Hello blenderartist community,
First of all im new to blender and want to say hello 
Im aware that this topic doesn’t match the technical support for blender by 100% but I want to ask anyway.
I want to relate a psa animation file to a psk mesh file which are exported from the game Life is Strange (it’s Unreal Engine). The psk file is not exactly correct but I can manually correct it (scale it down to 1%) after importing,
everything is fine here.
For the psa file it takes some minutes to open it but the animation is totally destroyed after importing.
(For each keyframe the animation is glitching to distant coordinates).
For the first moment I thought I can go to the graph editor and downscale each animation line to 1 percent too. But
this method does not work here^^.
I dont want to ask you guys to fix the importer but can you give me some advises how you usually import psa files ?
And what are your common steps after an extern importer fails ?
I heard about older blender version which worked (But I haven’t figured out which version to use; I use 2.77 a).
(Actually I don’t know if the rules on this forum allows me to name the used importer).
Thank you for any reply.
