This node allows render-time automatic assignment of UV coordinates, projected on each axis. This technique is useful for surfaces that are difficult to unwrap and bake UV coordinates on and works for color, bump and displacement textures.

Shows three textures projected on each axis, with blending

Different texture projected onto each axis and blended


Same Image On Each Axis

When enabled, this option forces Image X shaders to be executed for all axis projections. When disabled, Image Y and Z shaders will be executed for the Y and Z axis projections respectively.

Same Image On Each Axis: Enabled








Image X/Y/Z

The color for the X/Y/Z axis projections, respectively.

Image X/Y/Z Alpha

The alpha for the X/Y/Z axis projections, respectively.

Blend Amount

This value dermines how much of the color results for each axis can overlap and be blended together. Having some amount of blending results in a soft transition between axis colors, instead of a hard edge.

Blend Amount:

Blend Curve

This value determines the power curve of the axis overlap blend and can be used to tighten or slacken the blending effect between axis colors.

Blend Curve: 1.0

Blend Amount: 1.0


The UV projection for each axis is computed from the coordinates of the object that is being shaded. Because objects can vary in size and location in the world, the options below allow you to tune how the object coordinates are mapped onto uvs.


These values scale the projected UVs computed for each axis.

Larger objects will require smaller scale values in order to bring UVs within the 0-1 range.

Scale X, Y, Z: 1.0, 1.0, 1.02.0, 2.0, 2.00.3, 6.0, 4.0


These values offset the projected UVs computed for each axis. Combined with the Scale option, the UVs for each axis are modifed like so:

Axis X:

u = (u + Offset.z) * Scale.z

v = (v + Offset.y) * Scale.y

Axis Y:

u = (u + Offset.x) * Scale.x

v = (v + Offset.z) * Scale.z

Axis Z:

u = (u * Offset.x) * Scale.x

v = (v * Offset.y) * Scale.y

Offset X, Y, Z: 0, 0, 00.5, 0.5, 0.52.5, 2.5, 2.5


These values, in degrees, rotate each axis UV projection respectively, so the Rotation.x value rotates the X Axis projection etc. This rotation is applied after the above Scale and Offset adjustment.

Rotation X, Y, Z: 0, 0, 045, 60, 90

Projection Space Type

This specifies the projection space type, which determines which object shading coordinates are projected into uv coordinates. The options are as follows:

Projection Space Type: WorldObjectReference

Create a Texture Reference Object in Maya to get Reference mode to work.

Add a Redshift Object tag to your object and select a Source Object or create a Snapshot under the Redshift Object > Geometry > Refrence section as seen below.

To use the TriPlanar's Reference projection type in 3ds Max, ensure the object has a Redshift Mesh Properties modifier (tessellation and displacement can be disabled if not required).  By default, the object's reference geometry will be evaluated at frame 0.  This is configurable in the modifier.  The reference geometry can optionally be taken from another object in the scene.  The frame number setting also applies to this object.

The triplanar node reference feature needs not only the rest position but also the rest normals to work. The rest normals attribute must be enabled in the Rest SOP setting the Rest Normals option to “Add Normals”
