permanently add to group, Flip

[Cain&Able]

Hey guys, 

 

I'm using an attribute transfer to test whether my object is close to my flip sim points and then adding that to a group.

When it is I apply different fields to that group. Problem at the moment is when the object moves away its no longer in distance so reverts to original group. 

 

Anyway to permanently add points to a group after they come within a certain distance?

 

Using the Sop Solver node.

 

Thanks!

Save it in a attribute and take the min/max with prev timestep.

 

Ex.

Measure the distance to the object.

Do a minimum compare with prev timestep.

Group based on the result.

or only run your proximity test on particles not already in the group.

Cool thanks! Problem solved.

 could you also change the merge operation on the group sop to "union with existing" instead of the default "replace existing" ?

Cool thanks! Problem solved.

Used a vop sop in the end. Create an empty attribute , use a point cloud to get the distance then add it to the empty attribute if it meets the condition.

Hey Ludwig, can you upload a hip file to share how you solved it, or any other friend can do a hip file?
