Select an Image Format for the textures and click Assign Textures. The Assign File Textures window opens.
Enter a size for the texture in the Size X and Size Y boxes and click Assign Textures. The Keep Aspect Ratio option ensures that the proportions of the image are maintained. Turn this option off if you want the width and the height of the texture to be different. Note that the texture size is currently limited to 2048 x 2048 and must be a power of 2 in each dimension. Larger textures require more memory. Textures larger than 512 will yield slower performance.
