Hi guys.
 
	I made ash geometry and texture.
 
	I have two textures of using color and glow mask.
 
	Then I use them on Principle shader.
 
	Base texture color and alpha is alright.
 
	but I need another mask for glow.
 
	 
 
	I tried to use Emission by Texture. This is what I want for glow mask.
 
	How can I export this texture to vex variable?
