LuxCoreRender - Powerful open-source 3D tool, a bit complex
Over the past almost two decades, I've done a great deal of 3D design. After some trial and error, I ended up using SketchUp for actual drawing and Kerkythea for rendering. Both of these programs are primarily intended for Windows, not Linux. That said, I got both of them running really well in Linux - part of my migration away from the proprietary operating system. So far so good. But we can perhaps do better?
The one obvious limitation of Kerkythea is that it only does CPU-based rendering. No GPU. Effectively, this means if you have a beefy graphics card, it just sits idle there. But in practice, it could be used to render your models a good order of magnitude faster, perhaps even more, than using your o'dinary processor. This intrigue sent me on a search for a new, modern and Linux-native rendering tool - with the necessary SketchUp export plugin, of course. I found LuxCoreRender, and this is my early review and impression of that experiment.
