Saying this is “dumb” isn’t helping me with the problem.
A) Are the files in the right folder?
B) Is the model path to set the model correct?
C) Is the file being sent to the client?
D) Is the Custom Skin Compatible with the object? (if by custom skin you mean custom model)
E) Do you have other custom skins that are working and it is just one that isn’t?
I could keep going but with the total lack of information you provided, it could take a while.
EDIT: Also wrong section I believe.
