Gradient maker is a easy to use and handy tool for generating simple gradients in Unity on the fly without need for external 2D applications.
This script was created primarily with ramp-generation for shaders in mind, although it's applications aren't limted to this. Need a circular sprite with a specific falloff? Need to define a ramp for a shader? Rather then iterate back and forth between photoshop, manage the whole process inside of Unity.
To use: simply select 'Add Gradient Maker' from the 'Assets/Create' menu and the custom inspector window will popup and you can start creating gradients.
Choose from horizontal, vertical and radial gradients with a real-time preview of what you're output will be.
Once you're happy, name your gradient and click save. The output image will be located in the '/Assets/GradientMaker/Gradients/' foldder
This is the first and most rudimentary version of what this tool could become. I'm more then happen taking feature requests and suggestions, so please let me know of any way this could be a better and more flexible tool.
This will always be the 'Lite' (and thus free) version of this tool, mainly because the implementation isn't as flawless as it could be. If there's the demand for it, I'll publish a 'Pro' version with a much more comprehensive feature-set and custom editor window.
