I am struggling a bit with these .uop files right now. Currently I use map0.mul on the server side with ServUO and map0LegacyMUL.uop on the client side. I have the converter plugin for UOFiddler and it seems to work fine.
The need to convert between these formats seems a bit cumbersome to me. Are there any plans for ServUO to support UOP files?
Hmm, I've created a custom map with dragonmod11 and converted it to map0LegacyMUL.uop with the UOPPacker plugin for UOFiddler. It looks perfect in the client, but as soon as I hit an object I fall through the map to z: -86. If I use map0.mul on the server instead, everything works as expected. Because of that, I assumed that ServUO only supports MUL files. Maybe something else is wrong.
