Crowd - Randomize Heading does nothing

[dansidi]

Hi,

 

Can anyone explain how to use the Randomize Heading parameters on the Crowd Source?

They don't seem to have any effect at all.

I have set Velocity to zero, but still no luck yet.

 

Any assistance would be great.

 

Many thanks!

It works, you just have to solve it in order to see the result.

[dansidi]

vector look = set(fit01(rand(@ptnum), -1, 1),0,fit01(rand(@ptnum*23), -1, 1));
vector up = {0,1,0};

@orient = quaternion(maketransform(look, up));

matrix m = qconvert(@orient);

v@v = {0,0,1} * m;

So, my colleague gave me this voodoo to put in a wrangle BEFORE the Crowd Source node.

It does the job, but still leaves me wondering what the Randomize Heading parameters are for on the Crowd Source

It doesn't - I was solving the crowd and it wasn't doing anything.

Thanks for replying, though :o)

Maybe a problem with your build - I just tested it and it was working fine. Houdini 18.0.287

18.0.348 here.

Thanks for trying it.

It's obviously user error, but I can't see what it is.
