Decals are used to add detail to geometry. Scorch marks, blood splatters and such can be added with this tool, only thing needed is a proper material and a surface to apply it to.
General Parameters:
Name: Name of the decal.
Position: 3D Vector storing the world position of the decal center.
Rotation: 3D Vector storing the rotation for the decal volume.
Scale: 3D Vector storing the size of the decal volume.
Specific Parameters:
Affected surface types: These three buttons will set which types of geometry objects are to be affected by the decal.
Material: Material file for the decal.
Current SubDiv: index of the subdivision currently in use. These are numbered in a left to right, up to down order.
Decal Offset: distance that will separate the decal from the “host” surface.
Max triangles: maximum number of triangles the decal will use when generating the mesh.
