resolution thing? what resolution are you talking about..i did however figure out that the resolution thing changes the size of the texture in the uv window.
also.. after you put the new shader on the object. when you asined the texture.. did you click on the box next to the shaders color, and thin select File, for the type of node you wanted ?
I'm asking becouse I have not seen a textue 1, tile like that in a UV texture wendow. 2, have it outside of the 1 to 1 texture space.
