Variables#
What’s variables?#
Variables are properties that hold a value (Float, Integer, Boolean, etc) or an object (in Odyssey, this object will be Texture 2D or an array of Texture 2D). These properties can be accessible internally to the Blueprint containing them, or they can be “exposed” to be accessible externally so that their values can be modified in a 2D Editor interface.
For example, here are the variable necessary to make a specific brush:
When this brush is loaded in a 2D Editor, we can see the exposed variables (the ones with an open eye):

Object Types#
Odyssey Brush Asset Base: in this category, only the Object Reference shall be used. It is really useful when making a Bluepring Function Library to give a context of use, especially to create specific Stamp nodes (such as “Kaleidoscope”):
