Title: propagate masks not working as expected with CGeometry_Zdepth and reflection
Post by: genesys on 2021-08-16, 13:43:53

https://coronarenderer.freshdesk.com/support/solutions/articles/12000066916-how-to-use-masks-with-reflection-refraction states that CGeometry_Zdepth should be working with propagate masks. However, when I create a mirror and set the mirror material's propagate masks to 'through reflection', I still get the distance of the mirror surface instead of the distance of the reflection in the CGeometry_Zdepth output.

Using corona 6.

Hi, support for CGeometry_Zdepth was implemented at a later date for a daily build of Corona Renderer version 7 https://forum.corona-renderer.com/index.php?topic=30876.msg183142#msg183142, thank you for pointing this out we will update the article to reflect this information better.

You can find the latest version here: https://corona-renderer.com/download

@genesys - is this what you are reporting? (see the attached image)

What happens: the reflection of the teapot is "colored" the same as the teapot itself.
What you expect: the teapot itself would be bright as it is, but the reflection should be black (because it is far away from the camera).

Do I understand you correctly?

This is fixed, and the updated version of Corona will be available soon!
(the reflection will appear correctly in the Z-Depth pass - just as if actual geometry was placed in the same distance from the camera as the reflection)

Hi,

This is fixed and available in the latest daily build. You can find it here: https://forum.corona-renderer.com/index.php?topic=33839.msg194990#msg194990
