for asset scale you need to be really careful due to the physics, best way to check is to add the 3rd-person template to your project then you can compare your asset to the size of the maniquin.
i’ve no idea why the advanced vehicle template has a half scale vehicle amybe that was the only way he could get it to work with the avaible code !!!
ps would it be posible to make it a code plug-in that way we (testers) don’t need the github version of the engine
