I see that Arnold 5.2.0.1 has this in the release notes
7436 Toon Render: random issues with keylight initialization
I will try the new core and see if this fixes the random issues I had with the Toon shader.
I'm afraid the issue is still there so I'm keeping this open.
I tried and changed all AiBegin(GetSessionMode())
back to just AiBegin()
to see if there might be the new AtSessionMode set to AI_SESSION_INTERACTIVE that caused this but I still got the same bug with it set to AI_SESSION_BATCH.
@sjannuz Do you know if there are any more issues with this in the core that wasn't fixed with core ticket #7436?
Currently there is no open ticket about that. I'll try to reproduce it myself as well. Have you already tried things like using a single thread and such ?
I hadn't tried a single thread so I just did, and I had the same result. Just open up test 0267 and hit the Preview button. Refresh that several times and it's like a 50/50 chance that the stylized highlights will render correctly. I noticed that Texture search path is set on that test... So it might fail to find the texture on your machine. Will look in to that.
I just tried options.parallel_node_init false
with both a single thread and multi-thread but still have the same issue.
Issue still there with Arnold 5.2.1.0
I just heard from the core team that they also have a failing case, and they're working on fixing it.
Arnold 5.2.2.0 is out and has the same fix listed again:
7436 Toon Render: random issues with keylight initialization
But I'm sad to say that it still doesn't work in SItoA. @sjannuz Could you check with the core team?
Still having issues with this in Arnold 5.3.0.1
And still same issue with Arnold 5.4.0.0
Issue is still there in Arnold 6.0.1.0.
Issue still there in Arnold 6.0.2.0.
While doing #26 I noticed that the stylized highlights in the Toon shader doesn't render properly every time. I haven't been able to reproduce it in kick so it seems like it only happens in Softimage. This bug will cause test_0267 to fail randomly.
