google 'light portal', tweak dark multiplier (color mapping), increase camera's ISO

If that is group or component try exploding it first and see if a scale of that texture is changed. Also, are the faces of your floor object inverted?

Thanks Doppel, I uninstalled VRay and it immediately began running at a normal speed again. The issue was occurring for all file sizes, even upon starting a new file without any materials or parameters at all. Thanks again! Andrew

I just stumbled over my last question, here is a possible answer: thea render does the job for me, can be called via undocumented TH4SU.render("output.jpg") { callback.call } Has some flaws but generally works well.

Which version of VRay and SketchUp? If you are on the latest version, head over to the Chaos Forums. They are a little more active then these VRay forums these days and someone from Chaos might be able to help.

@teknoel said: You probably have some broken links to your image file. Luckily V-ray has a tool for archiving and repathing your images. under extensions look for v-ray>file path editor. this will help you fix the offending textures. Just had it happen to me last week and this is the correct solution. There was a map that could not be located on the network.

Hi, I had the same problem - on some surfaces in one SketchUp model the scaling of texture (in Materials Tray - Edit - setting different size of texture) was working, on some not (it was the same type of surfaces - wall). In SketchUp the size of texture was changing, but in the Vray render not. I don't know why but it helped to reverse the problematic faces and add the material with the texture again. Then it worked. If someone have the same problem, I hope this will also help him.

add context: trees, a road,cars and a background image 2: Use a domelight with an HDRI texture might help having some more realistic reflections on your walls and glass 3: use 2 point prospective as stated above

Same here with Vray 3.6

According to some rumors on the web, Nvidia will release a new 1180 card this summer. If you can wait a bit - I would expect a small price drop for the 10-series at that point as well.

hello, I knew of a software which made a transfer between v-ray sketchup and v-ray max properties, just that I miss its name at this point. It was a script for 3ds max which imported material properties such as glossiness factors and bumpiness slots... Though it can't be FULLY compatible since 3ds max is a different modeling platform than sketchup and will never be completely compatible with, also v-ray for sketchup is totally different than 3ds max one. And if you know your parameters you can apply them in v-ray for max too . I know you don't like working twice on something, but that's the best way sometimes.

Overlapping/fliped faces?

Check this fresh plugin: Physically-Based Rendering

Do you have the latest GPU driver installed?

I think it's because GPU rendering is fairly new technology comparing to CPU rendering, so i believe it's just a matter of time that will support every feature like in CPU.

@matucaa said: hi, i'm starting to use sketchup vray 3.0 and i'm trying to use the cut tool to render it, but when i get it finish the image is not quite good. it has ghostly plains in the main section. in the pregress windows apears this txt : Scene bounding box is too large, possible raycast errors. some one knows how to fix it?. attached images in this post! [image: kqv05.png] [image: kqMba.png] good find. I'm getting the same glitch when trying to render 3D plans/ dimetric perspectives using section tool. Hope there's a fix for it.

@cleeman10 said: Hi guys. I just downloaded a bunch of vismat files. When I open them in V-ray, the material looks different from the preview jpg included with the vismat file. When I open the vismat and see the preview IN v-ray (not the preview jpg) it looks different and much worse from what it should look like. It is a different color from the diffuse bitmap texture entirely, the reflection is out of whack... I don't know what's going on. It's like this for every vismat I just downloaded from vismats.com I've attached some pictures to explain my situation. Thanks in advance!!! It's a colour space issue. Go to the diffuse slot of the material and click on bitmap. Change the colour space from screenspace to linear space or vice versa. I personally, would prefer to go with custom gamma and specify what I'd like the material to look like instead. Usually a value of 0.5 works for me.

This topic is veeery old, bud I find myself having the same problem in v-ray 3.4 And I have a beast of a machine - threadripper 1950x + 32 gb RAM + GTX 1080Ti. No luck with xeon at work. Any new info on the solution?

the link to the image file has been broken. V-ray can no longer find the source file. the new version has a file path editor that will help you fix this. go to extensions/vray and look for file path editor.

hey, I get a message :vray encountered an error while trying to render, please check the ruby console for errors. can someone help? ruby console: "C:/ProgramData/ASGVIS/VfS/Ruby/3rdPartyHelpers.rb:63:in call'", "C:/ProgramData/ASGVIS/VfS/Ruby/3rdPartyHelpers.rb:63:in block in evalExternalCb'", "C:/ProgramData/ASGVIS/VfS/Ruby/3rdPartyHelpers.rb:59:in each'", "C:/ProgramData/ASGVIS/VfS/Ruby/3rdPartyHelpers.rb:59:in evalExternalCb'", "C:/ProgramData/ASGVIS/VfS/Ruby/VfSExport.rb:1981:in start_render'", "C:/ProgramData/ASGVIS/VfS/Ruby/R2PCallbacks.rb:538:in start_render_cb'", "C:/ProgramData/ASGVIS/VfS/Ruby/VfSExport.rb:1938:in direct_send'", "C:/ProgramData/ASGVIS/VfS/Ruby/VfSExport.rb:1938:in render'", "C:/ProgramData/ASGVIS/VfS/Ruby/R2P.rb:1482:in launch_vray_render'", "C:/ProgramData/ASGVIS/VfS/Ruby/R2PToolbar.rb:30:in block in module:VRayForSketchUp'", "SketchUp:1:in `call'"] Scene fully processed in 0.050 seconds
