Hi

Do you have any tips when rendering sheer curtains? I am not too worried about the curtains themselves (I used the Corona library preset) more about how they affect the scene. It used to be good practice with Mental Ray and Vray to render them separately and composite them in post.
Is light shining through sheer curtains affecting the scene negatively (noise etc...)?

I am happy to hear your tips on the subject.

Thank you.

If curtain blocks most of the light that's coming to a room, then indeed it can negatively impact render performance. Luckily, in Corona there's no need to render twice to exclude curtain from affecting the lighting. You can do this by assigning rayswitch material to the curtain and plugging your old curtain material to all its slots, except GI. You can read more about rayswitch and its uses here: https://support.corona-renderer.com/hc/en-us/articles/4402649577105-Corona-Ray-Switch-Material-and-Map
