// BrushBuilder: Base class of UnrealEd brush builders.

|
//
|
|
// Tips for writing brush builders:
|
|
//
|
|
// * Always validate the user-specified and call BadParameters function
|
|
// if anything is wrong, instead of actually building geometry.
|
|
// If you build an invalid brush due to bad user parameters, you'll
|
|
// cause an extraordinary amount of pain for the poor user.
|
|
//
|
|
// * When generating polygons with more than 3 vertices, BE SURE all the
|
|
// polygon's vertices are coplanar! Out-of-plane polygons will cause
|
|
// geometry to be corrupted.
