Oshyan, I know I've said quite a lot about TG2 already, and while often it's the problems that become the most vocal, let me also state that I absolutely love this product as it is already. And has a registered user (Deep), I already believe I have very good value for money even with the Tech Preview.
This is a wonderful program, and I any other hobby or spare time I had previously to the release of TG2 has all but evaporated as of late, simply because I have so much fun with it. My wife who is a matte painter has also expressed her admiration for the software, noting that it is a great resource for her to quickly generate photoreal elements easily.
