Hi, I just upgraded my video card to a EVGA GTX 780 Ti and was excited to test out Vray RT using CUDA on it. Unfortunately my first tests had some strange results. CPU RT mode looked fine. CUDA mode however…I attached an image that contains all relevant information.
OS: Windows 7 Home Premium
Maya version: 2015 (same problem with 2014)
Vray Version: Beta 3.05.03
The GPU specs and my video driver information are in the attached image.
Thanks
Hi,
Would it be possible to send us the scene file ? The GPU render result looks completely wrong and we have to find the reason for this.
Please archive the Maya file along with all textures and send request for FTP access to our support@chaosgroup.com mail or just send us a download link to the file on the same mail.
Thank you very much.
Hi,
It turned out that the main problem comes from the secondary GI engine, which is Light cache. It is still under development and may not work well.
Use of Brute force/Brute force primary and secondary engines is recommended for this case.
