Men-man

In this example, we want to simulate a big group of dynamic agents attached and move along with the humanoid giant.

Workflow

• Prepare a humanoid giant model, simple skin it and animate it. Notice the ratio between the giant and the crowd character.

• Give it the average UV, this is the preparation for the follicle creation.
• Create the hair on the giant, by selecting the faces of the object and then click create hair, like below method:

_{Select the faces > modify the option (At selected points/faces) > select the hair > delete hair and leave the follicles}

• Get the number of follicle, and create an arbitrary place node and make the agent number the same as follicle (get the follicles number by a simple python)

• Parent all of these agents onto the follicles

• This script is parent all agent onto each of the follicle, and set translate 0 means we put the local transformation of each agent 0 and put them to follicles

• But in above picture, you can see the agents are all standing there and no interesting. We need them lay down and randomized their orientations.
• You can deplace all agents and re-place them again, and run the script again by modifying some of the randomize translate

• Now the result can be more randomize instead of standing man.

• Repeat above steps, we can even make each follicle contain more than 1 agent, and the result can be higher density.
• In our test, 3 agents in each follicle can be get the best result and performance.
• Important Note: please modify the code and make sure each agent has some distance, so that the won't collide each other

• Return back to the 1st frame, and then select all agents, run inverse placement (Miarmy > Placement > Inverse Placement). We will get a new place node from agent positions and orientaions.

• Turn off auto avoid option (which we auto enable this option from version 5.1) 

• Go to 1st frame and place agents, you can see below result

• Create a logic which make our gents enable dynamics after 5th frame:
  1. scene Info > current frame
  2. dynamics > enable body dynamics
• Important Notice: we need to setup the agent dynamics body very good before running the dynamics

• Find a pose and render it as you with.
