Vray too slow while rendering
-
Hi everybody , I have a problem with starting rendering ...
When I click the Render button it takes several seconds to start rendering and system tray shows me "not responding" for sketchup , but it starts rendering after (let's say) 15 secs . There is also a message says : " V-ray is currently processing your scene , please wait..." . But it is not normal , no matter what scene I want to render I have this delay , even on an empty screen !! I think it might be a V-ray software problem cause when I installed v-ray it causes a big delay to SK launching . and the problem solved after uninstalling v-ray .
Any idea ?

No one should be waiting 5 days for a rendering unless they are rendering on a 486 (some of you youngins might not even know what this is).
My first go to is, displacement - unless you absolutely need it, I would not use any. If you are downloading vismats from the web you might have displacement on a material and not even know it. Also, you might have high subdivs on a material and not know it.
There a hundred factors in VRay that can increase render times, so I don't think any of us could tell you exactly what it is, but I can tell you that if you are using the default render settings and test a render at 800 wide and its taking a long time, you have displacement somewhere most likely. One way to try to turn it off is try through the global displacement setting and set the amount to 0. If the render starts quickly, now you know. If not, then try setting the global subdivs multiplier to .25 and see how this works. If still very slow, then you might have a texture map in there that was downloaded from the web that can cause issues. I tend to stay away from stuff downloaded from 3D Warehouse as much of it is crap and has texture maps with funky file names and characters.

if you can zip up the model, as well as any external files that are referenced (textures, cached map solutions, etc), and upload it to a place like google drive, soshare, or mediafire, someone might be able to track down the issue faster than just looking at screen shots.

That is normal. V-Ray has to grab all of the information in the sketchup file, and convert it into something that can be rendered. All rendering engines require some time to process the scene prior to rendering. In our 1.6 beta, we have added some additional features and optimizations that cut down on the delay significantly.

Yes, our plugin loads when you launch SketchUp, and it takes a bit of time to load dependencies and get our plugin up and running. You can disable our plugin in the Window->Preferences window. Click on Extensions and then uncheck V-Ray for SketchUp. Note, unloading our plugin requires you to restart SketchUp. -
Thank you Devin ,
I understand that , but I think this is a different issue , cause I see "Not responding" message . In a normal start you do not see "not responding" message . Or I am wrong ?
I even have the delay when I try to render an Empty scene !!By the way , I use Win7 / 32bit / 4GB ram / Intel core2(tm) quad 2.83 GHZ CPU / Sketchup 8 / V-ray Version 1.49.01
Kind regards .

I'm going to be a little crass on this one. It is Monday afterall.

Get 1.6 (LEGAL COPY)

Get a computer with an i7 processor (i5 at a minimum). Desktops are insanely cheap now. You really need a decent multithreaded processor and RAM if you plan on rendering with ANY render engine.

Stay away from 3D CrapHouse models. Whenever I have had an issue when a render just stops working and is stuck, it's because I have some random texture or something wonky that came along with a 3D Warehouse file. One time I had a model with Asian characters in the texture name and this made VR grind to halt.
Do this as a test. Go to the Options panel - reset to defaults - then go to Globals and try a test render with Override Material on. If that renders quickly, then you know its a material killing your render times. I would try a purge all, then run down you list of materials. Look for weird characters in the names and in the texture tiles. Then I would crawl through the VRay material settings and look for any materials that might have high subdivs or metals that use Ward or Anisotropy. I find that this has also made my render times hit rock bottom.

The "not responding" message means that SketchUp is busy, and unable to respond to any input what so ever. That's because we are using every possible bit of processing power and memory that is allocated to SketchUp, in order to process the scene and render as quickly as possible.
