I had the same problem, anyway try this. For this case you need “copies” no “instances” of your mrProxies: 1) Select all your mrproxy-objects you want to offset. 2) Open the Maxscript Listener and type in: $.AnimOffset = random 0 5
i.e. maxscript performs then a random operation on the animation Offset.. You can also use a fixed value, would look like this: $.AnimOffset = 5

Try this one:

1) select the mrproxies that are to be offset

2)
paste into a new Maxscript:
for i in selection do
(
i.AnimOffset = random 0 6
)

-- the script performs a random offset-value between 0 to 6..
