+			#=======================ASapphicKitsune's solution implemented by Anime Nyan
+			#======= This is for dealing with certain textures which want to use a different extension mode
+			#e.g. Clip, Repeat, Extend and Mirror 
+			#and for tricky image textures which only want the extension mode to happen in one specific axis x,y,z 
+			#or in uv map terms u, v, w
+
+			# This is if the u, v and w (we don't use w because it is the z axis) 
+			# axes of the uv map should be wrapped
+			# the same way, hence we can just use blender's extension attribute
+			# on the image texture node, because it changes the u, v and w extension modes all together
