Gang,
Are their any good locations to find power of 2 textures, every time I import normal textures I get an error that’s its not power of 2… how important is it to use power of two? I’m only doing non moving graphics like a gallery of pictures in frames that the user will walk through…
Just bring your textures into a program like Photoshop and resize/crop them to sizes like 512x512, 1024x1024, 2048x2048 and so on.
You can use an Texture Atlas for your Gallery to. Just make a new picture like 4096x409 and put your Gallery Pictures in it and set your UV´s. You only need 1 Material for some pictures.
This would depend really on your end goal.
The benefit of using a power of two image is that you can adjust the mip maps (How sharp or blurred the image is from a distance) and it can be streamed with LODs for better performance.
If it’s a small image resolution this shouldn’t be too bad. If you’re using something in the 4096 range this can be a performance hit if you’re trying to keep your FPS optimized.
