Arrow Per Particle field attributes

Are there any ways to assign field attributes on a per particle basis?

For example, age affecting gravity direction. The older particle is, the bigger is X field direction.

Of course, we can affect position with expressions. But it's not a convinient way if we have more than one field, because with expressions we have position after all fields, not only one, were applied.

Any ideas?

In the Maya help docs, search for: per-particle field attributes

the essential part you will find is:

Create a per-particle attribute of float or vector type on the particleShape with the name fieldName_attributeLongNameOnTheField or fieldName_attributeShortNameOnTheField. The type for the per-particle attribute you use must match the attribute type on the field.

For example, create airField1_magnitude to control the magnitude on airField1.

Cheers, C
