This plugin is a combination of particle system and slate, supports sprite and ribbon data type. You can use most of the modules of particle system, they'll be rendered directly in Slate without render target.

Just edit a particle system in Cascade Particle Editor, choose a UI material, then put it on UI in UMG Editor.

Additional Notes:

  • It is a new implementation for the rendering modules of Cascade ParticleSystem, rendered as a UMG widget.
  • It technically supports version 4.18~4.25, but only built under 4.23, 4.24 and 4.25.
  • Because of the limited Instancing support of Slate, the particles are rendered directly without instancing. That is why mesh rendering is not valid.
  • Only Camera-Facing orientation is implemented for Ribbon particles because I thought it was enough.
  • This plugin is designed to avoid using of RenderTargets. So NEITHER GPUParticles NOR Posteffects are supported. If you need bloom, you should use a RenderTarget with a ParticleSystem spawned in the world instead of this plugin.
