I used Actor Core Accurig to give my model a rig to control. once i was done, I downloaded auto setup for blender to riggify the model once ported from Accurig. first, the models rest pose was odd, i had to clear all transformations for it to have a normal t pose. second, when i riggified it, the model kept returning to a odd rest position where i had to clear transformation again then set as the default by making a key frame for it. finally, i started to pose the model with IK controls and notice parts of the rig didn't move, then when i swapped to FK the model reset back to the rest pose. I am not able to use IK and FK at the same time, each time i swap all posing gets erase. i tried clearing all transformation but nothing works. thank you for the help and time.
