I'm almost done with my DMI lot, but this is happening: I get these lateral "scratches" across the roof. And there not edges either, I can't just click and delete them. Its almost like BF2's "Z-texturing" (when two faces are overlapping).

Does anyone know of a way to fix this?

Those look like invisible edges on the polygon. You can fix that in XSI once it gets there, by turning the edges.

I'm willing to bet you moved that pillar at some point, and even if you didnt, rep is right.

Post a wireframe just in case.

Well, I can't get XSI. My parents and I have tried already 3 times and it still won't work, so they said not to try again (thank [insert ceiling cat here] for the Request Thread). That's why I want any imperfections dealt with in this stage.

Well, what I did was copy and paste those bars on to the face then moved them, but these "invisible edges" are qwerky. I even did a test just using the Pull/Extrude tool on a separate block, and the same thing happens once they're textured.

EDIT: Wireframes below. After experimenting a little bit, these things don't appear on the monochrome (default) texture . EDIT2: I've deleted the bars from my building, instead I'll use short walls. However, I'd like to see if there is a cure for these lines, in case I ever come across them in the future.

When your bar geometry is connected to the floor geometry you're just creating excessive triangles anyway, it's best to leave them disconnected especially for a game model.

Is that how Sketchup works? I thought that was only for XSI...
Well, thanks Ace! I'll keep that in mind in the future.

Turn on 'Hidden Geometry' in the View drop-down menu.

Can you see the edges of your scratch then?
