VRAY GPU bucket vs progressive

[anto3d79]

I have an issue when using bicket mode in VRAY GPU RTX.

some buket turn out black with this message error : Error : [VUtils::VOptix::OptixPipelineWrapper::launch] 7050: OptiX error encountered in vray_optix7.cpp[320]. Error Code 7050

instead in progressive mode everything is fine working great with both gpus.

Hello anto3d79,

Do you experience this issue with any scene or a specific scene only? Can you specify the exact versions of V-Ray and Cinema4D that you have installed? What are your GPU model and GPU driver? Please note that the recommended NVIDIA driver for V-Ray GPU is version 497.09 as stated here. If you are using a different driver from the recommended one, please install driver 497.09 and see if it helps.

Is the issue happening only in RTX mode? What about CUDA? Have you tried monitoring your VRAM usage to see if you have enough memory to render the scene? You can check that through third-party software such as GPU-Z. Please let me know what are the results of your tests.

Thank you.

Hello anto3d79,

Thank you for the info.

Would you mind downgrading to the latest recommended NVIDIA driver for V-Ray GPU rendering (version 497.09) and let me know if you still experience this issue? Thank you.

The recommended GPU driver can be found on NVIDIA's website. Here is a link to the driver. Alternatively, you can contact NVIDIA for more information.

Please let me know if using the recommended driver for V-Ray GPU rendering helps.
