Perfecto: Thanks but it's wasn't the not knowing that's the problem, it's that my Pc freezes up when I do that, it can't handle having all the textures in the viewport at once! I can't even isolate one object and do it, I'll struggle on somehow!

Actually I just tried it and it is working, but the textures don't look anything like their rendered versions and the delay on the movement is terrible!

Nope,infact when I try and put it on the high quality renderer Maya crashes every time! Need to upgrade to a super computer I think, when I win the lottery that is....
