Gradient Shading Node
Apply gradient shading to a material.
Gradient Shading Node
Method #
This node applies a gradient to the shading of a material node. This can be used to deform, recolour and change the lighting on a mesh.
From the image :-
- A - Mapping type Object coordinate
- B - Mapping type Object Output channel local position
- C - Output channel Texture coordinate Shader pass vertex
- D - Output channel RGBA with alpha blended material
The output of this node can be connected to other shading nodes, to build up a more complex shading system.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
Parameter Details
Position X Toggle inheritance of the X Position from the parent.
Position Y Toggle inheritance of the Y Position from the parent.
Position Z Toggle inheritance of the Z Position from the parent.
Rotation Heading Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank Toggle inheritance of the Rotation Bank from the parent.
Scale X Toggle inheritance of the X Scale from the parent.
Scale Y Toggle inheritance of the Y Scale from the parent.
Scale Z Toggle inheritance of the Z Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control how the shading is used on the material surface.
Parameter Details
Mapping Type What kind of mapping is to be applied.
- World Position : The position of each vertex relative to the scene world space (most commonly used with spherical, planar, perspective mappings).
- Object Local Position : The position of each vertex relative to the objects local space.
- View-Space Position : The position of each vertex relative to the cameras view.
- Texture Coordinate : The position of each vertex relative to the objects texture coordinates.
- World Normal : The world normals after transformations are applied.
Output Channel Which channel will be affected by the fractal noise.
- Colour RGBA : Output colour & alpha channels
- Colour RGB : Output colour channels only
- Colour Alpha : Output alpha channel only
- Normal : Output to normals
- Texture Coordinate : Output to texture coordinates
- Position : Output to texture positions
Blend Mode How the new texture or deformation will blend with the current object. see blend modes for more details.
Shader Pass How the final modified shading is applied to the shape.
- Vertex : The shading is only changed from vertex to vertex.
- Tessellation : The shading is applied as the model is tessellated. only functions with tessellation enabled in connected objects.
- Pixel : The shading is applied per pixel in screen space, so it will always be applied optimally.
Blend Amount The amount the generator is blended with the output.
These properties control attributes for generating the gradient.
Parameter Details
Min Position Minimum gradient position.
Max Position Maximum gradient position.
Power Change the gradient of the falloff.
Axis Axis the gradient applies along.
