Overview


The TriPlanar texture allows quick assignment of bitmap and other 2D textures on objects that don't have suitable UV coordinates. The texture works by projecting one or more textures along the object-space axes depending on the surface normals of the shaded object.

The texture works both for colors and bump maps.

 

 

 

 

Parameters


 



Texture Mode – Specifies whether to use one or three textures for the different projection axes. For more information, please see the Texture mode example below.

Same texture on all axes – Projects the same texture along each local axis.
Different texture on each axis – Uses a different texture along each axis.

Texture X – The texture to project along the X axis when the Texture Mode is set to Different texture on each axis.

Texture Y – The texture to project along the Y axis when the Texture Mode is set to Different texture on each axis.

Texture Z – The texture to project along the Z axis when the Texture Mode is set to Different texture on each axis.

Scale – Adjusts the size of the texture. For more information, please see the Scale example below.

Blend – Controls the blend between the different projections. Lower values produce sharper transitions between projections. For more information, please see the Blend example below.

Frame Offset – Moves the point relative to which the textures are projected.

Texture Rotation – Specifies rotation (in degrees) for the projected textures around the respective projection axis. If Random texture rotation is enabled, non-zero components of this parameter specify increments for the rotation. For more information, please see the Texture Rotation example below.

Random texture offset – Randomizes the texture offset based on the Random Mode.

Random texture rotation – Randomizes the texture rotation based on the Random Mode. The rotation can be locked to specific increments (i.e. 45 degrees only, or 90 degrees only) by setting the Texture Rotation components to the desired increments for the different axes.

Random axis – Randomly permutes the projection axes based on the Random Mode.

Random frame rotation – Randomly rotates the entire projection space based on the Random Mode.

Random mode Specifies how to generate the random seed needed for the various randomizations: For more information, please see the Randomizations example below.

By face ID – Computes the seed based on the face material ID of the mesh.
By render ID
– Computes the seed based on the render ID of the objects.

 



Example: Texture mode



 

Texture Mode is Same texture on all axes

Texture Mode is Different texture on each axis
and different textures were specified for the X, Y, Z axes

 

 



Example: Scale



 

Scale is 0.005

 

 

Scale is 0.01

 

Scale is 0.02

 

 

 



Example: Blend



 

Blend is 0.0

 

Blend is 0.1

 

Blend is 0.3

 

 

 



Example: Texture Rotation



Texture Rotation is 0, 0, 0

 

Texture Rotation is 30, 0, 0

 

Texture Rotation is 0, 30, 0

 

Texture Rotation is 0, 0, 30

Multipliers



 

 

Texture X – Specifies a multiplier for the texture loaded in the Texture X slot.

Texture Y – Specifies a multiplier for the texture loaded in the Texture Y slot.

Texture Z – Specifies a multiplier for the texture loaded in the Texture Z slot.

 

Notes


  • Currently TriPlanar only supports bitmaps when rendering with V-Ray RT GPU.
