Like a total noob about this framework, I have two problems with the Shade-C v0.91

How I can add multiterrain shader to my hmp terrain and how add colormap, shadowmap and textures? I found two action fx_terraintex and fx_terraintex3. Which I should use?

Second I have a problem that the grass does not receive shadows from the player and the trees, and also my terrain don't recive shadow from player, only block and some static models.
