Turning on Sharpen/Blur in VFB darkens the image or makes it completely black

[Alex_M]

If the denoiser is used, turning on the Sharpen/Blur layer only darkens the image. If the denoiser layer is turned off, the image becomes completely black when Sharpen/Blur is on. Please see screenshots below.

I also get glitches like these:

Hi Alex. We were not able to reproduce this issue in our environment. Could you send us your scene to https://support.chaos.com/hc/en-us/requests/new so we can have a look. Also are you using V-ray CPU or V-Ray GPU? What are the steps to reproduce this issue?

Hi Vladimir,

I've just submitted a ticket (ID #12033) that includes the scene. I am using Vray GPU. The steps to reproduce are in the ticket, but I'll list them here too:

1. Start rendering from the camera at 4000x4000 px resolution.
2. Wait until the Denoise layer automatically turns on. After the Denoise layer turns on, click on the "Calculate Sharpen/Blur" checkbox in the Sharpen/Blur layer.
3. The upper part of the image glitches or the whole image gets darker.

I hope this helps! Let me know if you have any other questions.
