(How) can I add a background picture in my render?

Although various configurations can be setup via Material Room menus, and can be managed through the Simple interface, this topic is considered Intermediate level.


First I set a Background Picture, either via the menu File > Import > Background Picture:

or via the Material Room directly, connecting the BG Picture node with the background node:

The BG Picture node is completely compatible to the regular image_map node.

Then I switch ON the use of the picture in the render, via Render Settings:

That is: do use Background Picture or Current BG shader. See the overview on background nodes in general.

When I’m still having problems with the Background, I just check:

  • Whether the GROUND object (or any other object) is obstructing the view
  • Whether I’m trying to load an 16-bit-per-color image (don’t)
