What it is
A variant is one option a placement can pick from: a template, turned by a quarter turn or not, with a weight.

Good to know
Weights are relative
A variant with weight 2 is picked twice as often as one with weight 1. The weight is not a chance of placing at all.
Free rotation
Variants only turn in quarter turns. For any angle, use a Placement Frame with a density formation.
