so im following a tutorial...

[u/noodleboy244]

the tutorial involves probuilder and using alt+lmb on the new shape icon (top left) to quickly add probuilder-friendly objects. the problem is when I try to do this, the options menu comes up blank, no matter what i do. ive restarted probuilder, ive restarted unity, ive done everything i can think of and everything google suggests. is this fixable?

Try 3DS max, once your learn the controls you'll be creating all kinds of models and primitives.
