Excellent Rendering but Complex
I suppose all things good tend to be complex - and expensive. Brazil is not difficult to learn to use at the basic level, but since there are so many options, tweaks, etc, getting the results you really want can take time. The most challenging are the material editors. Producing materials can be confusing, and none come loaded with the software. I think that is one of my only gripes.
It can produce some amazing images, however, that just blow away the competition, particularly Flamingo, which just doesn't have the quality results. I really appreciate the lighting effects and ability to set subtle image values in many different and unique ways.
