After I resized image and imported into unreal engine I noticed that it has artefacts. I tried both gimp and photoshop and different algorithms for resizing image. But I don’t know where is a problem

Hello Asha, your post lacks quite a bit of information.

  1. What kind of artefacts are you talking about? those lines?
  2. Did the texture originally have an alpha channel texture you forgot to export?
  3. Did you save it as .png (UE4 and .PNG have issues with alpha channel situations, you might want to try .TGA)

Those lines are caused generally when you save a .png with alpha channel, which as i said before does not work properly for some reason with ue4 (photoshop issue), and it will then try to dilate all the alpha channels with edge pixels of the information from whats there.
