H to A Mesh lights broken

cherylling4B7JM · ‎02-10-2021

Mesh lights have stopped working in H to A 5.5.0.2 - arnold 6,1.0.1

I'm repeated getting an error stating 'expected exactly one mesh' I've tested with basic primitive shapes (box, torus, etc) and it's the same result.

Not really an option to upgrade to 6.2 right now. does anyone have a workaround? I've uploaded a log file here:

So far the only way I can repro is to disable the light, then restart the Render View.

Then, to get the light working again after I re-enable it, I have to restart the Render View again.
