So I found some interesting info on reverting the old skeleton models. However, there is some various issues with client version and server settings. Here is what I found so far.
The new skeleton models can be reverted to old by simply replacing them with the following sql command line;
Code:
update npc_types set race = replace(race,'367','60');
This replaces all new skeletons (367) with the old ones (60). (To revert back, just run the sql command again reversing the numbers.)
The problems is, in clients other than titanium, the animations do not work for the skeletons, they just move around in a frozen state, arms out-stretched. However in titanium, they are back to old skeletons as normal with their animations working fine.
I will keep playing with and searching for other settings, just wanted to note what I found so far.
