Yes I use brighter3D with quick amazing results. You don't really need documentation as it is so simple to use. Just watch a few youtube videos and you are away. I love the parallel rendering the most as I render kitchens and product for brochures with very photo realistic results. If you want a particular video just ask the makers and they will make one or guide you to a video. The developer even took the time to add features that I requested and I hear that there is a major update coming with even better features and results coming toward the end of the year. Just wish sketchup 2019 would hurry up and release its new version.
