These are wonderful models!

I can help you set it up, if you want 
The issue must be something other than ACE overriding your outfits though, because ACE doesn’t allow bunnies and orcs to have jobs that they can’t (in vanilla) - which also means that we don’t have bunny/orc outfits for those outfits and henceforth there’s no way we are overriding them.
What could be happening is that the different Faction outfits would be overriding the outfits you’re adding, but that also seems unlikely since the ACE faction outfits have calls for mixins from the original outfits - so if your changes are made to the original farmer outfit, for example, they should be “pulled” by the faction outfits.
So the issue must be on another level - I have a few guesses, I will take a look on the mod and respond here as soon as I can! 
Edit:
I downloaded the mod but most folders are empty - I think only the orc trapper outfit is up? Or have I done something wrong? 
Anyway, I can already spot the issue (at least for the trapper outfit)
Here’s your mixin:
{
"model_variants": {
"orc_male": {
"layer": "clothing",
"models": [
"file(trapper_outfit_orc_male.qb)"
]
},
"orc_female": {
"layer": "clothing",
"models": [
"file(trapper_outfit_orc_female.qb)"
]
}
}
}
The problem here is that you’re trying to add the model_variants
component into nowhere; when you mix into a .json file, you have to respect the file structure, which means that you need to include the higher level which is components
- and the model_variants should be inside of that. So it should look like this:
{
"components": {
"model_variants": {
"orc_male": {
"layer": "clothing",
"models": [
"file(trapper_outfit_orc_male.qb)"
]
},
"orc_female": {
"layer": "clothing",
"models": [
"file(trapper_outfit_orc_female.qb)"
]
}
}
}
}
Oh, and also - for the file()
file call to work like that, the models need to be in the same folder as the json. If not in the same folder (in your case, the models are under /bunny_jobs/jobs/trapper/trapper_outfit
while the json is in /bunny_jobs/mixins
) you have to specify the entire path. So instead of the file(...)
try using these:
/bunny_jobs/jobs/trapper/trapper_outfit/trapper_outfit_orc_male.qb
/bunny_jobs/jobs/trapper/trapper_outfit/trapper_outfit_orc_female.qb
Or, preferably, move the trapper_outfit.json
to the same folder as the models (but remember to fix the path in your manifest!)
Check if this works 
And if you wish, I can help you figure out how to make it work, feel free to contact me here, through PMs, this thread or through Discord!
