appleseed scene files

Because mayaseed creates appleseed scene files it's useful to know a little bit about them. appleseed scene files are simple plain text XML documents with a .appleseed file extension that contain information about your render settings, objects transforms, links to external textures and geometry and a whole bunch more.

Some of the more important entities defined in the appleseed scene file are as follows:

<project>

The project element contains all information on the appleseed project, surprisingly.

<scene>

The scene element contains all information about the 3D scene itself, lights, cameras, textures, geometry etc.

Inside the scene element you have, amongst other things, <assembly> and <assembly_instance> elements. Assemblies let you group and instantiate scene elements and can be thought of as a kind of group.

<output>

The output element contains info on the output format of your render, such as color space, resolution etc.

<configurations>

The configurations element contains the main parameters that affect how the renderer performs: sample count, lighting engine etc.
