That's it. In this case, i think the best solution is to use mask instead of alpha channel. Using mask, you can have transparent texture pixels, but not partial transparency; that may be sufficient for grass. For using mask in Soya, all you have to do is to modify your texture so as all alpha channel values are 0 or 255 (no in-between value).
