Sand Material Node add sand material data to the emitter particles.
Input / Emitter Particles:
Input emitter for simulation. You must connect this input for work.
Output / Simulation Data:
output result simulation data.
Sand Density:
Defines density of sand.
use Density Map:
When checked, use texture variation.
Density Map Var:
Defines density variation of sand by texture map(Black = 0.0 / White = value).
Cohesion:
Defines material of the sand. Smaller value get more powdery(sand). Larger value get more chunky(soil).
use Cohesion Map:
When checked, use texture variation.
Cohesion Map Var:
Defines cohesion variation by texture map(Black = 0.0 / White = value).
Friction angle:
Defines material of the sand. Determines the angle of sand deposition.
use Friction angle Map:
When checked, use texture variation.
Friction angle Map Var:
Defines friction angle variation by texture map(Black = 0.0 / White = value).
Beta:
Defines material of the sand. Smaller value get more decompress. Larger value get more compressed.
use Beta Map:
When checked, use texture variation.
Beta Map Var:
Defines Beta variation by texture map(Black = 0.0 / White = value).
Texture Map:
When expose switch and connect map helper, multiply map intensity to sand material.
And select map type “2D map” or “3D map”. For 2D map, you need to have UVW channel on input.
