Short description of error
Nothing happens if you plug a wave texture with texture coordinates coming from the tangent node into the bump node even if you put absurdly high strength/distance values.
Exact steps for others to reproduce the error
- Delete cube.
2)Add monkey and put a material on monkey.
3)In the shader editor add a tangent node.
4)Plug output from tangent node into a wave texture node's 'Vector' input.
5)Plug output from wave texture node into bump node's 'Height' input.
6)Plug bump node's output into principled BSDF 'Normal' input.
7)Watch as nothing happens.
Weird thing is if you substitute the tangent node with 'Tangent' output of the 'Geometry' node everything works as expected. But unfortunately you can't get UV tangents from said 'Geometry' node as far as i am aware only the 'Tangent' node can do that.
