I want to model a locomotive, and hope to achieve a little specular effect using a normal map. You can see the very small bumps and indentations that make the loco bodyside bumpy and nonuniform. This would obviously be a huge waste to physically model, but would be interesting to see with a normal map.
How would I achieve these very slight dents without manually manipulating vertices? I hope there’s some modifier, but if not, it’s OK.
