not really sure about crazy tao will have the same configuration as eo but you may try this
mount.ini
Code:
[1000]
Part=1
Mesh0=801000
Texture0=801000
.....
3dmotion.ini
1- please take a note if you have a mount.ini entry of 1000 or 10X0 then the 3dmotion should start with 100, if you have a 20X0 then is should be 200 or if u have 250X0 then it will be 2500 and so on...
2- weapon type. in EO we have warrior mage and paladin etc..but i will just explain about the mage weapon..mage weapon have a statring id of 440XXX
3- now you gonna add this mount motion for every weapon type(410XXX 420XXX 430XXX 440XXX 470XXX 480XXX 490XXX)u have but like i tell you before i just use 440XXX id for the guide. the rest is up to you.
4- the motion line should be like this
Code:
1001000XXX=c3/0001..... etc
1001440XXX=c3/0001..... etc
1002440XXX=c3/0002..... etc
100= mount motion
1 = male id, if female then 2
440 = weapon type, 000XXX means no weapon is equiped
XXX = movement motion
c3 = c3 folder on client
0001 = male folder, female folder is 0002 based on what eo have
immediate.ini
all the line you add in 3dmotion you gonna put it here also under [body] header/section except its "=c3/00....." delete them all by using notepad+ and use regex expression to search and replace(only if you wish to have easy works

)
thats all..if you found the character is not standing on the mount but the mount is just freeze while you moving. add some line of your mount in mountmotion.ini as example of 1000 or 10X0..
Code:
1999100=c3/Horse/801000/100.c3
to be more clear about this. just go to that file and compare that to your mount.ini later on you will get the idea how it works
