Hi,
So far I was not able to reproduce this issue. I rendered the scene 20 times and each time it rendered correctly..
Do you get any warning or error messages during rendering?

Hi Rowan,
Yesterday everything worked fine for me as well but 2 days ago I had parsing time slow down and then the objects disappeared from the render twice! This is the reason why I opened the post here again. I had no warnings or errors at all. Only slow parsing time which wasn't as slow as before the fix we are using now. Just a bit slower than normal.
Yesterday I did a lot of tests and previews on that scene and me too as you, no issues. -.-
At this point I want to report something but I don't want to complicate things, just for you to know.
A month ago I decided to start using the Substance materials and as you probably know, we have 2 ways to use them:
1. Via the Substance plugin.
2. By exporting from Substance SW all the maps and build each shader manually.
My experience:
1. A disaster! A lot of crashes, very often the plugin was resetting the parameters and then guess what? Object with displacement were disappeared very very often from the scene.
I naturally thought that this issue was related to the plugin itself and not to Corona or 3ds Max 2021.
2. Transforming the parametric materials in maps then manually created the shaders and had no issues at all.
So, this behavior I saw twice the other day really surprises me as there are NO SUBSTANCE parametric materials at all in the scene. Since I had those problems I never used them again. I just use their maps (which I like) but not their native shaders.
Let's keep in touch, I have a lot of work to do these days so I'll have more change to check if this behavior turns back or not and figure out when.
For now I have no more clues.
Thanks for helping as always.
Thanks!
