Image files, also known as bitmaps, have a variety of uses in 3ds Max scenes. You can use bitmaps as textures for materials, as backgrounds to viewports, as environment maps, as Image Input events in Video Post, or as images projected from a light.
An image file can be a single still image, or a sequence of images that form a video sequence or animation. When you assign an animation for use as a bitmap, then the image changes over time when you render the 3ds Max scene.
When you render a scene, you can render a still image or an animation. You can render to most of the formats listed below. Some of the formats support various options. If there are output options, these appear in a dialog that is described along with the image file's format.
