Defining a base lighting plane

[dpremoli1]

Hi everyone,

I'm trying to figrue out if there is any way to redefine the ground plane Fusion uses to calculate shadows. Currently, it appears that, despite the component being placed on the XY plane, the shadows are calculated based on the plane of the lowest place component. 

In the case below, I am designing a machine that has a piston that retracts underground, however, the shadow plane moves with it the moment it goes past the base of the machine (aka the "floor").

Fusion 360 always puts the ground plane at the point of the lowest geometry or the lowest origin.

There are two ways to reslove this.

1. You simply model a ground plane. That's what I do most of the time as I can also texture that ground plane to my liking.

2. In the render workspace, to to the scene settings and enable "Ground plane". The "Position" cross-hair allows you to manually position that ground plane. An manipulator arrow will appear in the viewport . It can be dragged with the mouse to the desired location.
