Cropper

The newly re-written Cropper plugin for MODO is the missing 'Crop' tool for your renders. With Cropper you can zoom in on a small part of a high res render, fire off pixel-for-pixel test renders at the final resolution, and even save those crop regions so you can get back to them on demand. A must-have for pretty much anyone who renders complex scenes in MODO. mechanicalcolor.com/cropper
