i would be nice to have Ldraw import support that would enables us to import Lego models created in bricklink studio or other lego cad software. also possibility to animate characters and objects would be amazing. this would also include Lego materials where you can choose how much scratch each lego part should have. this would also enables people to be creative and make amazing lego models of their houses or projects 
as of right now there are two ways we make lego renders. 1 is with bricklink stuidio witch can be limited but makes good result and the second is to use blender or 3ds max wich requiers a lot of knoweledge witch can be to hard for some to learn. it would be amazing to have it in 1 software.
