assuming no clothing involved... problems: * bump files often in the wrong node, and also incorrect strength. * transparency often has incorrect settings. dislikes: * materials often look flat and unreal compared to p5/p6 optimized materials, which i'm often using on other objects in the scene. * high polygon count items needlessly bogging down the scene when a lower poly version with smoothing would look the same. * having to make displacement maps for appropriate items such as tiles, embossing, seams, etc. (just want large elements like tiles, not the texture on them, so bump is not the same). * light systems that load an inordinate numbers of lights to acheive what a single IBL or point light can do (if you include lights in your products). * rsr's cluttering up my directories. sorry, it's a pet peeve - i like to have just the pngs. with as many freebies and products i have, doubling the amount of size all the previews take is just needless weight. * figures with parts that would work better if dynamic that are difficult to refactor. if the draping part is in multiple groups for posing, i presently don't know how to join the groups into a single dynamic group. also, it can be difficult to set any of the other types of groups (constrained, choreographed, soft and hard decorated groups). if i understood the grouping tool or uvmapper better, i could probably get around that.
