Hi guys,
I’m having an issue where all of my textures look terrible in the project. This wasn’t always the case, it just seemed to happen all of a sudden. I think it may have happened after I built the lighting, but im not sure. There is nothing wrong with the material itself, as you can see the textures look fine in the viewport. It is only when I add them to the level that the textures change. Any help is appreciated. I’ve attached 2 pngs.
Hey!
As you said it might have happened after you hit Build Lighting. For static geometry, marked Static in the Details panel, a lightmap texture will be baked when building lighting. This texture is baked on to the second UV channel of your object and its looks are HIGHLY dependent on the quality of that unwrap. In your case the object has become quite darker which may be a result of overlapping faces in that unwrap.
To check how that UV channel looks you can double click your asset in the Content Browser to open up the Asset Viewer. Then on the top row there a UV button with a little arrow that will allow you to look at the different UV channels. Recommendations for a good lightmap unwrap are - absolutely no overlaps and sufficient space between UV islands.
Hope that helps!
