Only convex shape can be trigger volumes.
you can not make a compound collision a trigger volume, but you can make some of the pieces of of a compound collision a trigger volumne.
Is that what you are trying to make?

Not I did not decided against that, Maybe I forget, My impresion was that this was working. However there is somithing you should know.
when you make a compoumd collision, the shape are fixed, so if the body is dynamics and moves or rotates, the triggers will move with it.
So this is the kind of feature that sound good on paper but that it is not that practical.
Of course Trigger volumes in compound shape can be used for defining irregular triggers regions, is that how you are trying to use them?
also on this

Removing contact is teh old way to simulate trigget volome,
I usually do not implement functionality in Newton that can be implemented from the client app. There is a reason for using trigger volumen.
First of all they do not calculate contacts at all, so you to not get contact slot from the Max contact count that is allow for colling pairs.
Secund they are much faster than letting the contact be calculated just to be rejected in the callback.
