1. Add the Seamless Backdrop
From the KeyShot menu bar, select Edit, Add Geometry. The first set of choices include Ground Plane, Backdrop Ramp, and Backdrop Round. Backdrop Ramp and Backdrop Round are your choices for a seamless background with soft a transition with no edges of a ground plane showing.
2. Adjust the Backdrop
To move or scale the backdrop, right-click on the backdrop and select Move Part or select the object from the Project, Scene tab, and adjust the location/scale from the Position sub-tab. Use the default ground material, or choose a material that has your desired look. With these tools, KeyShot makes setting up your virtual photo studio a quick and easy process.
