Hello All...
I'm looking for some tips on applying road markings at intersections. I'm using Gradient Ramp and Masking to create road lines on the main part of the road, but scratching my head on what to do at the intersection where the lines fillet together and there usually are other markings as well such as stop bars, lettering, crosswalks, etc...
My thoughts so far are: 1) create additional polygon geometry at intersection and use multi/sub-object materials with map channels and different UVW's. 2) Create additional objects that sit on top of the road surface that will get the materials or 3) Photoshop the intersection linework in an image and then apply image to geometry with Unwrap UVW's. I'd love to hear some input on how you might accomplish this? Hopefully there are some easier and more elegant ways to accomplish this.
One other question... How do you guys apply multiple bump maps to an object. For instance, sidewalks? Using a bump map for the texturing the concrete and another bump map for creating the expansion joints with gradient ramp. Right now I am using Composite Map in the Bump map channel and then blending the two together with different opacity and blending modes. It works, but again, is there a more elegant way to accomplish this?
Thanks for any input and attached is an unfinished image of the road intersection.
