Dunno if this will help you, it's mostly the same as Rep's tut, but I always do this:
1. Copy and insert the cape (starting from MODL till it tells you to stop, you're doing this correct reading Mav's post) into another model
2. Go to the top, and use the search function. Search for CL1L.
3. It stops at the byte of C, anyhow, you used the search function. At the bottom left is an address, write this on your paper.
4. Go back to the top, and click on the byte AFTER HEDR (so not the R). Click Tools (Topbar) and then Encode Number. Tick the longint box, and type the address you wrote on a paper in the Number box at top.
5. Now go to one byte AFTER MSH2, click again Tools>Encode Number, tick the longint box and write the SAME NUMBER as you wrote on the paper (It'll probably be still in the box) minus 16. So, when i encode the longint after HEDR with
11032, then I encode the longint after MSH2 with
(11032-16)=11016
6. Save the file, and test it in Ultimate Unwrap 3D.
It really isn't difficult, but when checking my first posts on GT you'll notice I've had
a lot of problems with this. Just keep on trying, take some breaks (from like a week or so) and at a sudden moment it'll work, and believe me: it'll never fail again
