The Hydra Viewport shows a 3D render of the USD stage. USDView can be configured to load with different Hydra renderers. The
viewport and renderer settings can be edited from the View Menu.
Within the viewport, you can use the following methods to navigate the three-dimensional space:
The focus control zooms the viewport camera in on a specific prim. When you focus on an prim, you can orbit that prim.
To focus, click a prim and press the F key.
The orbit control rotates the viewport camera around a given point.
To orbit, first use focus to select an prim. Then, hold the Alt key and the left mouse button, and move the mouse.
The pan control moves the viewport camera parallel to the viewpoint.
To pan, hold the Alt key and the middle mouse button, and move the mouse.
The dolly control moves the camera forward and backward in the space. There are two ways to dolly:
Scroll on your mouse wheel.
Hold the Alt key and right mouse button, and move the mouse.
