[Unity Shader Graph] Episode 4: Dissolve effect
With just a finger snap, Thanos caused the extermination of half of all life in the universe. We saw Black Panther, Scarlet Witch and the friendly neighborhood SpiderMan vanish in the air, one by one. These iconic characters disappear from the screen with thousands of pieces. That's the DISSOLVING effect.
An enemy turns into multiple particles and becomes invisible when getting shot. A monster was summoned out of nowhere. These are also the DISSOLVING effects.
DISSOLVING is one of the most popular visual effects in Computer Graphics. And there are many ways to implement it in a game. Today I will show you my method, which relies heavily on the Alpha property.
