Armco - Tracks

Beneath are some notes on Material creation for Armco.

• With Armco it's important to remember that painted metal and rust are both NOT metallic.
• In addition in order to correctly simulate galvanised steel it is recommended to not use a full metallic value. The easiest way to do this is to author your metal map from 0 to 1, and then set the Metal adjuster in the Material Editor to the region of 0.3 to 0.4. This will scale the metal values back to a maximum of 60 to 80%.
• Armco albedo values should be very bright since they are mostly metallic. You are going to most likely want something in the region of 170 to 210 median albedo value for a raw metallic surface.
• At present due to a lack of specular lighting at night metallic surfaces do not reflect light at night. To work around this, a low level Retro Reflector effect can be enabled. (2.0 scale was used at Le Mans).
