Thanks for any help on my very basic problem. Opening Blender in Sculpt mode for the first time, there was a "Sculptris-like" sphere that I cannot seem to get back to or add. I want to work with this type of default as a starting point. I can add a mesh sphere, subdivide and use sculpt mode, but this isn't the same kind of modelling. When adding a "Metaball", because it isn't a mesh (?), I cannot use sculpt mode. I could completely uninstall/reinstall Blender (maybe),and set it as a default in preferences, but that is a work around that leaves me ignorant of what I need to know. I have my reasons for wanting to do this in Blender and not Sculptris.
I am using a Mac running Mojave. Thanks, Brett
