Click or click-drag in a modeling window to place the pivot point of the new Texture Projection Object.
A new shader appears in the Multi-lister, having a Projection texture mapped to its Color.
Tips
The projection objects are moved by their pivot points. When they are created, the Planar and Tri-planar projections are not centered on their pivot points.
When you are using the Camera projection, it may be helpful to pick the objects you want to texture first, then use the Look at tool in the Cameras palette before creating the projection object.
