hi everyone,
i’m just putting the finishing touches to this scene for a walkthrough. can anyone see anything that could be improved upon.
thanks
Steve
uuuouu! Great!
Now I am working in a proyect animation. I have very problem with the seetting. could you say the time for frame? and your settings? very thks!
I’ll double that request for frame times, and settings!
Beautiful work!
de nada amigo
your english is better than my spanish!!
AA - adaptive QMC 1-4
irr for 1st bounce - med preset 40-20
lc for 2nd bounce - sub divs 1500 - sample size .02 - interp samples 10
QMC sampler - adaptive amount .85, min samples 16, noise threshold .002, gsm 3
the environment is set to 1.5, the direct light is on 4, vray panel lights at the windows on various multipliers.
the frame times are coming out at between 20-40 mins.
i didn’t store the lights with the irr map
hope this helps
steve
muchas gracias.
i hope your setting help me. mmm… but 20-40 minutes per frame i dont can. why not did you store the lights with the irr map? You referer to parameters of vray light? or Multiframe incremental en Irr map panel? light cache mode fly-trough?
My problem is that I have blind (spanish word: “persianas”) in windows and I had set property diffuse subdivs in lights to 2500 (fill light) and 3000 for a sun becuase the walls filll of artifacts… mmm if you want see it :roll: http://www.3dsymax.org/foro/viewtopic.php?t=10531&highlight=
PD: I speak english how a patatoes!! veeery bad! sorry. 
looking at your settings you have your global multiplier at 16, this is very high and won’t be helping your render times. to get more ambient light into your scene have you tried increasing the multiplier in the environment.
for your irr map, use a preset to begin with for testing either low or medium. and your HSph 30, int samples 20.
your LC looks OK at 500 for testing.
i must admit that I have never gone that high with the subdivs on my lights, probably the highest I’ve been is 32!
the maps were calculated first with LC in both the primary and secondary slots and set to single frame ‘flythrough’
the calculated LC map was then used when calculating the irr map in the primary and i used multiframe incremental and calculated every 15 frames.
here are my settings
hope this helps

Those images are fantastic! My only crit is that the car and grass that can be seen through the window don’t look good. IMO it would look perfect if it was just left as white. Otherwise spot on. 
shelsby, very thanks.
I am going to try it. i hope that your setting made me happy! 
shelsby, why set the parameter Scale to Screen in light cache? shouldn´t In fly-through animations be “World”? I think it before I read the official tutorial “Rendering a walk-through animation” :roll:
it officially tells you to use ‘world’ in that tutorial, but when using world the same sample size is taken for the whole scene. since my scene is fairly large with a ground plane and billboard for scenery i have decided that ‘screen’ would be better as I’m not too bothered about the sample sizes far away from the camera. it would be a waste of memory to get very accurate samples for geometry so far away.
Pretty good overall. Ditch those awful Evermotion bed pillows which look like raviolis.
ziddemizard:
The diffuse subdivs you are talking about in the light properties are only for if you use photons for 1st or 2nd bounce. Changing these will not help you AT ALL.
You need to up the shadow subdivisions in the light rollout.
shelsby:
Awesome render mate!!
Not sure if you know but putting vraylights at the windows blocks all environment light, and the direct light as well. Although you can get the direct light to work properly by tick invisible on the vraylights.
You can get the environment back in by ticking skylightportal on the vraylights.
Pretty good overall. Ditch those awful Evermotion bed pillows which look like raviolis. :lol: That’s what I thought right away, after, of course how much I was blown away with the quality of the renders. My only addition would to be to add a more interesting lighting scheme to your last image.
Thanks alot for sharing your settings. It’s good to see decent render times with this quality.
DaForce, thank you. I’m stupid! I have never used photonmap. I had increased the shadow subdivisions value right before I read your post. That was a ‘white-belt’-degree mistake :roll:
shelsby, copy. thanks you.
shelsby, sorry by offtopic. If you want I delete link. But i need a little help.
my new setting:

What can I do for acelerate render?
allow me to offer some more advice.
For your IR, use 50 hpsh and 20 interp, for LC lower to 1500subdivs (if only for single frame) , untick stored direct light, change scale to screen, turn on pre-filter set to 20, change filter to nearest.
Change noise threashold QMC sampler to 0.004
Also make sure that in the GI rollout that both 1st and 2nd bounce are set to 1.0
DaForce, it is an animation and 50 hpsh and QMC sampler set to 0.004 means more render time, doesn´t it? and, as i’m on a dead line, i ain’t got time enough.
“1st and 2nd bounce to 1.0”.. I need that room to be dark because I’m gonna show a video on the screen
i need fast render time…
ahh right so your after speed primarily.
hmmm well as long as your calcing and saving your IR and LC before hand then you only need to load the IR map when rendering as it stores the LC information in it.
Make sure to keep your glossy material subdivisions down to help speed things up.
And if you change to adpative subdivision AA it might be abit quicker and smooth.. althought not as accurate.

thanks da force
I knew about the vray panel light and the direct light scenario but the enviroment thing is a new one on me!! i’ll look into that.
you say later that i only need to load the irr map from file for the final render. i normally calc the lc on flythrough, then use this when calculating the irr map. then on final render load both - what difference will it make using your method?
thanks
Steve
really nice images - I would change that orange picture in the second image for a mirror - there are too many colours competing in there, it makes it seem very busy.
You can save the lc and irr map at the same time - I calculate the lc using flythrough and save to file and irr map with incremental add and auto save (dont render final image checked). Then use these two saved maps for the anim - saves on sending renders to the farm - the lc gets calculated first then the irr map after - works a treat.
