Hi Jordy,
Like I said in an earlier post, try to experiment.
It won't damage your computer, at the most, it can only cause a few hours of wasted work. Saying that, it won't be wasted, as we all learn from our mistakes.
Don't get me wrong my friend, no-one here objects to your questions, if necessary, I suppose we could give you step by step instructions on texturing your droid, but in the long term it wouldn't help you because your next creation would be completely different.
In short, don't be afraid, look on the plus side, if it don't work you wont do it again.
Its when you've tried everything possible, and it still don't work, then ask. I'm not being harsh, or criticizing, but trust me, its the best way to learn something new.
Cheers
Pete.
