some damn fast render time's

[natty]

hi guy's
just doing some test renders today and started playing with the QMC and started to produce some very fast test renders... have a go yourselve's.

here are the settings, see what you think




Please bear in mind that these settings are purelly for test renders

[cocolas]

can you post some images of what those settings produce and most important , render times??........
those settings look really odd/different from everything I've used/seen before.......but hey, if they get faster tests I'll be the first to adopt them

show us more...

thanks natty,

paul.

natty,

that stuff is GREAT!!!!!! I shouln't have doubt ya

with my usual test settings
----------------------------------------------
-4/-1 min/max for Imap
0.5 clr tresh
0.4 normal thresh
40 Hem subdv
20 interp.

(default settings for QMC)

Max tree deepth 63
face/level coef 0.5

AA > fix rate = 1

color mapping > HSV esponential darker = 1 brighter = 1
--------------------------------------
it was taking a little over 17 mins calc Imap and rendering from scratch.

with your settings the whole thing came down to about 11 mins.!!!!

the only problem I see is that even though it calculates the Imap VERY fast it seems that the rendering itself takes almost longer or as long as with my above settings.......so I need to work on that....but it's still a HUGE improvement plus the quality looks the same as w/ my old settings above, good for a test rendering...

we should investgate this further...

thanks for sharing!
I'll keep playing w/ it...

cut the QMC min sample in half to 50..... and the direct comp down to 2 and 2 .....interp to 150..... watch it rock

[cocolas]

.....and rocking it does, my man

In the rendering above I had 20 lights and your settings (first post) and it took 11mins...w/ AA set to fix rate = 1 ......and full refelctions for glass..
now I added 3 times as many lights (60) and added your new settings (above) and its still only increased of 3 minutes.....

damn nice, Natty!!!!

w/ my original settings (see above) it probably would taken around 35 mins.....with yours took only 14 mins.....

thanks much

paul.

hello natty,
i guess something is weird over here, because i used to played with this settings some times ago and in my tests i've need to decrease min samples and not increase it. For exemple, i take a try now and render a image with 100 at min samples, just like you. My time render was 2:34, than i put my old values, 10 to min samples and i got a render time of 2:10. Take a try in your images and tell me if this is right. The only difference betwen us is that my image is a external image with two buildings and yours is a interior image, perhaps this must the diference.

see you bud

[natty]

ok, working now

mhm... more samples = more calculation = slower.

whats wrong here?

[RErender]

mhm... more samples = more calculation = slower.

whats wrong here?

It is the QMC values, it is set to cut off most of the rays.
