Hey Guys,
Nice challenge.
I use the full 90minutes for this texture. I really wanted to make it look like it was lit from behind with fluorescent lights. So most of the time went into tweaking to get that effect. I would have liked to spend more time on the back of the sign and the posts.
If i was to do it again, I'd check out some good reference for this type of sign, hopefully then I'd have more time to create a spec and maybe a bump map.
I used a 512x512 Diffuse and 512x512 self illumination map. basic spec settings on the material, and rendered with default Mental Ray settings. Skylight, Omni and Directional spot.
Cheers
