Oh whatever, just ignore it. He probably misunderstood it, cause his Brain was already running on caffeine for the last two hours. :lol: Just kidding.

Ok, Youre right it doesnt work totally. :wink:
What else can you tell us, how many detail layers does FW use?
Ps adding some height and colour variation to the grass would be great, but you should only do that once youve done your wind effect.
An idea would be to use a colour lookup texture, according to which you set the ambient color of a grass blade/batch of grass blades.

Hmm.. its a little hard to see.
Also make grass on hills more scattered and shorter than in valleys, in real world water from rainfall tends to run down mountains into valleys and the plants on the hill then get less water and dont grow as high and green as those in valley were water collects. a coupla rocks on hills also help.

If its really such an issue you can try implemeting soft particles saw a guide on it somewere. That should totally remove any issue with grass plane edges.

Yeah I know, just an idea, since loki is going LOKO (crazy) about that about that grass edge, which is hardly noticeable anymore.
