new interesting observation. The other day 2990wx config rendered evermotion scene in 35 mins. Today with no change in BIOS (CPU clock and RAM clocks are the same) it took 27 mins for the same scene with same settings. Only thing that was different I have restarted comp just before rendering. This is 20% faster.

Problem was in memory disposition. I had 128 Gb of memory in first config. After I got 3970 x I took out 64GB and put it into new config. Remaining RAM modules were put in first four slots. So only two channels were used. Memory clocks were set to default / auto. In previous configs setting to auto meant that would work at declared clocks, but in both AMD configs that meant clocks were set to 2133 MHz even tough memory was 3000 GHz. After I put modules one to each four channels and clock was set to 3000 GHz my vray benchmark result was 27000 and mentioned scene render time was 35 mins. Which is huge difference compared to first result but difference is still 1,6 x (vray benchmark) and 1,8-1,9x (evermotion scene) slower compared to 3970x.

Hi! I have recently bought AMD Threadripper 3970x and tried to compare rendering times with my 2990wx config. So configurations are: 1. CPU: AMD threadripper 2990wx COOLING: Coolermaster masterliquid ML360 TR4 edition MOB: Gigabyte x399 Aorus pro RAM: 64Gb Corsair Vengeance LPX DDR4 GPU: ZOTAC AMP! Extreme 1070 8 Gb DISK: WD SN750 m.2 500 Gb PSU: EVGA supernova 750 G3 750 W 2. CPU: AMD threadripper 3970x COOLING: Coolermaster masterliquid ML360 MBO: Asus ROG STRIX TRX40-E gaming RAM: 64Gb Corsair Vengeance LPX DDR4 GPU: ZOTAC AMP! Extreme 1070 8 Gb DISK: ADATA SX8200 Pro 512 Gb PSU: Thermatake Toughpower Grand RGB 850W Gold Test scene was archexteriors 34 scene 10. Render was started out-of-the-box. No tweaking. 2990WX rendered it in 61 mins, while 3970x finished it in 19 mins. As far as I know 3970x is not 3x faster than 2990wx. I think that something is not OK with my 2990wx. Does anyone has experience with 2990wx? What could be wrong with 2990wx config?

Hi! I am doing this project and I get this result. There are no details on the ceiling. How to get them? I use vray 3.40. in max 2016. settings are: bucket image sampler 1 to 30 noise treshhold 0,005 global dmc / min samples 16 adaptive 0,85 irridiance map at high light cache at 1200 lights are mesh lights created out of geometry imported from ArchiCAD.

I have found solution to the problem here: http://forums.cgsociety.org/archive/index.php/t-806154.html I had distributed rendering turned on and default lights didn't work.

Hi! I am using vray 2.4 on max design 2014. I am trying to go through Akin Bilgic optimization procedure, but i hit the wall on the first step. I turn off lights and turn on default lights. All I get is black picture after is rendered. What should I do? http://www.cggallery.com/tutorials/vray_optimization/

I have found answer here: http://www.emailsignature.eu/phpBB2/how-to-get-a-unc-path-name-t341.html and one thing to note is that path should look like: \\server name\disk drive\directory name\... at first my mistake was that I put : after e. it looked like this: \\svejedno\e:\projekti\... this hasn'e worked. sythax that worked: \\svejedno\e\projekti\... Now I will test it on other comp.

what is unc path? is there any easy way to explain that? thank you for answer.

Hello! I have two computer i5 2500k and i7 3930k. I set a scene on i5 and all the data (project and textures) are saved on i5's HDD and is linked to my project through network drive. My drive E: on both computers is mapped as network drive, so it has letter Z and all textures have network path (Z:\projekti/...) When I render only on i5 everything is OK. When I render on i5 as master and on i7 as slave everything works. If I open that file on i7 through network drive (nothing is saved on i7's hdd) everything is rendered correctly. If I open project on i7 (still nothing is saved on i7's HDD) and add i5 as render slave I have problem. Everything rendered by i5 has no textures. Somehow i5 forgets to load data. v-ray I use is 2.2 in max design 2012. What should I do?

I've got answer on other forum. problem was I was using catmull-rom. I've changed AA filter to Vray Lanczos and it works fine now.

Hello! I am using max 2012 x64 and vray v2.20.03. My problem is on edges of connecting planes that has the same material. As you can see on the picture walls are white but edges goes black. What should I do? I use gamma setting at 2.2, and vray sun with vray lights on windows, adaptive dmc.irridiance map and light cache.

is there any automated way to see which materials are interpolated? and how to turn that off? I have few evermotion objects in my scene and I get that extra pass, which I would like to avoid. thank you.

What is the best way to transform imported OBJ mesh into rhino surfaces or solids? thank you!

found tutorial on that. is there any more automatic way to weld vertices that are on same coordinate?

thnak you for the info. on other forum I just got same answer, but since I am newbie can you give me a short explanation of that welding process?
