The user interface IS the reason i use bryce. It it what I know and what allows bryce to be friendly to everyone. Let us not forget the mission of kai krause, to "create a powerful program yet enchanced with an interface simple enough that anyone could use it." The mojoworld interface IMO needs some work. THe icons are too small, some are misplaced, and it feels a bit awkward. I despise the vue interface. It confuses me and I can't do anything with it. When trying the demo, I could not find out how to rotate an object within the 10 minutes i spent, hence closing the application in disappointment. SImilar to the 3dsmax interface, in which you have to select a certain cursor to rotate, another to resize, and another to move. It is also very difficult to move things freely in 3d space. Often the motion is confined to one axis at a time! Now the bryce interface I love. It is well organized, customizable, (moveable palettes) and can hide within a number of advanced features while still leaving them accesible. (for example, the material editor is its own space, rather than trying to squeeze it into a window in the UI; pulldown options for all editing tools like rotate, scale, etc.)And that marks a well designed interface. It retains all the advanced options, but does not try to cram all of them into one space. And honesty, who uses all 4 views at once anyways? Maybe from time to time, it could be useful to have an accesible alternate view. Why not simply upgrade the UI to make it more customizable? I.e. make it so the user can configure it like the vue interface if they desire, but at the same time let it also be configurable the the original bryce views and everything in between. All that aside... If bryce's interface were to change significantly in layout without an option to configure it as it currently is, I WOULD NOT CONTINUE TO USE BRYCE, and I am sure there is a large portion of the bryce community that feels the same way.
