ADD the reference Imagery to the Scene
After selecting the images you imported, they should appear in the VR scene. Pull back on the Support hand thumbstick to exit the reference panel. To move an image, click on one and it will display a green outline to show it is selected. Pressing the green button on your Tool hand will bring up options for the reference image. Now hit the green gear button and select 'Move with sculpt'. Move the reference image to a position that works for you and enables you to model in front of it, and repeat this for each of the reference images. You can also delete images from the scene using this options panel. If you don't select 'Move with sculpt' the image will lock to a position in the scene. This can be useful for adding signs and graphics to your VR scene.
