Weird, and you say regular mapping types give the same result? Is there a state where things aren't wrong? ie, when you first apply an unwrap modifier and open the window, can you see your objects UVs? (albeit, not mapped properly) What happens if you apply a UVW Modifier first, set it to box, and then add an unwrap to…
Yeah, when I first add the Unwrap UVW modifier, I can see them within the bounds, albiet not mapped. Adding a box Map and the Unwrap UVW has the same effect. It wasn't scaled in sub-object, used keyboard entry to get the exact size I wanted, as it is being placed in UDK in an exact space. Pivot is centred to object atm, so…
Will give this a go, my object isn't massive at all - its largest edge is about 200 generic units (UU), smaller than many other models I've unwrapped. I will give this normalize map option a go - cheers!
The only thing that springs to mind is that your object is actually massive, and you've got "Normalize Map" disabled. This will create a 1:1 scale of your UV's, which is ideal in most scenarios because otherwise it skews your UV islands to fit inside the unwrap border. One suggestion is to scale your model down, or just…
