Road textures and map spawn

Not sure if this goes into this forum but I think it does?

Since the World Editor got updated I can't get around it easily.

Whenever I put a texture on a Mesh Road it works fine I save it and close the game, but when I start up the game and load the map the road textures are gone. I can still put back the textures to how it was but I wanna know how I can make it put on the texture automatically.

Another thing I don't know how to do is set up the spawn for a map. The map has edited terrain and it just spawns me under the map.

I also wanna know how I can paint the terrain can't find it in the World editor
