FLICKER DILEMMA...
 
Hello for everybody!!!


The Lw, render the high resolution procedurals and bitmaps, in subpixel calculations,, but if your render the same frame twice, you see the pixels renders in difenrents locals, turn the animation flickering, also this occurs, in a caustics or radiosity with HDRI maps...

the question is...

Have a technique to solve this, whitch no loss of detail?

I like to se may render with high resolution , with no alias or flickering,,,




:D

hard to judge from a distance...

are you rendering with AA? which settings? what does "high resolution mean exactly? (numbers please)

check rendering with shading noise reduction and enhanced medium to high AA

Hi Philip!!
MY AA settings is ok, I dont use Adaptive sampling, and even in Extreme AA this problems occurs, if I put a very high resolution proceduralor bitmap , as example...
they never render the same twice If i advance one frame.
example..

I presse F9, I see a result, If advance one frame press again I see the image rendered , render of a sequence, the object is in another position.
I see the pixel of textures renderer not match between frames ,this problem create flickering in textures, I send a test for you,, to see, Is only a test, for detecting the problem
the bump flickering in a sequence fo images...

Tks for helping...

I've heard of similar problems posted some time ago on Yahoo groups.

If I remember correctly, one sugggestion was to turn of AA altogether and simply render at 2x or 3x resolution. Then downsample in Aura/Photoshop/Premiere/AfterEffects/Combustion (whatever paint/comping application you use).

If the final output is for video, you may also want to try rendering fields.
