I’ve got a simple scene, open plan area, lit by a simple dome light.
I’ve got no ceiling, just two walls, and a floor and some construction products (flooring).
I applied Hue/Sat with Cryptomatte on the walls/floor and floor joists - renders just as I like it.
I then hide a couple of simple items and unhide another couple of simple items and my Cryptomatted Layer Adjustments are not being applied…
How?
I cannot give the client two images with inconsistent looking walls and floors/floor joists.
And this is not an issue regarding color bleeding etc - it’s a Layer Adjustment / Cryptomatte issue (it appears).
I’m on V-Ray 5 the 3.2 and this is GPU rendering.
Tried merging into an empty new scene - made no difference…
Instead of creating, I was program solving - got nothing done…

Okay, this happens only in GPU rendering, not in CPU rendering.
I guess Chaos don’t support questions relating to previous versions of software bugs?
My concern is will this still be an issue if I upgrade to V-Ray 6

Okay, I purchased V-Ray 6 and this still happens.
What do I now do?
Open a support ticket?
Maybe I don’t understand how Cryptomattes work but surely if I all have is 2 walls and a floor, and I have a sofa in the middle of an empty room but I have applied Cryptomatted Layer Adjustments to the walls, when I swap out the sofa for a table, the walls should still have their cryptomatted layer adjustments applied?
This is ONLY happening in GPU rendering.
Are you re-rendering after unhinding geometry? I can’t seem to reproduce the issue. Please provide a video reproduction if possible.

Sorry, it was my bad…
It was because auto-exposure was set in the Render Dialog box…
(well, at least it prompted me to upgrade to V-Ray 6
)…
