Tangential problem is crafting a transparency, reflectivity or emission map for a 'well wrapped' prop, typically a complex OBJ with equally complex textures.
As some UV mappers allow parts to be moved around to minimise 'wasted space' on a texture, finding eg interior mirror or small bulk-head lamp can be fraught.
Unless you're fortunate enough to spot the shape, may come down to a 'binary chop': So, apply a 'half+half' painted image crafted in eg free Irfan view. Half-paint the portion that hit target, repeat until located...
My worst-case was seventeen (17) iterations to locate a few dozen pixels in unexpected part of a very busy 2k texture. A smear rather than a shape, it could not be found 'by inspection'...
