Lights issue

[Sean_Williamson]

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?

For help, could you share us more information?

Especially lights' and glass parameters.

Hi,

This looks the same as some previously reported topics.

Please see this topic for a workaround: https://forum.corona-renderer.com/index.php?topic=16542.msg124916#msg124916

Thanks,

Not sure if its Corona 4 but i never had this issue with Corona 3.

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

[Sean_Williamson]

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

[James Vella]

have you tried turning 'visible in refractions' on?

[Sean_Williamson]

Yes tried turning it on and off, makes no difference.

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.
