Vectrosity Line Tapering

It seems that vectrosity 3d lines automatically taper the further they are away from the initial generating origin. This isn’t optimal for a roaming camera that can go to the opposite end (where the lines appear extremely tapered).

Is there a way to change the tapering at runtime at a point?

Is there a way to disable auto tapering?

There is no tapering, auto or otherwise. Please read the docs about how 3D lines are handled. Once drawn, they have to be re-drawn when the camera moves. You can use DrawLine3DAuto for that.
