The Decal tool provides an easy way to project one material on top of another regardless of the target UV set. The projected material conforms to the form of the object.

Multiple Decals can be stacked on top of each other, and their overlapping is controlled by the parameters of each Decal object or by their position in the scene.

The Decal parameters are grouped into Basic settings, Variation, and Distribution and Stats tabs.

Width – Specifies the width of the decal.

Length – Specifies the length of the decal.

Fit to material – Resizes the decal to match the aspect ratio of the first eligible texture (bitmap) in the assigned material. Note that procedural textures are ignored.

Fit to mask – Masks the projected material based on a texture (bitmap). Note that the Mask parameter must be enabled and a must loaded through the Load mask tex.

Mask – Enables the use of a bitmap for resizing the decal. The decal is resized based on that bitmap aspect ratio.

Load mask tex – Оpens a browser window where a bitmap image can be selected and used to resize the decal based on that bitmap aspect ratio. 

Invert – 

Use alpha – 

Projection depth – Specifies the depth of the volume in which the image is projected.

Projection offset % – Specifies the offset of the decal in percentages. This parameter can take values below 0 and above 100.

Bend – Specifies the bend angle for the decal in degrees when placed on a curved surface.

Normal angle – Specifies the angle to which the decal is applied onto the surface below.

Fade out – Enables the use of a fade out angle.

Fade out angle – Specifies the angle which creates a fadeout gradient starting from the Normal angle. Values closer to the Normal angle produce a sharper gradient. The maximum fade out angle is 180 and it can't take values less than the Normal angle. 

Include – Specifies a list of objects that are affected by the decal.

Exclude – Specifies a list of objects that are not affected by the decal.

Order – Specifies a layering order when multiple decals are present. The decal with the larger Order value is set on top of the other ones. In case of equal Order values, the bounding boxes of the decals are taken into account for positioning.

Back side – Enables the visibility of the projected image on the back side of the face. This option is useful for objects without an actual thickness where the back side of the polygons is exposed to the viewer.

Use only decal bump – When enabled, the original surface bump isn't taken into account.

Surface bump % – Specifies the percentage of the surface bump that affects the decal.
