Page History

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.

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.

Projection depth – Specifies the height 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.

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. See the Fade Out Angle example below.

Fade out angle – Specifies the angle where the decal effect fades out, e.g. if set to 45, the minimum fade out angle value is 45 and the 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 value is up to 180 . By default the Fade out angle value equals the Normal angle value and and it can't be set to be lower take values less than the Normal angle value. See the Fade Out Angle example below.

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. The material

Back side – Enables projection on back face. Note that if the result from the VRayDecal is not immediately visible, further adjusting of the Normal angle parameter is neededthe 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 displacement – When enabled, the original surface displacement is not taken into account. See the Use Only Decal Displacement example and the Decal Displacement example below.

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.

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

Show bend center – Enables a visual representation of the bend center in the viewport.

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