I begin by adding a fill and turning off all the channels except color
I then choose a base color for the model
For the gradient, I add a new fill layer and change the color
I add a black mask
I right-click on the black mask and add a generator
I will use the 3d linear gradient
The balance for the generator will adjust the amount of gradient on the top and bottom of the model
The contrast determines how sharp the blend between the two gradient colors will appear
If I change to the position map, I can use the color pickers to choose where the gradient starts and where it ends [go back to material]
This is a quick way to change the gradient but it doesn’t offer much control
I can however, change the position end to a solid black
For the position start, I can change the position start color to a bright red (which is the X-axis)
With the balance at 0.5, I now have a perfect gradient from left to right
To invert the gradient colors, I can change the invert option to true
If I want a linear gradient that is top to bottom, I change the position start color to a bright green (which is the Y-axis)
With the balance at 0.5, I now have a perfect gradient from top to bottom
To invert the gradient colors, I can change the invert option to true
If I want a linear gradient that is front to back, I change the color to a bright blue (which is the Z-axis)
With the balance at 0.5, I now have a perfect gradient from front to back
To invert the gradient colors, I can change the invert option to true
