I am of the target market that has only used Hammer, and although I know hammer quite well i wouldn't say im stubborn in exploring other software. Rather, and i think it was mentioned before, it is more so the time and effort required to "aquire" 3ds max and the plugin, and then learn it (Laziness). Of-course i also think there are limitations when it does have a rather "Pay to play" business model, opposed to Hammer which is provided free with a rather easy to use interface and larger community.
Saying this, do you find a common limitation when reaching out to people with 3ds Max? Is the cost, effort and alternate software all hurdles that have come up time and time again? I am just curious why you would go for an option that is harder to put into the hands of your average user. I really like that you've developed from the ground up, and I can see you are extremely passionate about 3dsMax and WW, but for me personally, I think the time and effort spent would not merit the outcome.
On Topic: I look forward to seeing the entrants submissions in this competition and seeing what WW is capable of. Maybe I'll be put in my place and end up 'acquiring' a copy of 3ds.
