Mutable for Unreal Engine 4 | Projector Parameter Node
Updated 132 Days AgoPublic


Function

Expose a runtime modifiable projector parameter from the Customizable Object.


Use Cases

Put a tatoo on a character or a decal on a jacket allowing the player to choose the location and size of it.


Node Properties

Copy (button): Utility for copying the current transform seen in the Preview Instance Viewport. Useful for applying the same transform to different projectors or to manually save a copy of the current transform before trying some new location.
Paste (button): Utility for pasting the output of a projector copy button. It allows to set this projector transform the same as the one copied from.
Projector Bone (dropdown): Utility for setting the gizmo location and rotation to match the chosen bone. Really helpful for cylindrical projectors.
Parameter Name: Name of the projector parameter defined by the node. It has to be unique within all the parameters in this customizable object hierarchy. Used when coding or within blueprints to refer to this parameter.
Projector Type (dropdown): Allows choosing between planar, wrapping and cylindrical projectors.
Planar projectors are best on more or less flat surfaces.
Wrapping projectors are intended to use on top of more complex geometry.
Cylindrical projectors are intended to use as wrap around elongated sections of mesh smaller than the projector radius.
Projecion Angle (degrees): When a cylindrical projector is chosen, defines the angle around which the texture will be stretched. An angle of 360º means that the texture will wrap around and the ends will touch at the back. This parameter is ignored when the projector type is not cylindrical.
Parameter UI Metadata: Metadata associated to this projector parameter.


(red 3D gizmo): Used to define the projector default transformation: location, rotation and scale.

For planar and wrapping projectors: The red box defines the volume that will be affected by default by the projector. This can change at runtime when the parameter is modified.

For cylindrical projectors: The red cylinder defines the volume that will be affected by the projector. It is further limited by the projection angle. Both can change at runtime when the parameter is modified.


Output Pins

Value: Projector that can be relocated, resized and/or rotated at runtime. Default transformation defined by the red gizmo.
