So I have a perfectly good rideable drake script. (I think) It looks like a drake and everything, but when you mount it, it turns invisible and you just walk a little faster. If it's a scripting problem I uploaded it to look at.
As far as i am aware the Rideable Drake was custom artwork so in order to actually see your character riding the drake you need to obtain a copy of the graphics and modify your mul files
it has been created before if i remember correctly over on runuo so you might be able to find it over there along with the graphics and a toturial on how to add it to your client files..
I dont know how the Fiddler Plugin for UOP works but Neo from Scriptuo released his UO-File Formatter a short while ago. http://www.scriptuo.com/index.php?topic=11071.0 In Order to Download you need an Forum account and introduced yourself.
It allows you to Unpack uop in a good Speed, then you can modify mulfiles with uofiddler by adding or replacing arts and repack it to uop.
Step 1 : Generate MulFiles ( UOP --> Mul -Button)
Step 2 : Hack your mulfiles ( UOFiddler is easy about )
Step 3 : Save your Mulfiles ( Fiddler have save Buttons and generate the new MulFiles)
Step 4 : Repack your UOP Files ( Mul --> UOP-Button )
