I do lurk here still-- mainly because I really like Michael and his program, though I seldom use it these days.

Here are a few quick renders of your "dymaxion" vehicle done in Blender. Note none of these 1920 x 1080 renders took longer than 3 seconds EEVEE (that includes volumetric effects, area lights with soft shadows, HDRI maps and DOF!)

Took about an hour to set it up-- much of it adding decals and modifiers to surfaces.
