This plugin provide a component to render particle effect for uGUI in Unity 2018.2+.
The particle rendering is maskable and sortable, without Camera, RenderTexture or Canvas.

Description

This plugin uses new APIs MeshBake/MashTrailBake (added with Unity 2018.2) to render particles by CanvasRenderer. You can mask and sort particles for uGUI without Camera, RenderTexture, Canvas.

Compares this "Baking mesh" approach with the conventional approach:
(This scene is included in the package.)

Approach Good Bad Screenshot
Baking mesh
UIParticle		 Rendered as is.
Maskable.
Sortable.
Less objects.		 Requires Unity 2018.2+.
Requires UI shaders.
Do nothing Rendered as is. Looks like a glitch.
Not maskable.
Not sortable.
Convert particle to UIVertex
UIParticleSystem		 Maskable.
Sortable.
Less objects.		 Adjustment is difficult.
Requires UI shaders.
Difficult to adjust scale.
Force hierarchy scalling.
Simulation results are incorrect.
Trail, rotation of transform, time scaling are not supported.
Use Canvas to sort Rendered as is.
Sortable.		 You must to manage sorting orders.
Not maskable.
More batches.
Use RenderTexture Maskable.
Sortable.		 Requires Camera and RenderTexture.
Difficult to adjust position and size.
Quality depends on the RenderTexture's setting.





Demo

WebGL Demo





Usage

  1. Download ParticleForUGUI.unitypackage from Releases.
  2. Import the package into your Unity project. Select Import Package > Custom Package from the Assets menu.
  3. Add particle system to canvas.
  4. If you want to mask particles, set the "UI/UIAdditive" shader to material.
  5. Add UIParticle component to particle system from Add Component in inspector.
  6. Enjoy!
Requirement
  • Unity 2018.2+ (Tested in Unity 2018.2b9)
  • No other SDK are required





Development Note

BakeMesh API has a issue!

See this issue.

UIParticle avoids the issue, but the rendering result lags one frame.

Please vote the issue to improve UIParticle!
