Actually Hannes I was referring to the Variation Colour as I've found it a bit rudimentary, but when a large expanse of veg is involved some variation is needed if you've only the Free version and 3 pops, and it is great for that. Choice of colour range is important and I've yet to try a Surface layer network in that slot...hmmm...why not he asks himself....The Fake stone colour variation works not bad if you are using a grey or white stone, but is weak compared to the Tab in the Populator...just my opinion of course.
