i have an old project, which i want to port to android. it uses old unity version with post processing behaviour and it works fine there, but there’s an issue. old unity versions have their allocator broken on new android versions, which results in huge memleaks and crashes on lots of devices. i tried to switch to newest lts version of unity, which have no more allocator issues and everything works good in editor, but if i make a build and run it, then there are post process glitches like bloom being black in very lit places, fog being messed up and overlit. after that i searched a bit and found out that after unity 2018 post process behaviour do not work anymore. i tried to switch to the oldest available version of unity that have allocator fix, but unfortunately it has post process behaviour broken too. then i tried to use new post process stack to replace the post process behaviour, but it seems impossible to reproduce the chromatic abberation, bloom and grain effects i had with behaviour, no matter how i was trying to do that, i was just going circles, a lot of parameters that were there in behaviour are now missing. i am caught between the allocator from older versions and broken post process from new versions. is there any way i can possibly fix the post process behaviour library and use it with new versions of unity? or is there any other solution?
