Hi, thanks so much for this. So far I could catch up. But now my speakers do not materialize with the rest. They stay white where the rest becomes orange. The speakers are in the same object and are not facing inwards (the other side aslo stays white/grey). What could be the problem? Thanks!
Oh! Hey, for some reason while I am further along the instructions, now they are orange like the rest of the case... mysterious. But solved! Even I don't know how...
My guess would be that maybe you had 2 material slots with the speakers assigned to the 2nd but with a default material or no assigned material (which will usually give a default material look until one is assigned to the slot). Glad you solved the problem on your own, though keep in mind, adding some images showing the problem (including what your material settings are in this case) would help us to help you better :D
