From After Effects I export sprites in png format, the glow effect is also inside png. They look good. But in UE, it looks like in the video. Everything is blurring. How to fix it correctly? Please help me!
the default base material for sprites is a masked material.
go find the material. its named DefaultSpriteMaterial. duplicate it. edit your material and change from masked to transluscent. replace the sprite material with the one you created.
