Object Space Radial Gradient by Jens Kafitz
The Object Space Radial Gradient will create a 3d radial gradient in around a defined point in your scene.
The process of defining the pivot in 3D Space is the same as it is used for the
'Cylindrical Projection' Node:
Ensure that the Node sits above any LUT applying Adjustment Node such as sRGBtoLinar.
You can move the World Space Radial Gradient Node back under it once you completed this basic orientation step-by-step.
This will show the object position X/Y/Z converted to an RGB Value.
Since these positional values are likely over 1.0, your object will go most likely completely white.
If the icon displays 'LDR' click on it to switch to 'HDR'. This ensures that values above 1.0
can be sampled in the viewport.
of your projection
'Display Object Position as Color Value' checkbox. Ensure that the 'Offser Relative to Object Centre' Checkbox in the 'Gradient Pivot' Group is turned off.
The 'Manifold' connection can be used to feed in a coordinate system for the evaluation of the gradient.
Color for the centre of the gradient to its outside (A to B)
Flips the distribution of the color from B to A
The size of the radial gradient around its pivot
A Gain Multiplier on the values generated by the gradient
The Gradient Profile
With this checkbox turned on the Sphere will be generated at the centre of the bounding box by default and
the XYZ Offset sliders will transform the pivot relative the the Object centre.
The X, Y and Z Position of your Sphere Pivot. These values are usually obtained by sampling the position with the
A secondary offset on each main slider with a finer granularity on the slider for precision positioning
Will apply a scale along X,Y or Z of your radial gradient.
A multiplier to control the slider sensitivity on the Secondary Offset Sliders that are part of the Gradient Pivot Group.
Shows your objects position values (X,Y,Z) as RGB Values so they can be sampled with the Pixel Analyzer Tool.
