not quite got my head around isect yet but
was creating chisel tools by accident with a square and a circle (or 'hole')
- id have problems manufacturing your shape
wheres the Pilou tutorial on super-rapid ai renders - that would be good ;o)
Yep Nano Banana (20 images/ Day), Leonardo (150 images /day), Krea (50 images / day) etc... or other free IA replace all old and not so easy render engines! ;)
And if you overpass the day limite you can always make a snapshot! ;)
Some sufficient for a no pro usage!
Ps and you have so crazy real time render functions!
Of course all that is infinite exploration! :)
