I would like to use a panoramic backdrop for my 3D views. How can I set my backdrop so that it is spherical?


The backdrops available in the Chief Architect Library Browser are rectangular images that will wrap around the 3D model in camera views - as though they were applied to an imaginary cylinder.

A spherical backdrop, on the other hand, is a specially edited image that will look distorted when applied to an imaginary cylinder but will look correct when instead applied to an imaginary sphere around the 3D model.

If you have a spherical backdrop image that you would like to use in the program, you can import it into the Chief Architect Backdrops library and then specify it as Spherical.

To import a spherical backdrop

  1. Select File> Import> Import Backdrop from the menu to open the Import Backdrop File dialog. Browse to the image file that you want to import, select it, and click Open.

    The image we are using in this example is fieldsmall from openfootage.net. It can be downloaded from the attachments section of this article.

  2. In the Backdrop Specification dialog check the Spherical Backdrop checkbox and click OK.

  3. To apply the backdrop, select 3D> 3D View Defaults from the menu.

    • In Chief Architect X4 and prior, this was called 3D Settings.

  4. Under the Backdrop panel, click Select Backdrop and browse to your backdrop in the User Catalog.

  5. Create a camera view to preview the backdrop.
