Particle System/Group – place here Particle Geometry Group.
Mesh – the mesh that will be instanced.
Render Type – you can choose the following render type:
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.
