From Miarmy 4.5 we support v-ray user attribute and additionally, we added some syntax so that you can randomize the attribute on demond.

Workflow

• Select the object in the Original Agent Structure Geometry_?

• Adding the user attribute

• Fill the attribute (string) in the attribute editor

Reference

Rule 1

Keyword: RAND[x, y]

Example:

test=6;test_color=RAND[1,5],RAND[1,5],RAND[1,5];

Result:
user_attributes="test=6;test_color=1,3,2;"
user_attributes="test=6;test_color=3,4,2;"
user_attributes="test=6;test_color=1,4,3;"
...

Rule 2

Keyword: RAND<x, y>

Example:

test=6;test_color=RAND<1,5>,RAND<1,5>,RAND<1,5>;

Result:
user_attributes="test=6;test_color=1,1,1;"
user_attributes="test=6;test_color=3,3,3;"
user_attributes="test=6;test_color=2,2,2;"
...

Rule 3

Keyword: AGENTID

Example:

test=6;agentID=AGENTID;

Result:
test=6;agentID=3;

Rule 4

Keyword: RAND_RGB_AGENT

Example:

test=6;test_color=RAND_RGB_AGENT;

Result:

test=6;test_color=0.31,0.54,0.13;
test=6;test_color=0.31,0.54,0.13;
test=6;test_color=0.31,0.54,0.13;

Rule 5

Keyword: RAND_RGB_OBJ

Example:

test=6;test_color=RAND_RGB_OBJ;

Result:
test=6;test_color=0.31,0.54,0.13;
test=6;test_color=0.24,0.32,0.83;
test=6;test_color=0.32,0.69,0.98;
