Dynamics chain links

John Larsen's tutorial cover basic usage of old buldin Dynamics utility into Max R2. Because it's not designed to work with xref'd proxy and from other hand it works more faster with low res objects, it's a good idea to make a dynamic simulations using low res objects and then replace them this hi-polygons count version. The easy way that I know is by simple script:

instanceReplace $old $new

(there "old" is your low-res object and "new" is your hi-res object)
