You fixed the white weapons, but if you load up Kaldarasha's option in the Battle Models - Characters, you'll see that the weapon hilts aren't being gripped and floating slightly off the hands.
Yep you are right... the buster sowrd's hilt is a bit lower than Could's hands positioning :/ am I also seeing that Cloud's left arm is out of place too, this seems to be a thing with the skeleton perhaps one of the files I moved to get the mod to work. I got a back up copy of the unpacked Iro so I could go back to play with the files and work with it until everything is in place
---Edit---
No the problem with the left arm wasn't that it was out of place it was that the shoulder plate was gone I'm once again moving some archives from one to another, managed to fix the Buster Sword just by moving the "rtck" from Mike to Mike + Millenia, seems that pack got the Buster from Millenia instead. Now it's time to work with the Ultima Weapon.
Ok that was strangely easy to fix in the end, which hey, I'm glad it was. using the back up copy I had from the open iro I decided to copy the archives one by one and try the models. it seemed I only needed to copy the "rtaf" file from Mike's part of the pack and of course "rtck" file for the correct buster Sword and Ultima Weapon worked perfectly with effects and all, no white textures or broken effects and the model from Kaldarasha works perfectly as well. I'll upload the new modified IRO file and put it on the first post. thanks for pointing this out EQ2Alyza
however Kaldarasha's Cloud Battle Model animation seems to still be slower than the rest for some reason, but other than that all should be good now.
just for the sake of it, here is the new modified IRO:

Not all is good... I've managed to fix Kaldarasha's Model missing the shoulderplate and not holding the swords as it should, however this made the BS and UW turn white for all the other options... it still works on Kaldarasha model and Bloodshot - Avalanche Edits so my guess is that classic and the models which images show cloud with a buster sword, take the texture from another Id and that I cannot fix since I don't have the tool for it and the one i got from here is not working for me saying it's missing some file that didn't come with the download :/
