2D Mapping Coordinates

Like any 2D map in 3ds max, mapping coordinates control how a combustion map is positioned on objects.

For geometric primitives, mapping coordinates are usually provided automatically. For some kinds of geometry, such as meshes, patches, and NURBS surfaces, you must apply a UVW Map modifier to provide mapping coordinates. See Tips for Working with a combustion Map in 3ds max.

Controls in a 2D map's Coordinates rollout affect how the map is positioned.

These controls are described in detail in the 3ds max User Reference and the 3ds max online reference. When you work with a combustion map, note the following points:

• When you apply a combustion map to an object, leave mapping set to the default values of Texture and Explicit Map Channel.
• When you use a combustion map as an environment map, set mapping to Environ and then select the mapping shape from the Mapping list.
• The offset, tiling, mirror, and angle controls are useful especially when the size of the projected combustion map is smaller than the geometry.
• You can choose between UV, VW, and WU projections. (You can also do this from the combustion Parameters rollout, as described in the following section.) UV projects onto the surface of geometry like a slide projector. VW and WU project the map at right angles to the geometry. With a combustion map, UV is almost always the most useful choice.
