Enabled – Enables the use of VRayDecal. See the VRayDecal example below.
Preview – When enabled, a preview of the material assigned to the VRayDecal is shown in viewport.
Width – Specifies the width of the VRayDecal gizmo.
Lock – Locks Width and Length if both are greater than 0 and one is 100000 times smaller than the other.
Length – Specifies the length of the VRayDecal gizmo.
Fit aspect ratio to bitmap – Оpens a browser window where a bitmap image can be selected and used to resize the VRayDecal based on that bitmap aspect ratio.
Fit aspect ratio to material – Resizes the VRayDecal to match the aspect ratio of the first eligible texture (bitmap) in the assigned material. Note that procedural textures are ignored.
Mask – Masks the projected material based on a texture.

When a mask is used in a combination with a displacement included into the Material, the Mask must be applied into the dedicated slot in the VRayDecal Parameters instead of using the Opacity map slot in the Material.

Projection depth – Specifies the depth of the volume in which the image is projected.
Projection offset % – Specifies the offset of the VRayDecal gizmo in percentages. This parameter can take values below 0 and above 100.
Bend – Specifies the bend angle for the VRayDecal 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 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. See the Fade Out Angle example below.

Exclude – Specifies a list of objects that are not affected by the VRayDecal.
Order – Specifies a layering order when multiple VRayDecal gizmos 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.
Mask– Masks the projected material based on a texture.

.
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 decal user properties – When enabled, uses the VRayDecal user defined properties.
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 VRayDecal.
Render when hidden – Allows the VRayDecal to be rendered when hidden.
