I have the same issues in my project with ACES and URP. Did you manage to fix this? Weirdly enough I think it might be hardware specific since the same project on different PCs I have tried has the same issue. I have a fresh Windows Install and still no fix
Something to keep in mind in relation to Unity’s ACES implementation is that they are using ACES v1.0, which has a variety of issues that have been addressed since it’s initial release and is currently on ACES v2.0. It would be a good idea for Unity to update the ACES.hlsl file to make it match with the modern implementations of ACES along with the other fixes many in the ACES community have made to address the other issues.
I’ve recently just started having this problem when I changed the build to android from windows.
Have you found a solution?
