You can use a trick:
If the strength of two blobs does not interact (i.e. they are far enough
away from each other) you can remove one of the blobs without changing the
result. You can use this fact to do some tricks with CSG: Construct a
complete body with blobs, then copy each arm and leg blobs. Use for example
a plane to clip away the interacting parts of the main body and do it the
other way around for each arm and leg. It is a lot of testing usually, but
it works (not perfect, but better than having them interact).
