We upgraded from 4.16 to 4.19 and several of my particles are now way brighter or thicker
I ve gone through the version notes and havent found any clues as to why. More so just curious so I know what change Im working with for the future or what other effects I should look into changing because of this change
I cant really roll the project back but i can show you an approximate look. How they looked after the upgrade and what i tweaked them down to to look like they did before approximately
you might want to look into ue4 tonemapper. they changed it and its bloom.
The first few hits of this: ue4 tonemapper - Google Search should give you some info about it.
I am guessing this is whats resulting in the different look.
