Base models done in just half an hour with Lightwave 3D Modeler (it is based on a real cup of mine
), setting and illumination in Blender 2.9 in three hours, rendered of about 20 minutes in LuxCoreRender for blender with an NVidia GTX1070 8gigs, OIDN denoiser, light tracing on with an oldie AMD FX-8150 
Comments are welcome.
