Is face texture stored in different file than rest of the body? In that case problem might be that it did not get in to x file during export. I am not sure but it also might be that x support only one texture filename per model. I might be wrong however.
btw: what did happen to him, "his scale" seems to beat even one used by antic sculptors
His face is stored in different file but console says that it loads that file ;/ and yes, he is pretty small but it's 2 seconds to make him big so there's no problem about it
