NACC(Non-Associated Cam-Clay) Material Node add NACC 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.

NACC Density:
Defines density of NACC surface/inside.

use Density Map:
When checked, use texture variation.

Density Map Var:
Defines density variation of NACC by texture map(Black = 0.0 / White = value).

Poisson’s ratio:
Defines material of the NACC. Smaller value get more softer. Larger value get more harder.

use Poisson Map:
When checked, use texture variation.

Poisson Map Var:
Defines poisson’s ratio variation by texture map(Black = 0.0 / White = value).

Young’s Module:
Defines material of the NACC. Smaller value get more softer. Larger value get more harder.

use Young Map:
When checked, use texture variation.

Young Map Var:
Defines young’s module variation by texture map(Black = 0.0 / White = value).

xi:
Defines material of the NACC. Smaller value get more softer. Larger value get more elastic.

use xi Map:
When checked, use texture variation.

xi Map Var:
Defines xi variation by texture map(Black = 0.0 / White = value).

Beta:
Defines material of the NACC. Smaller value get more softer. Larger value get more harder.

use Beta Map:
When checked, use texture variation.

Beta Map Var:
Defines beta variation by texture map(Black = 0.0 / White = value).

Friction angle:
Defines material of the NACC. Smaller value cannnot keep more retain its shape. Larger value get more breaks when it tries to retain its shape.

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).

Hardness:
Defines material of the NACC. Smaller value get more softer. Larger value get more harder.

use Hardness Map:
When checked, use texture variation.

Hardness Map Var:
Defines hardness variation by texture map(Black = 0.0 / White = value).

Texture Map:
When expose switch and connect map helper, multiply map intensity to NACC material.
And select map type “2D map” or “3D map”. For 2D map, you need to have UVW channel on input.
