Just download it and find out. I'm not going to bother
Sigh. I like to know what add-ons are/look like before I download them. I'll just provide images for other people because you're too lazy for some dumb reason.

(sorry for jpg artifacts, imgur tends to do that with large images)
There is a definite improvement without shaders. With shaders, it removes the shine but it's actually pretty good if you don't want your terrain to shine like plastic.
