I've been using it the past few days, and starting to like it more and more, and better than arbaro.
First off, its FREE, and the results are actually quite detailled for a free object maker.
I am mostly using it for medium to distant foliage. It would work for up-close foliage too, but would require serious shader work.
Yes, it is slow, but thats fine with me, if its free and not unusably slow.
It DOES require import into Poseray vs direct import into TG2. If you don't, the shaders are super dark, regardless of what you do. Poseray normalizes something in the obj file materials that make it work better with the current version of TG2.
It DOES require shader tweaking in TG2 once imported. In fact, I always go back and retweak shaders in all objects I've imported into TG2, even pre-made or pro-made ones. They always look better if this is done.
