Not sure what you mean by that. Most clerics already use the cleric animation, though conversely, a lot of fighters do not use the fighter animation (many guards and such use the cleric animation). There is a component to fix that already (#25 Humanoid Animation Fixes).
I installed that already, no change.
It seems I have problems making myself understood, please bear with me patiently for a while and I will try to explain what is wrong in my game (and maybe yours too)
Several playable classes don't show the correct animation when wearing armor. Female human clerics for example, use no armor animation at all, and they do have animation for all 3 kinds of armour (Leather, Chain and Plate).
Another example is the fighter & cleric classes (male human/all elf genders), they share all animations as base but the 4th armor animation (plate), they have an unique entry for that one in the 'BAM' folder and what they are using is the fighter animation for both classes.
The same probably is happening to dwarves/gnomes/halflings/elves and so on.
And I suspect some of the wizard animations are also unused.
You can see the animations for human male cleric plate armor "CHMC4A1 to SX" and compare with a male human fighter "CHMFA1 to SX" see the difference?(Using Near Infinity to browse the files)
The mod is intended to fix that? How can I edit those myself to use the correct animation?
Do you understand me now?
