These are six fully-3D Cartoon Trees that look like 2D, any angle you look at them from.

Lighting and shadows are directly painted into the color textures, so the trees should be set to ignore any scene light. This is set up exactly like this in the provided Max, and Blender format files. For other provided formats (obj, fbx and 3ds) you will probably want to disable lighting for the tree objects in your software of choice.

The models are all quads, subdivision-ready.

They come with color texture only: 2048 x 2048 png file per tree, comprising both trunk and foliage.
