Quote: Image data is generally loaded into an array of width and height.. So saying you need an image of the same size and width or even a power of two is just silly. Maybe. But why is that integer types, floats and double number types in C have minimum and maximum values that are (gasp) powers of two? I invite you to peruse http://en.wikipedia.org/wiki/Power_of_2, paying special attention to the second paragraph of the section titled: Fast algorithm to find the next-highest power of two to a number in the ring of integers modulo a fixed power of two . Sure, you don't NEED textures that are powers of 2, but they appear to be more efficient. And why would I want to do anything that makes Poser run less efficiently? Just my opinion.
