[Official] Particle System [Shuriken] Improvements

Something I get asked a lot from my asset store customers is “How can I make particles work in the UI Canvas?”. They talk about using particles to make buttons glow or catch fire, or emit confetti over win screens on mobile games.

Is there a recommended way to utilize particles for UI?

Some workarounds I found mentioned camera layering/stacking or using a hacked or custom shader to have particles render in the UI Canvas.

Maybe it could be an option in the Standard Particle Shader to have them render in the UI Canvas?

We have some scripting API which can be used to add particles to UI.
The problem is that the UI generates its own mesh which is then used to render, so in order to be part of the UI the particles must become part of that UI Mesh, a shader would not do this. We provide a BakeMesh api which lets you get a Mesh version of the particle system which can then be fed into the UI.
This is the best solution I am aware of that uses this api https://github.com/mob-sakai/ParticleEffectForUGUI

We have done some work internally to find a solution, something that is still ongoing(No ETA im afraid).
