Triplanar Mapping
Triplanar mapping is a Material Operator that is a useful tool for when needing to map textures on a material which is being applied to an asset that doesn’t require the use of UVs. Under the Material Property you must select ‘Add Operator’ in order to activate this operator. Once added you will be able to apply the operator to various sections of a material, such as the Base Image or Normal Image. It works by projecting the same texture on the X,Y,Z axis simultaneously and allows the user to control various elements such as the amount of blending between the 3 Axes as well as scale and rotation. These projections work in either World Space or Local.
Projection
Allows user to select the type of projection space:
World
The coordinate system for the entire scene. This mode is useful when several objects need to be mapped with the same triplanar texture and to show consistent mapping.
Local
The projection is done in local object space. When the object is moved/rotated/scaled, the texture moves with it.
Blending
Control the blending of the projected textures on the X,Y,Z axis using a slider. Slider range is from 0.01 - 1.00. A value of 1 denoting 100% blending of the textures and 0.01 denoting 0%. The Triplanar operator default blending value is 0.5.
Translation
Allows the user to position the texture on the X,Y,Z axis. Values for translating the texture depend on whether using Local or World space.
Rotation
Allows the user to rotate the texture on the X,Y,Z axis.
Scale
Scale values will depend on whether using Local or World space. A scale of 1.0 XYZ in World Space would be a scale of 100XYZ in Local.
