So, Vray is "SOOOO FASSSSSTTT" (and not too grainy btw).... if :

Spot on their Lele. I didnt mean map moiree and should have stated that more clearly. Sometimes moiree also pops up with detailed repetitive geometric structures and then filtering can help clean up the moiree mess

Ahah, indeed, yes.
That kind of moire (and i think i remember some, hem, detail in the renders @ macke...) is indeed helped by filtering

Damn ! Dude ! i didn't knew the impact of this feature : Treat Glossy Rays as Gi rays = Always.
it just gave me 5.6% speed increase compared to default value (only for GI rays).

Is there any condition/situation when "always" is not suitable ? (considering that LC is always used as secondary ?)

If yes i'll add it right now into solidrocks as another material optimisation option Many thanks for this tip !

Each day i love Vray more and more... !

hello

I have read this post and want to post my experiences with the "treat glossy rays as GI".
I have found some disadvantages with "Always" option.

image 1 shows the image with "treat glossy rays as GI" > "Always"


image 2 shows the image with "treat glossy rays as GI" > "only GI rays"


as you see the reflections from the environment are gone!

I think vlado should clarify the situation.

best regards

After reading vlado's last post in that thread I did not want to try this too much...

Thanks themaxxer for the tests, too!
