I am trying to texture a high poly sculpted model, making UV unwrapping impractical. The object is a spiral horn. The texture has rows of color that I want to follow the spiral. Is This possible? I've tried changing to polar coordinates, like in this example How do I make a procedural swirl texture? But I can't seem to get that to work.
It seems to work fine if you unwrap your object with the Follow Active Quads option (select all your faces in Edit mode, then one last face then U), now your unwrap is completely square and your texture will follow along. Then create this nodes chain: Texture Coordinate (UV output) > Mapping (play with the Rotation angle) > Texture > etc.
