2D Portals VFX

Hey! I'm drawing this visual effect idea!
I start with FBF (frame-by-frame) sketch animation in Procreate, then use Photoshop for some effects, and finally export it to Unity 3D. In the engine I mix the animation with some particle system.

Here's another attempt. I'll tried to do some CHAOS version, probably need more things (or less, I don't know)

In this week I did different ideas, testing different thing but in the same style. I'm trying to improve in using my pencil more freely :)

Still testing the mix between Procedural FX with Unity Particle System and animations exported as a Procreate sprite sheet. Shapes, Dust, Ground and more. But I think I'm getting closer to want I want (or can do)

Hey! I'm drawing this visual effect idea, about 2D Portals!
I start with FBF (frame-by-frame) sketch animation in Procreate or Adobe Animate, then use Photoshop for some effects or shadows (but that's in the final process), and finally export it to Unity 3D. I use the animations as a Spritesheet In the engine and I mix it with some particle system. Sometimes, if I'm going to work in Universal Render Pipeline I use a shader for the Glow.
