I seem to be having a problem applying a uvw map to an imported obj file. All the other projection types work fine. When I choose uvw and fit to object all of the sudden I get nothing. I cant see the material in the viewport or in renders. Ive tried fliping normals and aligning normals to no avail. I must be doing something wrong..... right? Any help would be greatly appeciated as I am losing my mind. Ive posted the file below.

Thanks.

Not losing your mind--the UVs just aren't set up. Each UV poly is stretched over the whole canvas so they're all overlapping.

is there a quick way to set up the UVs? I tried saving a selection of the faces and then using that as the selection for the material, but that didnt work for me either.

Thanks.

The fastest way would be to make a edge selection along the road, then make that a spline.
SweepNURB with a short straight spline.
Now you can apply the texture along the new road (Tile in Y). I tried and it was no problem.

Do you have BodyPaint? If not, Cinema doesn't have much in the way of UVW tools. My suggestion would be to go with flat mapping.

I do have BodyPaint however I havent played with it too much. Flat projection wont quite work cause I need the texture to bend with the curves so it looks like a road.

Thanks for walking me through this.

Thanks Lennart for the suggestion, but the problem is that I will have to deal with a great many more imported objects. I need the solution that doesnt make me recreate the mesh. I wish I could do your suggestion.... I really really do.

I can't think of an easy way to make those UV's go in a straight line. Maybe it's possible to do in the application you're exporting from?

If the geometry does have UV's to start with, you might get luckier with Spanki's
RipTide Obj Plugin:

With the way the file's set up, the only way I see is to set poly selection sets
all the way down the road. You can then axis the flat map to suit the terrain.

Edit:

That tex will need to be scaled way down, but will work.
I'm sure there's a less time intensive manner, but, for now .......

Honestly sometimes you have to do that, and what Lennart is suggesting is fast! Not only that you get quick UVs.

the other option is to set all points to 0 on the mesh, do the texture in Illustrator/CorelDRAW (or paths in PS) and lay it on flat. Then use a spline deform to put the road back, or perhaps a morph target.
