[SOLVED]Single State Crowd Possible?

[Atom]

Hi All,

 

I am trying to help out Carlo_C with his crowd problem and I ran into something I could not solve myself. Using his FBX (located here: http://forums.odforce.net/topic/23560-3ds-max-biped-to-crowd-agent/)I have a single biped walking. So I go through the steps of...

 

1.) Import FBX.

2.) Create Bake Agent (shelf tool)

3.) Bake the agent and yes the files are created.

4.) Populate to generate a crowd_source node (shelf tool).

5.) Simulate to generate the default simulation using the crowd_source. (shelf tool)

 

This kind of works but the default simulation contains two states, walk and stand. I just want walk.

When I play the simulation my walk starts to happen but then everything starts scooting because I don't have a stand state.

 

I thought I could just disconnect the unwanted states and transitions but then the solver no longer works. I also thought...well I will just rename the stand to walk for both state and transition but this no longer works either and actually cause Houdini to graphically glitch out and become unusable.

 

So I guess I'll just ask the question. Can I have a single state crowd system or do I always need two states for the solver to work correctly?

 

I am attaching my setup HIP file. You can fetch the FBX from Carlo's link mentioned above if you want to try this out.

we're always interested in seeing any strange files.

After watching Peter Quints new Vimeo tutorial on the crowd system I think I have figured it out.

 

And YES, you can use a single agent with only one state. The problem, of course, was configuring the crowd_source node correctly.

 

I am attaching the fixed scene along with the baked out agent folder.

Atom thanks so much for your help, after watching the Peter Quint video and looking at your file it all made sense and I was able to get it working! From your example it looks like the sticking point was a combination of the FBX import and getting the agent to bake out properly. Changing the FBX import setting fixed the error I was getting. Also knowing what to configure on the crowdsource node!

 

Time to save out some more states for this test guy and see if I can get a crowd sim working in a simple production scene. Once again thanks for the help Atom it's massively appreciated!!
