Author Topic: new gradient map filter  (Read 14830 times)

Hi, 2 questions:
1. Is it possible to orient the new gradient filter to world position normal?
2. Is it possible to rotate the gradient filter.

Gradients are needed in stylized texturing.
Most common is top to bottom (not left to right).
Gradient projection is important because most of the time the gradient follows world space.

Typically you would want to do a top to bottom gradient, photoshop style.
3D coat does that for example.

The gradient filter only goal is to remap the value it gets as an input.
This means you have to figure find different ways to generate your gradient first before modifying it with the filter.

Try something like this :
- Add a generator effect to one a your layer
- Load the "Grayscale conversion" generator
- Load your position map into its input
- Change the parameter "Grayscale Type" to "Green Channel"
- Add a filter effect and load the gradient filter

This setup will give you a top/down gradient that you can modify with the gradient filter. You can also load the world space normals to get other types of gradient. You can also use the "Distance" generator to generate a point which fade based on the distance, to generate a gradient more localized and volumetric on your mesh.

Don't forget your log file. It can be exported from the Help menu of the software.
