Auto Coordinates

In general, if a texture node is not being controlled by UVs then it should be controlled by a Texture Coordinate node set to Object. Otherwise, it will look distorted in areas. Power Node’s Auto Coordinates feature automatically generates a Texture Coordinate node (set to Object by default) if not present in the material and places it to the left of all the other nodes. Then it will automatically link the Texture Coordinate node too any node you create that has a Vector input.

Upon the addition of any node with a Vector input, a Texture Coordinate node is added. A Reroute node is also added to make it easier to simultaneously change the Texture Coordinate setting for all nodes added to it in the future. This allows you to use Power Node’s Link Swap feature by holding Alt and left-clicking anywhere on the right side of the Texture Coordinate node to quickly change its settings for all connected nodes. Note that here the Texture Coordinate node is open, but by default it is closed shut when newly generated (as in the image below).

From here, any new node you create with a Vector input will be automatically connected to the Texture Coordinate node after it is placed. Here we just added a Voronoi Texture which was immediately linked to from the Texture Coordinate node after placed thanks to the Auto Coordinates feature.

Newly generated Texture Coordinate nodes are set to “Object” by default but you can change the default setting to UV or any other Texture Coordinate setting.
