Hi, just got this asset recently and had no issue integrating this with my project except for one issue.
I am using the Arms Only 2 method. My guns come from different asset packs, but the skeleton (mannequin arms) is still the same, however one of the particular skeletons seems to have a problem with the two bone IK despite being the same skeleton as all others.
I had closed my project and it was working, but when I re-opened it, the arms were twisted and pointed the wrong direction when the two bone IK was connected with the animations specific for that gun (all other guns works perfectly fine). I deleted the animations and retargeted them again through different ways and tried again through the originial way I used and everytime it does not work, the arms are twisted and not moving to the correct position.
I was wondering if there is anything that you think might be causing this issue? Thanks.
