I’m working on texturing a simple scene for an animation (not game asset) and in the process of UV unwrapping the objects. One object, the floor, is a long narrow object and when set in the typical square texture map area it takes up a relatively small amount of space. which means it might not get a large amount of pixel space for good detail.
Is there any reason to stay within a square texture map? I have the ability to make rectangles but am not certain if a square is better - maybe for the computer to calculate?
Also, what would be recommended for texture size (using a square for reference) 2048 for 4096? obviously the larger it is the more computing it takes.
