Strange Texture Glitch

Sorry in advance if there’s an obvious reason for this visual glitch, I’m very new to the software.

Some of the textures I import into UE4 seem very glitch-y from a distance (the glitches can also be seen in the content browser, via the thumbnail).
I’ve noticed this appears to be the case in-game too, for example here:

Water Tiles Up-Close
Water Tiles Zoomed Out

Some of my textures aren’t bad in-game, despite them having glitchy thumbnails (at times), though these animated tiles for example, are well… pretty much unusable in their current state.
I export my textures from Photoshop as PNGs, if this information is useful.
Thanks in advance!

There’s no obvious reason I can think of. It would be useful to see how you’ve got your material set up, could you get a screen shot?

Absolutely, here’s the material set-up(as you can see, the glitch is visible here, too).
I’ve heard some people say Targa files are ideal for UE, is this true? The texture is 256 x 256, and appears to be completely fine when opened with any other software, and again, when up-close in the game is fine.
Thanks for the quick reply!

TGA files are fine, I use them all the time.

does the texture look ok if you open it in UE4?

May be corrupted mipmaps.

What type of image type are you using?

Also, would you mind sharing one of the textures and I can take a look as well.

Thanks!

Here you go! It’s very simple as I say, just a 256/256 png file.
Also , as I said before, when opened in any other software, it’s fine. It’s when it’s in UE4 that I start seeing problems.
This isn’t a seamlessly looping texture btw (it’s a bit off where it’s meant to loop). I just wanted to test the Panner in the material editor. Thanks!

OK, so I’ve saved the image out again as a TGA file, and the problem seems to be gone. Whenever I try to re-import the original PNG, it seems to work correctly now. It may have been a corrupted file after all!
Sorry for wasting your time guys!

Not a waste of time. :wink:

Glad it’s working for you now.

happened to me before, usually all it takes is restating editor or reimporting file to fix it, i guess that artefacts are caused when texture loaded incorrectly or something :slight_smile:
