I got 2 questions:
First:
How can i add my own texures to the lanscape tectures?
If i try to edit textures in landscape editing inside the creation kit, noething does happen.
I tryed to locate the textures in the landscape folder, right there, where the original landscape textures are located.
But i still wasnt able to get the textures workeing in the creation kit.
Is it possible to add new landscape textures?
If yes, how?

Second:
If u jump into a river in skyrim, the player is affected by the stream and moved in direction of the stream.
If iam not mistaken, this is done by adding a script to the water mesh, but unfortunately the water meshes are hidden from selecting, so i was not able to look up wich scrpit they use...
It would be very kind if somebody could help me with this, best with an example^^
