> Am i right that the -fixed "translation mode" checkbox- refers to the added option mentioned in the V1.19 changelog?! The "behaviour of animation" option (since V1.19) is all clear to me, but a seperate "translation mode" checkbox i can't find anywhere!!!
Yes, version 1.21 fixes behavior of the option added in 1.19, it worked wrong when .config file was missed. This is 3-position option.
Reason i'm asking this is because when i choose "Force mesh translation" than every bone is having rotation only, even the ROOT bone has!
The behavior in the case of "Use from AnimSet" is identical to one used in Unreal engine (you posted here part of the official documentation). It should prevent animation from animating translation keys except the root bone. ActorX Importer uses very simple way to detect the root bone: it uses first bone from the psa file.
"Force mesh translation" and "Force AnimSet translation" variants are intended to fix behavior when AnimSet's "AnimRotationOnly" option holds wrong value - in this case user should select one of these 2 options. In these 2 cases config file is simply ignored.
