@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.

oy! Thanks, andybot. Much appreciated

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.

@thomthom said: That limit the size of your render to the size of the viewport. If you need highres images, but in the same aspect ratio of the viewport use the "Get view aspect" button and then lock the aspect ratio. Then you can increase the output size and still be relative to SU. So if you save out a 3000px wide image in SU and then render out a 3000px wide image in VfSU they match, no problem. as it indeed, I was wondering if there is a vertical correction for the camera as in 3d max vertical correction at a vray camera or Guess vert, I've tried 2 point perspective but it changes the camera position and if I move it back the perspective changes . so my question is: is it posible to correct verticals (easy way) without moving my view?

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

Thank you! How simple!

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.

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.

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

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.

@valerostudio said: You have USE COLOR AS TRANSPARENCY ticked on. Turn that off. I would also load a glass vismat from the Chaos site, something with reflection and refraction. That suggestion is useful.

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.

Are you using DR spawners?

U think you should purge your model and then your layers, move it all on 1. Well it kinda helps.. : )

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.

I second that. Currently you cannot use emissive materials as lighting (like some other engines), just lighting effect, like a TV screen. You must light your scene with omni, spot, IES, dome. rect lights. An interior like this would need a combination of these.

@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

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.

@eidam655 said: Ted, are you sure that changing the Fresnel to ridiculous value is the real solution here? i'd be more concerned with the environment settings and their multipliers, and also the lighting used. larszzz, if you posted a screenshot (of the render and/or environment settings), that would be immensely helpful. Not knowing anything about a users scene, yes, changing the Fresnel IOR is what I would change initially. 3 is a good number to start with for highly reflective glass material, not ridiculous at all. You work back from there to get less reflection as needed.

@emn said: I guess, because the glass panels are situatied behind each other, the computer keeps reflecting the scene indefinitely. Is there a way to tell vray to reflect all the objects in the scene 1 time instead indefinitely. Forgot to say - you can set how many times the glass reflects/ refracts with the "refraction max depth" setting. In global settings, you also can set "Max transp levels" and a refraction override.
