The following question arose from this post we’ve not received an answer from yet:
Our game will be running on iOS/Android. It was suggested that we separate out all of our UI elements into separate textures. I thought that textures must be in (power of 2 sizes) such as 128x128, 256x256, 512x512, etc. Most of our UI images will be very distinct sizes. I feel as though we are wasting texture space all over the place if we have to put each in its own size with emptiness surrounding most of it. That is why I was wondering if it would be more efficient to place multiple UI images within a single larger (power of 2) texture. Or am I wrong in that we can have irregular sized texture images such as 128x16, etc?? What do the developers at Epic recommend? This seems to be a very common scenario and yet I’ve not found any documentation on the matter.
Much appreciated and thanks!
