When I switch the weapon on my player, for example, from rifle to pistol, it seems like the arms disappear upwards. This looks odd in the gameplay. Is there a way to change this, so that the arms fly downwards, for example? I've tried to create a screenshot of that
Looks like you need to create or tune some presets, look for offset. The other thing is to closely match the origin of the arms to the demo characters origin, but you'll still need to tweak presets, just not as harshly.
