Questions regarding files

Hello! I’m new to Unreal Engine 5 and I have some questions about files. I just want to sort this out once and for all and get a professional answer.

  1. What format is recommended for textures? I heard somewhere that the best format is .tga, but I don’t know if it’s true. Or is it better to use .png or .jpg?
  2. When attaching a .png texture to a material in UE 5.5, the texture becomes brighter, what could be the problem?
  3. What resolution is recommended for textures? I use 2048x2048, but is it possible to use a higher resolution, like 4096x4096? Is there a need for a certain resolution, or is it at your own discretion?

  1. PNG ( certainly not JPG as its lossy )

  2. It doesn’t :slight_smile: Does it do this with just the color plugged into the first pin?

  3. If you literally just use the texture on a wall, and put the camera right on it, there’s never really any point in having more than 4k ( 99% of the time 2k is fine ). If you’re making a prop like a brick, then why use more than a tiny texture, because you just can’t see it. So it really depends on what the use case is.

If you want a big wall, a bigger texture is not the answer. Understanding how to use noise and combining other textures is the key to non-repeating patterns.
