TexCoord Expression in Mobile

Wasnt sure if I should post this here or down in the iOS section (havent been able to test on Android yet), but I’m have a pretty severe time using the TexCoord expression on mobile. Basically, it does not work at all.

What it is doing:

As you can see, it’s not really tiling the image as it should and instead large lines are formed. What am I doing wrong? All I did was hookup the TexCoord expression to my texture sampler.

This looks like you texture have Clamp adressing mode instead of Wrap (don’t remember the exact naming though). You can change the settings by double clicking the texture in content browser.

For mobile do all your texture coord math on vertex shader and use custom uv coords slots. Customized UVs | Unreal Engine Documentation

Thanks Jenny! That did the trick. :slight_smile:
