I’ve been exposed to blender for about a week now, and this is what I’ve come up with so far. It’s supposed to be an ALMS Audi R8.
I have two problems though. As you can see, there are some wierd stripes running across the entire thing from side to side. I have no idea where they came from - I’ve removed all doubled vertices but without any luck.
My other problem is quite obvious. I have no idea how to color it. I’ve looked it up, and all the tutorials on texturing ect. are waaay above my current skill level. I simply want to know how to select a certain face or area and make it a different color. Or is that impossible?
As you can tell I am far from finished (no wheels…) so any and all comments, tips, and trick are greatly appreciated!
see the wiki on Multiple Materials. You set up your material colors as indexes. Then you select a face, select what color you want it to be from the index, and click Assign. very simple.
Not sure why you’re getting the stripes, but it probably has to do with how you are using extrude. I suspect you’ve got doubled faces there. Post some wires (screen shot [control+F3] with the model in side view or top view, edge select mode), these might help show the problem. If it is doubled faces, one image in solid mode and another in wire frame would make it clear.
When you do an extrude, you move the new faces away from, not into, the mesh.
It seems that the stripes do have to do with recalculating normals outside, but I have no idea how to do that (properly). When doing that with everything selected, it only makes it worse.
looks like you have either faces or edges inside your mesh, no offense but looking at the mesh i think it might be easier for you to start again, the mesh shape is pretty nailed down, but the topology isnt, if you want any information feel free to PM and ill help you out.
if you hit ctrl+N and fix normals and you still have the problem it is definatley to do with edges/ faces being inside the mesh.
or if you have, say two faces (qauds) with another face coming out of the middle edge (2 connected vertice) you get this issue with normals
**about selecting certain faces…
add a material to the mesh, say default material, once youve done that you can go into edit mode and assign another material to each face if you want
you need more than one material to do this, you can find the material option under mesh settings in the buttons window at the bottom, just click ‘new’ and then ‘assign’ when you have the faces selected
Select the stripe vertices, and another set on one side. If you have doubled faces, they will appear darker.
Select one edge of the stripe, and scale it in a bit. The doubled faces clearly show a “z” the line goes to the right, then left, then right again.
Removing doubles will not fix this, since the vertices are too far apart for Blender to consider them doubles. While you can increase the doubles threshold, doing so would undoubtedly find many pairs of vertices within the threshold which should not be merged, which will completely mess up the mesh.
The way to fix it is to find and remove the doubles by hand. Select a pair of vertices that create part of a doubled face, and use the merge tool (alt+m). It’s not difficult, but it is incredibly tedious, so you may want to consider Daniel8488’s advice to start again.
More to the point, though, for future modeling, is to figure out how the doubled faces got there in the first place, since it seems to be something systematic you’re doing while modeling to have so many of them, so regularly spread throughout your mesh.
Thanks everyone for your advice! I think i will take Daniel8488’s advice and start again. Now that i know a bit more about what i’m doing, it should go a little smoother (in more ways than one)
