Maybe you forgot about .ini files in enbseries folder? enbeffect.fx.ini for example, they contain parameters of shaders in such case and better replace them too.as example Mojave enbeffect.fx have a nightvision patch the other preset not. the parameters and shader thing in the files a are different
About enblensmask, i just remembered, its similar to enbpalette and loaded by the mod internally. I know how to make it updated at same time when "apply" button pressed and if you need this, i can make an update for the mod.
