ThreeJS Understanding Where Lights Are

I've been trying for around 30 minutes to position a pointlight at the bottom of my model with very poor results. I don't know how many units my model is and I can't seem to exactl

Solution 1:

Each geometry has a boundingSphere attribute that you can use to figure out the size of your object. https://threejs.org/docs/api/core/Geometry.html If the attribute does not have a value you can compute it using geometry.computeBoundingSphere();

As for the lights for each of the light types there is a helper function associated with it that will show you where the light is:
