I'm new and I'm trying to learn how to make a toggle for the alpha channel of of the viewport display material so that I can set a shortcut on it. I can't do that by normal means it seems. So I'm trying to make a script for it. I already know how to make an addon. I know how to do something like this in Maya but I can't figure it out here in Blender!
What would be the line of code I should use to make this happen? I'd like to toggle between a value of 0.2 and 1 with the said command.
You would have to implement an Operator for a shortcut. I'd suggest ask for the alpha value and set it based on a certain condition. Following example is based on our famous operator_simple.py template that comes with Blender (Text Editor > Templates > Python > Operator Simple):
bl_idname = "object.simple_operator"
bl_label = "Simple Object Operator"
def poll(cls, context):
return context.active_object.active_material is not None
def execute(self, context):
# Get viewport display color
diff_clr = context.object.active_material.diffuse_color
# Get the alpha component and set it
if diff_clr == 1.0:
diff_clr = 0.2
diff_clr = 1.0
