The Profile is an utility node that outputs a simple greyscale image showing the profile of a gradient interpreted as greyscale.
The Profile node does not accept any input.
The Profile node generates a greyscale image showing the profile of the specified gradient.
The Profile node has the following parameters:
the drawing mode of the profile: fill will fill the lower part of the curve and curve just draws the curve
the gradient whose profile is shown
the width of the Profile to be drawn
The main purpose of this node is to visualize gradients to be used in other nodes to create depth or normal maps. The gradient can easily be copied to a Gradient or Colorize node using drag and drop.
