At some stage real time raytracing will be a thing.
This particular example is in Beta but works in Blender and has some permissive licenses. (Hand waving away the closed, commercial part)
I’m not a Blender expert, does anyone know if there is a timeline for including RT raytracing in Blender. A quick Google didn’t seem to mention it (apart from what I linked to above but I don’t think that is official Blender)
Here are its licenses.
