I'm trying to make a new head with this (
http://lucasforums.com/showthread.php?t=149992) tutorial, and have reached the part where you put the files in your override folder. I can look through the heads, but when I come to mine it's invisible, and I'm wondering if it has something with naming modela, modelb, texa, and texb wrong in the appearance.2da file. As the tutorial was for a male in TSL and I wanted to make a female head in K1 I think I might have tried the wrong ones, and I don't know what should replace them.
What have you named your model and texture files, and what have you set in the model* and tex* columns in appearance.2da?
Have you made sure you've properly linked your new lines in appearance.2da, portraits.2da and heads.2da, so they point to each other?
portrait.2da (appearancenumber, appearance_s, appearance_l) ---> appearance.2da (normalhead, backuphead) ---> heads.2da
