When editing an effect, the editor sets up a test scene to display the effect, that allows you to make sure your effect displays properly, and correctly interacts with environment elements.
'Backdrops' are the nodes that tell the editor what it should populate the test scene with.


You can create an Audio backdrop Audio backdrop to test effects that use the audio sampler, or Model backdrop Model backdrops to test particle collisions with the scene, Text backdrop Text backdrops to "comment" a test or demo scene with multiple effects, Image backdrop image or Video backdrop video backdrops to preview the effect with a moving background, Effect backdrop effect backdrops to preview your effect with other effects (especially useful when using Spatial layer Spatial layers), etc...


IMPORTANT: These are editor-only edition helpers, they will not appear in the final effect.

To add a new editor backdrop, roll down the 'Editor Properties > Backdrop' nodes by clicking on the small triangle on the left of the node name, then unroll the '2D Layers (Background)', '3D Layers (Scene)', '3D Layers (Instance)', or '2D Layers (Foreground)' folders, right click on the folder name, pull down the "New backdrop" submenu, and choose which backdrop you want to add.

You can then configure the backdrop properties by selecting it and changing its properties that are displayed in the node properties panel.
