If one wanted to make black wheels into chrome wheels in rFactor 1 for F1 76' cars, how would it be done ??
You could take a look in the rFactor 1 forum. http://forum.imagespaceinc.com/ The owner of rFactor 1 is ISI. The owner of rFactor 2 is S397. Different companies, webs, forums...
change colour to a mid grey and use a chrome cubemap, then ramp reflection(alpha layer) and specular to white - modulation of chrome can be done by reducing the white colour in the main diffuse alpha, and make sure your using the shader where reflection is controlled through the alpha layer.
