This nodes blends colour input using the triplanar method. Essentially, depending on the direction of the normal, either the X, Y or Z inputs are being used respectively. The colours provided by the inputs are blended the further away the normal points from any of the main axes.

These are the standard compositing controls as provided by the native 2D mapping nodes as well.

This controls how hard/soft the blend of the planar projections is as the normals point away from the major axes.

0% Blend	20% Blend	50% Blend	100% Blend

We recommend a value between 5% and 20% for most uses.

This controls if the blending is computed in local or in world space. Please note, this only affects how the blending is computed, not how the images are projected.
