I’m not sure what is going on, I am trying to Import a hud we had designed in photoshop. When I attempted, it took me a minute to find it in my computer after I had exported the file from the zipped file (stating this in case this is what is causing the issue), when I found it however it popped up with a message stating, “The texture you are importing is not a power of two. Non Power of two textures are never streamed and have no mipmaps. Proceed?” Now I don’t want to import this if it is not going to be able to be used as an asset to the game because it is not formatted correctly. Any help right now would be nice? figured this would be a rendering issue because of the mipmaps and streaming aspect of the message.
Make sure that your resolution of your texture is always like e.g 512x512, 127x127,… 
Is there a way to alter the resolution from within the engine or do I have to do that via photoshop? (Just out of curiosity) also it came in with a red background and there was a white background when I extracted it, does it need to have a black background to keep the background from showing up?
As far as I know you cant permanently do that in the ue4 (just in the material) -> so you will have to change it in gimp/photoshop/…
what about the background issue? My boss has a bit of a question cause he is doing the photo shop aspect is that like a mandatory size or can it be brought up? say instead of 512x512 can it be 1024x1024?
You can choose every size that you want, but it should be in “power of two” -> but always keep the textures as low res. as possible (e.g dont use a 4k texture when a 512x512 is good enough)
