A series of sketchup tutorial on rendering with Twilight by Brian Bradley
Brian Bradley, the recognized author of Photographic Rendering with V-Ray for Sketchup, comes up with a series of useful sketchup tutorials on how to render with Twilight, an exclusive low cost third-party renderer for sketchup. These sketchup video tutorial series will help you to produce extremely pragmatic 3d architectural drawings (involving interior/exterior elements) with the lights, materials, camera, and render options in Twilight.
One can also learn the significance of reflectance in materials, as well as how to control and save rendering presets, how to make perspective perfect, tone, and exposure in the camera, and how to generate diversified types of materials. The final chapter highlights rendering your complete arch-viz scene for a couple types of output, along with animation and composites.
