I have been struggling to get a polished metal spinner to look right on an A6M2 I am skinning so I have done some testing to find out why. After applying a pure white environment map I found the problem is that environmental mapping is not being applied to the spinner. A similar test revealed that environmental mapping is absent on various parts of all three Zeroes. Presumably EM is not applied to prop blades and tyres due to the difficulty of calculating the reflections as they turn but the other items to lack it are:
A6M2; spinner, gear legs and brackets.
A6M3; cowl guns, internal cowl and engine parts, exhaust stubs.
A6M5b; cowl guns, internal cowl and engine parts, exhaust stubs, gear legs and brackets.
