Hi,i am fairly new to blender,anyway i have been trying to make a 3D environment for the game engine using a plane but when i UV unwrap a texture onto it,the texture is all stretched out.How to i tile textures so they remain sharp over a wide area.
I create my environments by sculpting a subdivided plane.
Also does anone know how to blend 2 textures together on a single surface?
Thanks for your help 
try the node editor for blending textures (although probably won’t work for the GE, but for your first problem, try going into top view and press U and select project from view function, then move the verteces around in the UV/Image editor

you may need to go through some tutorials to work out how to do UV mapping. I’ve been doing blender for a while now and i still suck at them
