I want a 3d modelling program to sculpt things, take high quality renders, mostly focusing on landscapes, planets and space and maybe simple figure posing.
Does anything like this exist online (AI Chat is useless)
you must be mistaken, those results about blender aren't ads for a new blender those are actually suggestions for a 3d modelling software named blender. its very beginner friendly and should have what you need, just learn to read.
