Why i have this dark blue color on my bus model?
i dont have any materials
Half of the faces point “opposite” direction compared to other half.
In Edit mode - select all and Ctrl-N recalculate normals.
I am not sure did you meant that i need to add my .blend file. But here it is
Volvo 7700.blend (801 KB)
I understood my 1. problem where it had that lines. And now its fixed.
2. problem i am pretty noob in blender so i didnt understood how i can fix it. And well i didnt really understood that problem what you meant with it, sorry
3. is there other way to delete those vertices which dont connect anything
and one more next time i will add .blend file
and is it possible that somebody or you will solve that mesh problem and clean them so there is not so many faces or vertices or something
And thanks for your help
It’s one of the non-manifold mesh errors. Nothing Blender specific either, here is the same explained on Autodesk Maya user guide
What you want to do is to find and remove faces that connect like that. Ctrl+alt+shift+M (or select menu -> non-manifold) is a good start that points out problem areas. Select menu -> interior faces also help but it won’t find all of them. Because you can’t have an edge that has more than two faces connected, could also use that to find them: edge select mode, select one edge that has 3 faces connected and then shift+G -> amount of faces around an edge.
