Black Renders with Fstorm Render

Hello everyone.

We are now trying pulze for the first time and so far looks amazing.
We are having one issue, some renders come black (no aparent errors)
On the same file, some images come good and the others black. (4 out of 10)
We tryed to render them again and second time was good.

We are using Fstorm render.

Any idea why this happens?
Thank you in advance


I would like to kindly ask you to contact us directly via
We might need a log file to check what is happening. On the PC, once it renders black image, go to the settings (little cogwheel icon) and hit the “Collect Logs” button. It will create a zip file. Please send over that one to us.
Thank you in advance for your help.
Best regards,
