VR Sketch is a tool for editing and visualizing architectural models from SketchUp in virtual reality. See https://vrsketch.eu/documentation.html for details
The present version does not aim for photo realism and instead focuses on having a cartoonish but well performing mode that lets you edit SketchUp files 100s of megabytes in size.
You can also share your models with others and view them together!
