This isn't a tip or trick, but I had to post on this one. I know that I always talk about modeling in SketchUp and rendering in Max. Well Jacques from Cape Town, South Africa has proved that SketchUp can compete as a high-end 3D modeling contender. His stunning care for detail has been shown in his latest model of the HMCS Snowberry. The slideshow is also a good documentation of just how he managed to model organics in an XYZ world.
The images were modeled in SketchUp and rendered with Vray.
He has also been gracious enough to provide his models here for SU enthusiasts.
