Hammer editor - npc animations question

[H.E.C.U soldier]

Hey everyone, it's me again with another hammer editor question. This time concerning npc animations avaible to be played by npc through the use of scripted_sequences.

So, in my mod I'm making a scene where few Hecu grunt npcs are sitting in an osprey. The problem is that there is no such animation for them, instead I had to use their crouch animation. It looks kinda stupid to be honest, when they just crouch with their weapons drawn. For some reason other npcs have tons of animations to choose from, but Hecu Grunts have about 20 of them and most are useless.

For example, there is a scientist npc animation called Sit_Idle01. This one would be perfect for my sitting grunts. However, when I try to apply this animation to hecu npc through scripted_sequence, instead he uses the famous "t-pose" as if he failed to play the animation.

But, if I set some scientist animations to for example security guard, he does play them. Hecu soldier however not.

So my question is, are npc animations tied to the specific npc and can be used only by that specific one ? Or it's possible to add those animations for hecu and I'm just doing something wrong ? If it's impossible to add them are there any workarounds to fix this problem ? Thanks in advance.

You cannot apply animations across different NPC types. They are used for that NPC only. You are limited to what you can find within that model.

There are some ways around this but it requires actual modifications to the models themselves. Can't be done in Hammer.

I understand, that is terrible news for me. I really need to have this sitting animation. Does that mean I'm forced to start learning some advanced, complex modelling ? Or it's not that hard and I just have to run specific software to do those animations ?

No one knows how to add custom animations ?
