :p

--- plug ---
G2 will help too :bounce:
--- end plug ----

I questioned Dave Jerrard (http://www.advanstarbooks.com/lightwave/) about this; here's his suggestion:

Instead of high anti-aliasing, try checking the "Shading Noise Reduction" box in the "Global Illumination" section of the Light Properties panel to reduce the noise of area lights and/or radiosity used in a scene. It will add about ten seconds per frame, but that's still faster than a higher level of AA.

[Bytehawk]

indeed, Dave is right

[oxygen_77]

Dave may be right, but he didn't realize I already suggested it... hehe

[Bytehawk]

indeed, oxygen_77 was right all along
:beer: :beer:

*blush* My bad -- I'm the one reading this thread!

You indeed posted about shading noise reduction first. :)

[oxygen_77]

haha... no harm though... sometimes things need to be said more than once...

The better thing to do is skip radiosity all together.
Either go with One Ekis plugins or if you can afford it Shadow Designer.
They can produe really good fake radiosity effects.
