shit about reflections

I had a problem with my scratch-wheel's reflection ingame. In ZMod,it worked all OK tho. So, i mapped the rim,cause i wanted it mapped lol. Then, i exported it,and weeeee,it all worked. So i thought that maybe this caused the reflection error on my subwoofers. And i mapped them too. And yeee! They work now as well. So if some of you would start to make a scratch project,map it first. No matter,how, but it needs mapping.
