KtoA - ArnoldSceneBake doesn't work?

Hi,


I've unsuccessfully tried to use the really useful new ArnoldSceneBake node in Katana. On adding to the node graph and clicking scene export, just the bake process started message shows up without any change in the render log or any output files generated.

Tested on a simple scene with one primitive with a monolithic standard surface assigned and a physical sky dome light. Tried exporting as ASS and USD.

Screenshot and file attached.

Not sure where I'm going wrong.

Any help appreciated (maybe a working sample test file).


Thanks!

Hi!


Sorry about the lack of answers for this long, we missed this question completely.


I was able to reproduce the issue with the latest release. A quick workaround is to save the katana file and reopen the scene. For some reason, the ArnoldSceneBake is not initialized correctly for the first time and only works for the second. Our testsuite didn't catch this issue, as we just reopen already saved files, but don't create the ArnoldSceneBake node on the fly.


I'll let you know if I find anything.


Cheers,

Pal.

Hi Pal,

Thanks for following up.

I'll follow the workaround going forward.


Thank you

For some reason the "Export Scene" button isn't working, but if you run

NodegraphAPI.GetNode('ArnoldSceneBake').bake()

it works.


Hope that helps

Hi Liam,

Thanks for the hint.

Guess we'll use the NodegraphAPI for this.
