The environments was the absolute only reason why I purchased Carrara, already owning Lightwave, XSI, ZBrush and others (and Vue 5 Inf).
I found that in Carrara you could really
model as opposed to Vue, (metaball, vertex and
spline!) Carrara also has real 3D views (I can't stand Vue's viewports and how they work.) The complete Poser model import (hair and animations) was the cake icing...
Once again, the only app I consider similar to Carrara is C4D - that and plus MOI objects went in looking
exactly the same as in MOI was the reason why I added C4D to my toolbox.
