Build Effect

The Build effect works on Meshes and causes the faces of the Object to appear, one after the other, during time. If the Material of the Mesh is a Halo Material rather than a standard one then the vertices of the Mesh, not the faces, appear one after the other in time.

Faces, or vertices, appear in the order in which they are stored in memory. This order can be altered by selecting the Object and pressing CTRL + F out of edit mode. This causes faces to be re-sorted in function of their quote (Z co-ordinate) in the local reference of the Mesh.

	Note on Reordering
	If you create a plane and add the Build effect to see how it works you won't be happy. First you must subdivide it, so that it is made by many faces, not just one, then, pressing CTRL + F won't do much because the z axis is orthogonal to the plane. You must rotate it in EditMode to have some difference in the quote of the faces, and be able to reorder them.

The Build effect exhibits only two NumBut controls (Figure 2):

Len - Defining how many frames the build will take.

Sfra - Defining the start frame of the building process.
