How to set the background for a runway show

Question: How to set the background for a runway show

Solution:

Scenario 1: To change the entire background, right-click on an empty space in the 3D window ▶ Scene Environment. You can upload a background image and adjust the fill mode. (When exporting, make sure to check the option to use the 3D window effects.)

Scenario 2: To insert a background image into a prop, go to File ▶Import ▶Sketch. Then, manually adjust the size and position. (When exporting, make sure to check the option to use the 3D window effects.)

Scenario 3: To add an animated background, render a sequence of transparent background images locally, then import them into external software to composite the video and add the animated background (e.g., in Premiere Pro or similar software).
