I think that it is quite powerfull, but again I see a big fail on the Graphisoft side that no guide was provided, and the implementation is poor. Few tutorials would help a lot to set up workflows. I find the AC almost good for interiors (very bad handling of non gdl objects such as 3ds models of furniture etc - one hi-poly lamp can freeze the AC 3D engine with ease), but for exteriors it is just substandard. No camera tools (even 2 point perspective is not possible - the real one like the shift in photography), no 3D foliage, slow grass etc. Somehow almost every new tool in AC nowdays is halfbaked when introduced so probably in the future it will get better. I can show few other renders with a little different settings, I am happy with them, but I would love to use more external non gdl models.
