Several custom tags are provided for determining how objects are exported and rendered:
 | A Camera Tag may be attached either to a C4D camera object, or to a Maxwell Scene object. While the physical attributes of the camera, when written into the MXS, are taken from the physical characteristics it has in C4D, the Camera Tag is used to control the Maxwell-specific aspects of cameras which have no correlation in C4D. In all cases, the resolution of the export is taken either from C4D's Render Settings, or from the size of the active viewport, depending on which command is used to start the export. | |
 | Add an Object Properties tag to an object in C4D to obtain control over the various Maxwell 'Hide from X' mesh attributes, as well as many other export- and render-time factors. | |
 | A Render Region tag may be added to either a C4D camera object, or to a Maxwell Scene object. If one is found during export, it will be used to constrain the render engine to process only the specified portion of the image. | |
 | A Hair tag is added to a Cinema Hair object in order to determine how Maxwell Hair will be generated. | |
 | A Grass tag may be added to any object which produces a mesh. A single tag may be applied to an entire hierarchy, affecting all mesh-producing objects in that hierarchy. | |
 | A Particles tag determines how particles will be exported from Cinema Particle Emitter and Particle Geometry objects. | |
 | Attached to a Null, an RF Particles object, or to Particles Emitter or Geometry, this tag controls a procedurally-generated volumetric region at render time. |
