If you have a particle system being affected by a field, you can control the magnitude (or any other parameter) of the field on a per-particle basis. Here's how:
Let's say starL_nParticle is being driven by approachCurve_volumeAxisField
- Create a new attribute on star_nParticle
- Make the new attibute per particle (array)
- Name the new attribute approachCurve_volumeAxisField_magnitude
You now have a per-particle attribute to control the magnitude of the field's effect. You can create a per-particle attribute for any of the field's perameters (e.g. alongAxis) but the crucial thing to remember is the naming of the per-particle attribute: it MUST be in the form of
Maya will understand that syntax and make the connection for you.
