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.
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.
