Well, I agree in part with Silver, Bruno, and Alex.

1. Esprit with the initiation of Vue6 can populate already created Ecos and it can edit them VIA Height, slope, and material restraints, but not create them..
2. Pro Studio can edit many parts and even create some fantastic foliage and Ecos, but can not as shown above DEEP EDIT Objects and many other Finer tuning.
3. X-Stream goes above and beyond where Infinite has been left off and in a PERFECT SCENARIO would be able to trump all other versions of Vue, but it can not do it's Bug issues.
   Interesting thing to think about is that ILM has No Public Reported Problems with X-Stream.
   Could this be part of: "It's Not Who You Know, But Who You " ??????
   In any case I have had very few crashes with V6 Pro Studio and have learned to FEEL when one is about to happen and I able to make adjustments in most cases to insure that a crash does not happen. That is the Key to success in part, "Not The Next Version of Vue", which should only Enrich your Expertise with the Software.

I would rather be Politically Incorrect,
Then have Politically Correct-Incorrectness!!!
