What is a ramp texture?
The ramp texture is a quick way to create gradients. You can specify the color(s), distortion and gradient type. Colorful ramps can be added to your color channel and grayscale versions work well in defining transparency or reflection.
What is ramp shader?
The Ramp Shader is a material (shader) that you can use for extra control over the way color changes with light and the view angle. You can simulate a variety of exotic materials and tweak traditional shading in subtle ways. All the color-related attributes in the Ramp Shader are controlled by ramps (gradients).
What does the ramp setting let you add to a material?
What do the ramps do in ramp shader?
All the color-related attributes in the Ramp Shader are controlled by ramps (gradients). Graphs let you avoid complex shading networks by making certain looks, like toon shading, easier to achieve.
Which is the right side of the ramp?
The right side of the ramp is the color where the normal points directly towards the light. The center of the ramp represents the point at which the surface normal is perpendicular to the light. The left side is the color where the normal faces directly away from the light.
How is the color of a ramp determined?
The position along the ramp is determined by the angle of the surface with the view direction. The right side of the ramp is the color where the surface normal faces the camera. The left side is the color where the surface normal is perpendicular to the camera. The total light brightness is used to index the ramp.
How do you map a texture to a ramp?
Click the handle above the ramp to select it. Right-click the Selected Position attribute in the Attribute Editor (or Ramp Editor) and choose Create New Texture to map a texture. After you have mapped a texture to the position of a handle, the position field becomes locked (the text box appears yellow).
