[Max] I need help! / ies wireframe not showing for Corona Light

« on: 2025-02-14, 04:09:12 »

Hi everyone, I have a question about Corona Light. I remember a few years back when I was still using older versions of 3ds Max and Corona Renderer, I can see the yellow ies wireframe in the viewport (1st image) , but now the yellow ies wireframe is not visible anymore (2nd image). Currently I am using 3ds Max 2023 and Corona 10. Does anyone know if this is a new update or a bug? Is it a 3ds Max issue or is it a Corona Renderer issue? Thank you.

It would be really convenient to have the wireframe so it's easier to look for the lights in the viewport, and to differentiate between different ies files.

Thank you for the helpful tips! That would be very useful in larger scenes with lots of objects :)

Ah okay :) I tried including the glass and mirror only and the result turned out weird, so I selected everything in the scene and included them (don't know if that's the right way to do it?) and it worked! Thank you very much.

I tried using CMasking_ID and it worked :) CMasking_Mask still shows a black screen though. Just curious, how do I "include objects in the CMasking render element settings"? Maybe I can get the CMasking_Mask to work that way.

Hi, I tried adding a CMasking_Map render element and going to Interactive Render to try it out, but it's showing just a black screen. Is there a step I missed?

Here's what I did. I changed the "Propagate Masks" to "Always" for the clear window glass material and the mirror material. But the alpha is still not showing in the mirror reflection. Am I doing something wrong? I tried "Through Reflection" and "Through Refraction" options as well but nothing changed either.

Hi guys, does anyone know how to get alpha channel from mirror reflection? Or saving a render as a .png file and retaining the window's transparency in the mirror?

I read a post about a similar problem here:
https://forum.corona-renderer.com/index.php?topic=39199.0
but I still couldn't figure it out. Propagate Masks didn't work for me.

Here I have a sample scene of a window and a mirror. I will be saving this render as a .png file so I can insert my own background outside the window, but I am unable to do so with the mirror reflection. Can anyone help me? :) Thank you so much.
