3D grass shader to mimic large grass field

[Zhi]

Hi JvdBosch,

What does the trans.setScale([0.2,0.2,0.2]) do. Does it rescale the node or the texture map?

In my code, I have more than 2000 small ground patches (2m x 2m) with the same texture. I have another huge ground patch (100m x 100m) which has a different texture. My question is whether I can blend the two textures as if they were applied to the same node (i.e. the 100m x 100m patch), using the texblend function you suggest?
