Define gravity in DOPs using SOPS

[tomwyn]

Hi all,

 

Is there a way to 'activate' gravity with bouding object in DOPs?

 

I've defined a group in SOPs using an anitated expanding sphere, used a group combine do define active/inactive groups, and my aim is that anything inside the sphere is effected by gravity whereas anything outside isn't.

 

However I'm not sure how I'd bring it into DOPs, and if gravity can even be controlled in this way without using VEX code.

 

I'm trying to control the falling of a fluid object from top to bottom.

 

Any ideas are, as always, very much appreciated!

 one way to do this would be to fill your sphere with points,  add a vector to each point (call it v).. then use a field force dop and plug  a sopgeo dop into the second input which points to your points.  Just be sure to enter the name of the attribute (in this case "v") on the field force dop.  There are some good examples in the help.
