I have recently asked a question where I wanted to know why Post Processing effects lag so much on mobile. As I know now, it has to do with limited performance on mobile end devices.
So, I am asking if there is any website or app where you can apply bloom effect to the texture you want to bloom, so that it does not have to be redrawn every frame, but is rather set directly in the texture.
UPDATE:
Also as a comment pointed out that I could use photoshop:
This is no option for me because I don’t have photoshop installed and don’t want to pay for it… I only have Krita that worked fine for drawing simple assets but I think it can’t add bloom.
