Sketch rendering is a method for previewing concept sketches directly on basic geometry. This technique is ideal for quickly drawing in details rather than investing modeling time on undecided design features and details.
Canvas
Project Sketch converts images into a special shader and layers it onto the model. The original shaders applied on the model remain, leaving them completely adjustable.
You must have images in Canvas planes in order to use Project Sketch. You can create Canvases using Alias integrated sketching, or import images using FileImportCanvas Image.
