Mmm, Ultima Weapon and Crystal Weapons (in tehe .p files) are made in two groups, the edge and the rest of the Sword... looks like yours game don't support that and show only one 'group'. Other Idea is that these two Sword have the edge transparent, and maybe the game hasn't support it or someyhing. Try this... If it isn't work, then the problem is about the groups..._:
Open RTCZ (Ultima) with Kimera and:
* double click on the white model
* then un 'group' section, select 'Group 0' (Or the edge group) , click on 'Group Properties'and set the transparency to 100%.
* Save the Sword.
Try that and maybe the Sword looks correctly, but without transparecies...
