As the topic title says there are 2 things I'm having trouble figuring out how to do with nodes. The first is how to set up nodes to adjust the contrast of a procedural noise. The second thing is shown in a screen shot from eevee. Any help would be appreciated honestly not sure how to make them happen. |

You can use the transform_point, transform_vector and transform_normal nodes: There's no built-in contrast function (yet?), but if you google contrast glsl you can find plenty of examples: You can copy-paste any of those functions into your shader library and they'll be available as nodes. |
