Agree with Mr Pooby, as price tag suggest, modo is not aimed to big studio but to freelancer and small studio (but is used in some big production like Rage).
What I like in modo is the idea of doing all in a single package. Its sculpt cannot be compared to zbrush, modo paint 3d can be compared to Mari and rendering is not Arnold, bun in modo, without leave the application, with the some shortcut, paradigms and rules, can sculpt and adding a edge loop at fly where I need, or poly modelling and using some brush for push or add volume to my mesh; some for paint, can paint in 3d, find an error on my uvmap (unwrap in modo is IMO more advanced compared to XSI) correct it and work without issue ect. all without leave the application, whitout import/export errors issue. For me a big step forward in my workflow, now leave a software for doing something in another application remind me the worse Lightwave workflow...
Rendering is really fast and simple, no issue with it, I think they want a system more useful and power possible without issue, very friendly. Preview window is really nice, can paint a texture and control in a fly how its work with my material.
Agree when Mathaeus said XSI workflow is more advaced, fast and efficient in modelling and rigging, but, if we excluding rigging (the most new part in modo), all modo is customizable, like GUI. My idea of gui is softimage, but if I want I can cage modo gui in a softimage like, some for modelling tools, modo can combine tools in pipeline tab, not a power solution like modo ICE modelling, but work fast and efficient, also can simple customize the basic tools (right click on pipeline when a tool is active, and select how the toll must work when you active it). When customize modo tools modelling become very fast. I also like blender 2.5/2.6 gui, cannot understood why people found it so complex
I'll expect a streamline process in 701.
Respect to Luxology, they doing all in house, from modelling tool to rendering engine (if we excluding Ikimena, all the software done by luxology hands)
Hope they will doing better and better, is good have some concurrent software, so AD are not alone
