SUMMARY
>From KA topic
https://krita-artists.org/t/animation-frame-rendering-clones-limit-render-in-failure/25029?u=grum999
Everyone is not able to reproduce problem, I don't know why.
But we are at least 2, on 3 different computer, to have the problem.
In synthesis, using too much CPU to render some animation generate a "render in
failure"
STEPS TO REPRODUCE
Download attached krita document
1. Using document "as provided"
When using 19 to 24 CPU to render animation, it’s systematically in failure
after few frames has been rendered.
When using 18 or less CPU to render animation, it’s sometimes in failure (it
occurs, but it’s not systematically - so harder to reproduce)
2. Delete layers “Blur + Pixelize” and “Halftone test”
Rendering with 24CPU is most of time complete.
But sometime it stop before the end (598 of 600 frames rendered for example)
This case is really hard to reproduce systematically.
Using less CPU (4 for example) render is complete.
Can’t say it will always work: I just can suppose that frequency of failure
might be so low in this configuration that it will practically never occurs
3. Delete layers “Blur + Pixelize” and “No filter”
When using 19 to 24 CPU to render animation, it’s in failure after few frames
has been rendered
When using 18 or less CPU to render animation, it’s sometimes in failure (it
occurs, but it’s not systematically - so harder to reproduce)
OBSERVED RESULT
See explanation in step to reproduce section
EXPECTED RESULT
Rendering animation should be complete whatever the number of CPU is used
