Hi Nevarim, make sure in your Armature, the Root bone is at the top (the Parent) and all the other bones descend from it. If you have any loose bones that are not children of the Root, parent them to the Root bone (Ctrl+P, keep offset), or if they are just control bones and are not actually used to deform the mesh, make sure “Deform” is unchecked in the Bone Properties for those bones. When you export the FBX from Blender, make sure “Only Deform Bones” is checked in the FBX settings.
As a side note, may I also recommend that if your game contains female characters, always portray them respectfully, fully clothed with modest apparel, no nudity or sensual clothing. This sets a positive example for the people who will be playing your game, and helps establish an attitude of respect for women. A person’s true value is not based on their outward appearance, but who they are on the inside. Too often movies and games depict women merely as sensual “objects” rather than as valuable human beings that God created in His own image. Best regards!
