Yeah, thats what I'm thinking. Does pinning 4 detectors cause a big increase in resources?
Not unless you have a large amount of instances that need the dummies.
The most efficient method would be to make separate objects for the detectors, and put them in a container with the object.
Make as many image points as you need and label them sequentially, d0, d1,d2....
Then on creation make a loop and place them at imagepoint "d"&loopindex.
