Personally I agree its better to use DIR_ ,
What the issues is in the builds I have been doing recently ,
is that for example ,
if you use DIR_ on the arms front and rear ,
this movement is controlled by the engine , on the hub positions ,
this is fine for HUBS/ then ARMS ,
but then anything on the chassis side , wouldnt be possible to do ,
like heave springs and rockers ect
Maybe on future builds we can use the DIR_ it has way more features ,
but mixing DIR_ and animations currently I do not see the outcome ,
but it is a better way personally to make the cars
