Hello,

I ran into this issue where Labs simple baker sops dosent seem to work anymore from Houdini 20 onwards?

Every time I try to render or bake. This error message shows up.

Traceback (most recent call last):
File "labs::Sop/simple_baker::2.0/execute", line 1, in <module>
File "labs::Sop/simple_baker::2.0, PythonModule", line 6, in render
File "C:\PROGRA~1/SIDEEF~1/HOUDIN~1.547/houdini/python3.9libs\houpythonportion\ui.py", line 1137, in decorator

File "C:\PROGRA~1/SIDEEF~1/HOUDIN~1.547/houdini/python3.9libs\hou.py", line 78643, in render
return _hou.RopNode_render(self, *args, **kwargs)
hou.OperationFailed: The attempted operation failed.
Error: Error rendering child: /obj/anti_aging_device_v2/simple_baker1/ropnet1/rop_games_baker/single_bake

Any idea why? Any suggested solution would be much appreciated.

Sorry, I don't have solution for this but just wanted to say that I'm getting the same error when trying to use Simple Baker with Houdini v20.5.332. I have tested it on both PC and Mac version and can't get it to work on neither.

I really hope we can get answer soon.
Im not a very technical person but thinking logically, I do wonder if its something to do with mantra??

I mean mantra is slowly being made redundent and Karma will be the main render engine, I wonder if this is the cause of the issue as Houdini no longer support mantra and these baker HDA uses mantra setup?

Just guessing but I still have no clue why is it not working.

I submitted a bug report and got this reply:

Hello,

The simple baker is being deprecated in favour of the maps baker.
Please try using the maps baker instead.

Hey Jukkam,

Thanks for the update. At least we know now.

Cheers!
