UPDATE: Current documentation: Particle Editor Extension by Cultrarius
Hey,
I have created a code plugin to extend the particle editor (Cascade) with completely new modules. I would like to know if any of you are interested in such a plugin?
Furthermore, if you have any ideas/wishes for new modules you can post them as well 
Demo video:
Here is what the plugin includes to far:
- Custom Logic: implement your own particle effect logic for position, velocity or color in C++ or blueprints!
- Mesh Location: spawn particles on the surface or vertices of a static meshes (without having to use sockets). New! Also supports dynamic meshes (if you can provide triangle data at runtime).
- Spiral Location: spawn particles on a spiral path to create galaxies (see screenshot)
- Heightmap Location: Use a custom texture to determine the particle height
- Texture Pixel Color: (CPU only) Use a custom texture to determine the particle color
- Donut Location: A new shape (like the sphere or cylinder) to spawn particles in
- Jiggle Location: (CPU only) Makes particles jump around a bit each tick, very useful to make e.g. insect swarms ort magic effects
- Swarm Movement: (CPU only) let the particles behave like a swarm by using a flocking algorithm
- Turbulence: (CPU only) a quick way to add turbulence similar to a vector field to (using 3d curl noise).
- Translucency Sort Order
- Particle Decals
