What makes units able to ride on horses?

[Kraxis]

But that was what I did initially... and that didn't work. CTD...

If I understand you correctly that is.
You say I should add the line for the horse skeleton from the general? Or just as a skeleton?

[EDIT]
Found the problem... Every line in the mounted skeletons need to be added. Add one or two and the game will CTD. Now my mounted standard bearer works. Sadly he is not holding his standard upright, and sometimes it passes through the horse's neck. I guess it is better than nothing, but it is not as good as I hoped.

[EDIT2]
Setback!
It doesn't appear that the greek officer and the roman early centurion are compatible with the mounts. They become those 'centaurs' I mentioned earlier. In fact the greek officer is quite funny to watch as he goes into the combat stance with the shield in front of him (right into the neck of the horse). So obviously something needs to be done about this as the standard bearer wasn't up to specs either.

So nobody has created a Decurion (just mounted a centurion)?

The eastern musicians are great for cavalry, but I would love to mount some kind of officer for the western factions as well since the standards aren't too great (they work but the standard droops and acts a little strange at times).

I am not at all clear what you are doing with this.....

1) What skeleton are you using for the RIDER. This is the only skeleton you should be changing. The horses ALL use the same skeleton.

2) With the standard bearer...if you make him mounted, and use a cavalry rider skeleton, he naturally will be using his standard as a 'spear' or whatever. To really make that work as you want it to, you are going to have to either change the model so the standard and arm are not animated and remain fixed in position.... or else design a completely new rider animation to make him do what you want.

This is one of the limitations of using the stock skeletons for things they weren't really designed for.

I'm not certain what skeleton I'm using, I just added the mountlines from the various captains and generals to the standard bearers.
He uses his sword to attack enemies but the standard droops in front of him to the point that it touches the neck of the horse, so that during combat it sometimes passes through the neck of the horse. Looks odd.
But the standard bearers are not too bad really. What I want is the roman centurions and the greek officers (of course without the shield). But when you try to mount them like I did they just stand up inside the horse creating an odd centaur.

Earlier in this thread I tried doing what you said and it turned out that it could be done, though the results were like the centurions. So I wondered if it was possible to change a few things to make the officers actually mount the horses. I just figured that I did something wrong.

So if you know how to mount officers and centurions I would love to see a paste of it.

Just to make things clear this is what Emperor Umeu 1 was saying, it's taken from a post from a very similar thread on in the twc workshop.

Ok, problem is more or less solved.

It turns out that if you want a unit to have multiple possibilities, such as on foot or mounted, you must include all the others - like elephant, chariot and camel, even if you're never going to use them. So

type roman_centurion
skeleton fs_dagger

AND

type roman_standard
skeleton fs_standard_bearer

NEEDED TO BECOME:

type roman_centurion
skeleton fs_dagger
skeleton_horse fs_hc_swordsman
skeleton_elephant fs_forest_elephant_rider
skeleton_chariot fs_chariot_sword
skeleton_camel fs_hc_swordsman

AND

type roman_standard
skeleton fs_standard_bearer
skeleton_horse fs_hc_swordsman
skeleton_elephant fs_forest_elephant_rider
skeleton_chariot fs_chariot_sword
skeleton_camel fs_hc_swordsman

[Kraxis]

Odd... I'm positive that was what I did earlier. But now it works and that was all I wanted.

Nice, now I have Decurions too... YEAH!
