It has been very helpful to me (as it should be), but they could make some enhancements in their interface, like an option that allows you not only change color of your model's surface texture as well changing its roughness without having any visible difference between them; also there are things I dislike about this program such us how complexed everything seems sometimes even when using advanced functions because we do need patience with our computer if want achieve great results! Maybe something will improve over time? But so far no complaints here!! We're solving problems related specifically by design requirements analysis processes through 2D/3d modelling application called METASEQUOIA which makes visualization easy task due complexity nature these projects present themselves.
