Title: Lights issue
Post by: Sean_Williamson on 2019-06-26, 11:18:49

I am using Corona 4 for 3DS Max and have an issue with Corona lights through glass.
As you can see, the lights appear black when they are behind glass materials.
The glass is the from the corona materials library.
Has anybody else had this issue?

Especially lights' and glass parameters.

hmmmmm, Is 'visible in refractions' turned off with 'occlude other lights' turned on, in your light's visibility settings?

Light settings attached.
When i turn off the IES it seems to be fine.
I am using one of the preset Corona IES.

See rowmanns' post, the workarounds are already there in the threads he links to (and those are the only workarounds - as the linked threads note, this is a known issue with Corona Lights with any sort of directionality, which means either Directionality, or IES).

Thanks everyone.
Hopefully this will be sorted in the future.
I'll just Photoshop the lights in.
