UV map issue?

[missigno]

Hey all! Having an issue in SP after baking. Some weird artifacts are appearing all over some of the textures, more noticeably in the hub, as can be seen in this screenshot. I tried redoing the hub_low from scratch and tried baking it without the hub_high in the .fbx file, but the issue persists. Any idea of what may be causing this issue?

The only things that come to my mind are, perhaps flipped normals there?

And maybe you have an object hidden in the viewport that is coming in at render time and it’s occluding something?

I checked and it doesn’t appear to be the issue, sadly.

This is how it looks like in SP when I include the hub_high in the .fbx file:

I see red…

Make sure there is some thickness to the hub, it maybe picking up faces from the other side.

Also make sure you have the match section correct (video from ~3:30 ), that’s about intersections of different Meshes, when Baking.

👆 This was my initial thought. Take a look at your baking options and make sure you have “By Mesh Name” selected. You may also have some success by tweaking the ray distance in your bake parameters, perhaps the distance is set too high and may need to be dropped?

I fixed it! The issue was actually in the mesh itself. For some reason, I merged the two edge loops where the visual issue was appearing, but separating it again and making new UV maps fixed it. Thanks everyone 🙂

It’s such a strange issue! I just spent 3 hours trying to fix this exact problem haha. I got it close enough, but it’s still slightly there for me. I even rebuilt the entire mesh, but that edge is just stubborn.
