Sims 4 Shader Lists& possibility of help on getting alpha editable hair to work?

If EA Patches, We will have hair that works properly without a workaround. The current way of workaround uses the same Shaders as glasses, which causes for the hair to essentially behave like glass themselves.

I can't say anything for the lagging because that's a very dependent thing. There's too many factors in lagging (Your System, How much CC you have, etc.)
