RT GPU Mode not rendering the lights correctly.

[johannpascual]

Hello, peeps!

I need help... maybe someone has experience on my problem. I posted this in the SU section but then I just saw this RT section.

Here are my specs:

Intel i7 - 4770K
Gigabyte z97x-ud3h
8gb RAM
nVidia GTX 770 2gb - latest drivers (335.23)

Windows 7 Ultimate - latest updates
SketchUp 2013 Pro
Vray v2.0 sp1

RT is fine with CPU mode. Stable and no problems. But when I use GPU CUDA, it doesn't render the lights. Please see attached.

Please help... I want to make use of my GPU to get my money's worth.

What kind of lights are they? What are their settings?

Best regards,
Vlado

Halo!

They are spotlights and emissive materials. Settings are just normal I guess... I tried ticking on and off the options that I see... but no effect.

But it doesn't matter which kind of light because all of them don't seem to work when I try to use GPU. All of them look like the one in the attached photo.

Would it be possible to send the scene or a part of it for investigation?
Thank you very much in advance.

Hello, all!

I have done screenshots for you all to see. I have placed all the files here.

Here are the specs:

1. iMac with GTX 680MX (OSX and Win7)
2. Windows 7 with GTX 770
3. SketchUp Pro 2013 and Vray 2.0 SP1
4. Latest Nvidia and Windows Drivers
5. For the RT settings, it's all default.

Notes:
1. For OSX, RT renders look right and you can change the light settings and it will refresh... but the moment you zoom in or change views, it crashes RT.
2. For Win7 on both machines, RT is stable and fast... apart from it not rendering lights correctly.
3. I updated to the latest nVidia drivers and the RT renders seemed to improve. The scene is now lit but the emission materials remain black.

NOTE: I am posting this in the SketchUp Bugs section too since I don't know where to really post it.
