Particle System/Group – place here Particle Geometry Group.

Mesh – the mesh that will be instanced.

Render Type – you can choose the following render type:

  • Multipoints
  • Multistreak
  • Points
  • Spheres
  • Sprites
  • Streak

Sprite width – the width of sprite particles in world units.

Sprite height – the height of sprite particles in world units.

Sprite twist – the twist of sprite particles in degrees.

Sprite orientation – type of sprite orientation.

  • towards the camera center
  • parallel to the camera plane

Point Size – The size of point and multipoint particles.

Use Radii as Point Size  – the point size will be taken form radii parameter.

Point Size is the world space –  the point size is in world space, not screen space

MultiParticles Count – The number of particles generated for each input particle, when the render type is multipoints or multistreaks.

MultiParticles Radius – The maximum distance between the original and a generated particle when the render type is multipoints or multistreaks.

Line Width – the width of streak particles.

Tail Length – the length of streak particles, in world units, the actual length depends on the particle velocity as well.

Primary visibility – If off, shading an intersection with this mesh will not generate a gbuffer.
