Retargeting Fortnite Models


can anyone help me fix this im trying to retarget a fortnite model in unreal and i keep crashing please help if anyone knows

I’m trying to do the same but have gotten further than you, so far i have been creating ik rigs for the model I exported from blender and auto assigning chains and auto ik rigging. This works until I try to actually retarget any animation. Then the model floats 300m in the air. im stuck at this point
