MotionBlur Problem SP1 max 2008 64bits

[stilgarna]

Hello Vlado,

We've got a problem with motion blur :

With quick rotation I've got an annoying problem, First frame OK and second bad:


Here the render setup:


When I raise the geometry sample to 3 or 4 it's OK, but I've got a very big problem, a RAM problem, this scene goes to more than 12Gb... So I can't render it !

With geometry sample set to 2 I've got a 5.7Gb peak. all the renders works with 4Gb !!

It's a very huge scene (650Mb)

The problem only appears with rotations, translations are ok...

The only solution I found is to raise the geometry sample by object to 3 or 4 to avoid RAM consumption, my render to failed or to take a very long time to achieve....


So is-it a bug or is it normal???

I can send you a sample scene if you want to play with...



Best regards...

PS: I had no time to test it with SP2 and no time to reproduce with a simple scene... at the moment...

One more think about this scene...

When I use a simple vraylightMtl with full red or any color... there are no problem at all....

I' don't known if I m very clear about that... My English sucks...


When no shading no problem



Best regards....
