How can I apply snow textures to land?

[Rolig Loon]

You'll find a selection of ground textures in the Library folders at the bottom of your inventory.  If you are the sim's owner or have manager abilities, you can apply any ground texture in World >> Region Details at the Terrain tag.  You cannot apply land textures at the parcel level.  It's the whole sim or nothing (unless you apply it to a fake prim that sits on top of the real land surface).  See >>> http://community.secondlife.com/t5/English-Knowledge-Base/Editing-terrain/ta-p/700061

If you do not own a sim (that's the majority of us) and you want to change your land to snow, you can use a prim and apply a texture to it. Even the mainland can have snow this way and places up in the air. You can also find snow sculpts and mesh hills as well as ice skating rinks etc. Try searching the Marketplace for snow under "landscape".
