Hello, I'm using a cylinder light and cannot make it double sided.

I've found and un-checked the 'Single Sided' switch on the Karma tab of the light with no result.

Is there something else I'm missing?

Setting its render visibility to primary will mean it won't cast shadows, but will still receive shadows.

Right! So it does. I was getting very mixed up, as I had already tried this, but what I was actually seeing was shadowing from an overall very soft dome light. I assumed this was shadowing coming from the ground object itself.

Thanks for clearing this up for me!

Or -shadow also works if you want it visible in indirect See render visibility here: https://www.sidefx.com/docs/houdini/props/karma.html [www.sidefx.com]

This is also a super handy page of info, not just for the shadow tips. Cheers!

I have a large, noisy shaped ground plane that includes lumps, walls etc. all in one combined mesh.

I'd like to receive shadows on this object, but not cast or catch shadows from itself. Is this possible with light path expressions, or render geometry settings?
