I’m having a really hard time getting satisfying/expected results rendering in Create 2022.1.4.
Problem 1: The very first frame I render after I start the application is always completley black. Doesn’t matter which rendering mode, doesn’t matter wether it’s a still frame or a sequence.
Part 2 of that problem (and I’m not a 100% sure these are connected): every first frame after that, seems to be some kind of weird blend of the last rendered frame and the current one. This affects seemingly only the first frame of a new render job and is especially noticeable when switching to a new rendering mode.
Problem 2: Weird horizontal lines artifacts specifically when using Iray
These lines also appear in interior scenes/across meshes; so it’s not an issue with the sky. I sadly can’t show other parts/pictures from my project for NDA reasons.
I’ve tested a bunch in my own scene with render settings etc to no avail. Then I decided to load up the Attic sample scene and just render out one image with default settings.
I rendered the opening shot 4 times back to back, here are the results:
The render always looks fine/as expected in the viewport preview, and I am able to generate the expected results here and there. It just seems I get a different result everytime I press the render button.
Now to my specs:
RTX A5000 Laptop GPU
2x RTX A6000 EGPU
GPU Driver: 516.59
I did also try using only my integrated RTX A5000 GPU.
I also tried the recommended GPU driver 471.41
Input/advice would be greatly appreciated.
