Join Aaron F. Ross for an in-depth discussion in this video Softening a field with attenuation, part of Maya Dynamics: Creating Simulations (2012).
Another really important attribute for fields is Attenuation.…Attenuation is the fall off, and with a value of 1, which is the default, the…intensity of the field diminishes linearly from the field location to the Max Distance.…In other words, it's going to be at full strength at the location of that field…and it's going to fall off in intensity until it reaches the Max Distance where…the value will be 0.…
If the Attenuation is set to 0 that means it's turned off and instead of a…soft fuzzy boundary around the field, you're going to have a hard-shell around…that field and any object that gets 200 units away from that field this is…going to bounce right off.…Rewind and to play that back, so you see it bounce right back towards me,…whereas with Attenuation of 1, it was allowed to pass through. It deviated the…path because there's a soft boundary around that field there.…
You'll need to work with all of these attributes to get a good result.…You'll need to set the appropriate Magnitude, Max Distance and Attenuation for each field.…
