You can add high-quality rendering to the free SketchUp software even if you don’t have any of the full-featured commercial rendering programs like 3ds max, VRay, maxwell etc. But don’t let that stop you… Kitchen rendering One feature that is missing in SketchUp, though, is photo-realistic rendering. Most of its modeling feature set is even available in the free version and with downloadable Extensions, anything is possible. Quickly creating 3D-models and doing sketchy renderings is clearly the strength of SketchUp.
