Thanks Andybot! you helped me a lot.

oy! Thanks, andybot. Much appreciated

I just now read on the Chaos Group forum that with DR, each bucket calculates all the irmap passes individually, so you don't see the multiple pass with DR enabled. It is expected behavior apparently. http://forums.chaosgroup.com/showthread.php?80428-Only-one-irradiance-map-pass-! (registration required)

@sketchuh said: Thanks Ted for the comment. and I did contact sales and support from chaosgroup! But the sad reality is They did tell me I have to pay for a new license fee, because its due to abuse of dongle license use. I think it really applies to Asian market. I told them it's not fair and it doesn't make sense. It really hurts customers at the end. a policy can be bad. you have to be brave enough to tell them it's wrong. I still don't like that policy at all, even though I really enjoying using vray for su. I'm glad I found my dongle at the end. There are some specific requirements that have to be met for us to replace the Dongle. I think your case was a special one which is why we were not going to replace it. I'm going to send you a PM with some more specific instructions.

hi andy, thanks for the reply. I tried another render with everything you suggested (except linear color mapping & resetting the gamma), and I even moved the TV stand 1mm further from the wall (which mathematically should resolve the same normals problem), but it looks almost the same and it took two minutes longer to render Also, I need to add, that in my previous post I ended with 32 subdivisions on the dome light; I'll probably edit that in.

@andybot said: @jpmorla said: ^^ Actually, I think I do not need to try render with materials overwritten. See, different groups/components render (or do not render) depending on the scene. So I do not think the problem is a material issue. I think this is a VRAY bug. You would do best to upgrade to the latest version and service pack. There have been numerous bug fixes since this issue first came to light. This are my specs: OS: Windows 7 SU PRO 2014 VRAY 2.00.24942 If I am correct, I am using the latest service pack.

@andybot said: when you have a very bright background, the color will be picked up by the anitaliasing at the transparent edges of your render. A few things you can do. quickest is in photoshop - go to layer --> matting --> defringe, and use default 1 pixels make your background environment darker to match your underlying image. hide your background materials in your render (in the material properties, check the option for showing only in secondary.) You can then use your background image in your vray viewport by setting it as the environment background, and use "screen" mapping. Thank you - I have used enviroment photo and defringe in PS and both together works

Thank you! How simple!

Make sure you have the latest V-Ray installed, this was an old bug that was fixed when VR could not find a texture.

Still having problems after converting each model to a proxy mesh. I'm not sure if it matters but I didn't change the triangle count when exporting. Even trying to render a rather simple scene within the same model I get an error at the bottom on the window. It says to check the ruby console for errors but when I open it the console is empty.

I'm not sure which version I'm running... it was bought for me about three months ago through work. I don't see any info in SketchUp/VRAY that says which version it is, and I'm not finding any info in the application folder. I'll contact VRAY directly.

@eidam655 said: @valerostudio said: Why not just use V-Ray in SketchUp and save that hassle? 32bit memory limit. Try the 64bit render workflow: http://docs.chaosgroup.com/display/VRAY2SKETCHUP/64+Bit+Workflow

um, I hate to ask, but what version of vray are you using and did you get it through official channels? If it's a legit copy, sounds like you might need to reinstall. If you're still having trouble, you could send an email to Chaos Group support for further assistance.

Are you using DR spawners?

check your Fresnel reflection value of your floor material, looks like it's too low (like 1.4 or something.) increase it to 2.0 or increase your glossiness value.

Will try the version from chaos. The retailer told me this was the latest there was, guess they haven't gotten the news yet. I'll let them know.

@andybot said: The other thing is to use a dusk HDRI in a dome light to get the nice bluish lighting like you see in the picture. Andy Yes, this is a must. Get access to free ones here... http://www.hdri-hub.com/free-samples

Same problem here too. The worst part is when you do not have a wibu key with vray inserted into usb. Vrlservice is constantly opening and closing, looking for license I guess, therefore icon of vrlservice in the dock is appearing and disappearing. This is blocking fullscreen mode of many apps like VLC, Power Point, AutoCad etc. Each time vrlservice is looking for license, app closes the fullscreen mode and returns to desktop etc. Right now, everytime I go out with rMBP I have to have a wibu key with me because viewing presentations and movies in fullscreen is impossible. Like kalu I also have to force quit the application when I want to shut down the notebook. Thank you for the fix in the next release

This is the interview with Alex Roman if anyone is interested. https://www.youtube.com/watch?v=DYW_SgiWEoo Also, take note that this video came out years ago, when computers were slower, V-Ray was older, and this quality was inconceivable up to the point he released this work. His techniques are now considered cliche in the viz industry just because so many people have copied them over and over.
