How to unwrap a cube into a LINEAR Cubemap (all sides next to each other)? Ok, I have a cube that I need to unwrap into a linear cube map like the one in bottom left:



All tutorials reference the T shape. I tried unwrap by cube projection, and then tried arranging the UVs by hand, by they're not perfectly placed. Pack islands just screws it up.

How can I unwrap in a straight line, or align them on a linear cube map?
What problem do you encounter when you try to do it manually? You could do it this way: choose to unwrap with Smart UV Project option (and a marge of 0.03 for example), then in the UV/Image Editor, choose the Vertex snap mode, and rearrange your faces holding ctrl to make them snap. Does it answer?
