If Jim Burton's research holds, #1 will fold #1 & #2, # 2 will fold #3, #3 folds #4, etc. If the morphs and rotation channels in question, have their names changes to end with _0 (including the figure in the ERC script) and a Find _0 Replace with _1 (_2) (_3) etc and each saved to the library, then no cross-talk. But yes, Duane, you are right, there will be cross-talk, unless some provision is made. Does the null figure work for props?
