Does it need to be Vray?

Using i7-4785t 32GB of RAM. It's ok until you start rendering something like this.

Hello -

I was wondering if I could "reprogram" a mini usb (flash drive) and use it as the Vray dongle?

I'm on a laptop and it would be super nice to utilize something smaller. Working from home, at the office or in a client's office it's terribly inconvenient to always be locating, plugging in the dongle and then starting up the license software. What if other software packages required a dongle? I love Vray, but this is extremely annoying.

Thanks in advance,
Joe

Sorry Joe, In the future we will move away from the Dongle but for 2.0 you're stuck with it. However, you can set it up as an on-line licensing system and host it from a home computer or work machine. Email us at support@chaosgroup.com and write in the header Attn: Ted Vitale and I can get you somebody who can walk you through the process if thats something you would like to pursue.

It could be a lot of things honestly. But most often its either a bad/overly complicated material, or a corrupted scene. Be sure you are using the latest version of V-Ray for Sketchup, found on http://www.chaosgroup.com under the downloads section after you log in. You can also submit your issue to support@chaosgroup.com.

You could try this method http://www.evermotion.org/tutorials/show/7875/anisotropic-shader-tutorial-using-vray-1-5-final-sp-1

For some reason I had one boarder for 3 groups that it didn't like, did 3 separate borders and it worked fine. Thanks for the reply!

I recently upgraded my laptop ram to 8 GB . How can I make V-ray use more RAM, so as to boost the performance? I am using Windows 8.1 (64 bit) and Sketchup 2015 (64bit)

It's already using the full available RAM as you're using the 64bit version. So if you want to use more RAM the only way would be to upgrade to even more RAM.

However, there is something that you should be aware of... if you want to boost performance you don't need more RAM but better CPU and GPU.

RAM is just there so you can open the model and work with it. If you have enough RAM for your model it will work. If you don't have RAM enough it will freeze.

It's the GPU and CPU that determine your performance Boost...

Having a laptop means you probably can't improve on those two and that's why I ditched my laptop in favour of a Big Tower Computer... It's a bit harder to take it to construction site, but I can do what I want with it at the office!

EDIT: There's another topic about this here: http://sketchucation.com/forums/viewtopic.php?f=15%26amp;t=63958

I might be wrong, but I believe you cannot use a linear surface for caustics. Caustics are a concentration of light due to a curved (lens) effect.

Would the same happen for a procedural texture?

tankyu @TedVitale_CG
it really work

You can set it to 0, and V-Ray will use as much ram as is available. Or you can cap it at something like 10,000mb if you want it to not eat all your ram.

As a side note, for slightly faster renders you can also turn off "Low Thread Priority" in your Global switches. This will throw everything your computers got (CPU) at the rendering, but you wont be able to do much else with the machine while its rendering like that.

See Attached.
Hopefully this helps.

Vray Options - Output

will try that. thanks!

also, when i tried to copy to the second model, NOT copy in place, the arrow icon turn to paint bucket icon. I DIDn't select paint bucket icon, and why the paint bucket icon show up??!! did anyone encounter this problem?

I invite you to visit my blog :

for better understanding to the real meaning for Sketch !!!!!!!!!!!!
you're Welcome

Well, since it seems that nobody is able to give me advise.. so i wasted several hours and watched 4 tutorials (until if found one that gave me some clues..) to find a solution.

The "trick" (just in case someone want to know) is to lower the color saturation of the parallel reflection until that effect dissapear. At least thats the only thing i could find to fix it. In the end, i dont get the reflections i would want in some areas (i really dont get vray lol, why is evrything so hard.. xD) but i prefer that instead seeing white dots without reason or "painted" areas with white for no reason.

Roo, Did you get any help yet?

Fernando did a short video on this a while back: https://www.youtube.com/watch?v=qyidgvF5WlY

This is a demo limitation. Please see the all the demo limitations in the downloads section at http://www.chaosgroup.com.

Is there any news on 3.0 yet thanks
