Sorry but no... I tried with the file you provided, but came to the same conclusion as you, use a 17mm focal length override.

thank you for help anyway.. 😄

Sometimes when creating new materials a disconnect can occur between V-Ray and Sketchup. Try Going to Plugins> Debugging> Force Sync All Materials

thanks, Andybot. I had been putting it in the wrong spot... in fact, you made me realize I've been tweaking the parameters on my fresnel reflections wrong, until now! No wonder it felt like such a guess & check process to get the results I wanted...

sure, it's possible if you're on the same computer. If you only have one license you can only use one computer at a time. You may also be able to set processor affinity so you reserve some cores of one session, and other cores for the other session. (since vray uses all available cores to render, it may be pretty slow to run two renderings at the same time.)

That looks like low sampling of Irradiance Map. Put higher values (go from 50/20 to something like 80/40)

will try that setting. Thanks for the help!

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.

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.

Thanks Rob, nice tip!

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

try running the rendering with the glass dome hidden. Maybe do a material override render too. Something is not right with your GI calculation.

yes, try updating to the latest release. Do be aware that the demo also limits you to only few lights rendering at a time.

Are you running a trial version?

that's the likely explanation, resolution is limited in the trial version. You also get the lovely watermark on your image.

Thanks Andybot! you helped me a lot.

I assume it will be available very soon. I have nightly access and have tested it.

Thanks!

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 😄

Like this!!!!! Thanks . Hope vray 3.0 comes out soon with fur and more feature !

^^ 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.
