Headlight bumps (need help..)
show user profile  Kiwi2703
Hello there :)
So, I have a little problem modeling headlights for a car. Actually, I need help especially with one part.
I have no idea how to make those "stripe bumps"; I highlighted them here:
I tried making bump maps but I just couldnt position the stripes to be in the place they are supposed to. I tried making the bumps manually but the positioning is really hard, too.
Do you have any practical solution for this? It would really help me! Thanks in advance.

PS: I was thinking about creating the bumps as another object (a little stripey-elipsoids), and wanted to ask if it was possible to create them along a line I draw (with proper rotation). I hope you understand what I mean Thanks!

Normal mapping would be the way to go.

You could opt for geometry, model the base shape of that part of the light, edge-connect it with an inset and select every alternate edge, pull them out a bit - using the normal constraint might help.

For your second method, you could create a spline along the shape of the light, then use either the Clone plugin (free from iToo Software) or the Array/Spacing Tools (native to Max) to duplicate your ellipsoidal shape across the light.

There are many ways to do this. Probably the easiest is to make a bump map. You can do this in photoshop or directly in max. The photoshop method should be self explanatory.

1. Make a test plane and give it a standard material.
2. Under maps -> bump, choose gradient ramp. Then copy the parameters I've shown in the pic. Make sure to tile it a lot of times on the x-axis (which is "U" in UVW space).
3. You can now make lots of segments in your plane and apply a bend modifier. Again, copy the parameters shown. Now you should have something similar to my pic. Note: I duplicated the bent plane and flipped it over to create the dual bend (just for demonstration purposes).

Now you can copy that gradient ramp map and apply it to any other map you created (by pasting it in the other material's bump slot).
