pyrocluster puff as asteroid dust cloud

Posted by Tom Schmidt on April 17, 2017 at 8:15 pm

Hello.

I am trying to wrap an asteroid in a soft, subtle dust cloud.

I’m thinking I’d use a Pyrocluster puff attached to a single particle.

I’m using the standard particle emitter, set to a single particle that has a very long lifetime.

I have no age effects on it, so the puff theoretically shouldn’t change.

I’m using a Pyrocluster puff, so that the asteroid casts a shadow on it. (otherwise I’d use a light with visible light)

The problem:

The particle/puff doesn’t move with the asteroid.

How can I attach it to the slowly turning asteroid?

One note: I do not know Espresso, so if there’s a solution that doesn’t require nodes, that would make life much easier.

If though, nodes are the only answer, please talk to me like I’m a 6 year-old. ????

Thanks in advance!

Tom

The easiest way to do it would be to use a MoGraph matrix object to generate the particle. Then just make the matrix object a child of your asteroid.

So, set the matrix object to Generate>Thinking Particles and set the Count to 1. Done.

Hi Adam.

Thanks for the help, and it seems like it should work.

I’m doing something wrong, I’m sure. I dropped the pyrocluster material on the MoGraph matrix, but there’s no joy in Mudville.

I seem to be puff-less.

Suggestions?

You still have to set it up as if you were using Xpresso/TP, so you need a TP Particle Geometry object and the pyro material goes on that. Of course you also need the Environment Object with the Pyro volume tracer material.

Thanks Adam.

That seems to work for position, but not the rotation. The cloud moves with the position of the null I’m using for this test, but not for the rotation. Maybe I lack a click?

Here’s the project if you want to reference it.

Thanks!

Yep, you lack a click. ????

Go to the pyro material’s shape tab and check the “Use Particle TM” box.

From the help file:

Use Particle TM

If you enable this option, PyroCluster will use the particle’s transformation matrix to calculate the rotation of any puff or atmospheric effect.
