vidually or in groups with textures. Textures can be mathematical or image-based and provide added detail
to surfaces.
Clicking the Add Layer menu enables you to place additional layers. This menu includes categories for
various types of textures, materials, shaders, and grouping options. There is no limit to the number of layers
that can be added. However, when using many layers, it is often best to group items for better organization.

surface.
Environment
The Environment setting gives access to the background of your scene. The environment exists like a sphere
that is infinitely far from the rest of the scene. By default, the environment consists of a gradient that has
values shifting from up (positive Y direction) to down (negative Y). The gradient can be changed from four
