GPU Lighting Cache

[ziyao_zhang]

Hi,

When I render an image, Vray gives me a warning about the GPU lighting cache. Does anybody know how to solve it? Thank you.

Dear ziyao_zhang, hello.

In order to be more helpful please provide us the following information:

• exact V-Ray version (screenshot of V-Ray > Help > About)
• exact Rhino version
• are you using CUDA or RTX render engine
• currently installed GPU driver version and Graphics card type
• is it happening in all scenes (even in newly created ones)
• have you noticed when the issue started to appear (were there any updates etc.)

Waiting for your answer.

Best regards,
TS

Hi, tsvetomira girginova

1. V-ray for rhino 7, 5.20.06
2. Rhino 7
3. I am using CUDA render engine
4. GUP diver version: 512.96
5. I am not sure about this, I used a random scene and interactive render.
6. When I start to render a random scene, the issue happened.

Thanks for the details.

Please be aware that on this page is listed which is the recommended driver version - now it is 512.59.
So, please downgrade to it and share is there a difference.

Are you able to perform a Production render (to confirm is it happening when performing Interactive only)?
If you open a new blank scene is Interactive running without errors?
Have you tried re-installing V-Ray?

We will need these details to pursue the issue further.

Hi,

I perform a production render, there is no error message. However, I have another problem. The cosmos does not load. I follow the instructions and download the latest version. I cannot find cb log in "...". Thank you.

Hi again,

let's solve Cosmos now.

First you could try this suggestion.
If the issue persists, we will need your cb.log & config.json (both located here: C:\Program Files\Common Files\ChaosGroup\ChaosCosmos).

Hi,

I try to stop and start the chaos cosmos, but it does not work, And I still cannot find cb.log and config.json

[tsvetomira.girginova]

Hi,

from the screenshot is seen that you are looking into a wrong direction.
As mentioned above, there are in C:\Program Files\Common Files\ChaosGroup\ChaosCosmos
Please don't miss Common Files (this is the difference).

I will open a ticket for you now, where you can send them.

[tsvetomira.girginova]

Now I saw that you already have an opened ticket ( #4034 ) from last night and Aneliya has answered you today.
Please continue the process there and let Cosmos bright up your work again.
