Character dosent look right

Hi, i made my games main character in Maya, i used HumanIk and skinned it to that skeleton, then i retargeted it to the Unreal engine skeletton( (i also changed the base pose to “A” pose).
i want to be able to use the animations that are in the engine + buy som from the marketplace as i am not a good animator, my animations are robotic and twithcy :slight_smile: My problem is, it works but the character dosent look right, the chest is kinda pushed forward, and also the knees. Is there anyway to make this look better? I suspect there might be a height difference between the skelettons. Also my character is very low poly compared to the unreal mannequin. Any ideas?
