Change weight multiplier

How can I change the weight multiplier of all the nodes/parts in a vehicle at once?

I tried editing scalenodeWeight in vehiclename.jbeam, but it doesn't change anything.

 

I've done this with the Vanster. I was poking around in the van_body JBeam, and I changed the nodeWeight under //van body and it impacted the weight. But for some reason, it only affected the rear of the van. I guess changing the weight for the cab also would work.

 

I've tried this with the Ibishu; I changed the nodeWeight under

Code:

{"group":"hatch_body"}, 

in hatch.jbeam since it has no hatch_body file, and when I reloaded the car the front part exploded.
When I tried to reload it again, it just disappeared along with the debug screen.

However, the weight still decreased; from 980kg to 960kg.

 

Thanks.
Is there a possibility of adding a global weight multiplier (which wouldn't cause the vehicle to explode) into later versions?

 

thanks for this Gabe


who can create a utility / program to Change parameters in cars?

example.

Change engine options Drivertrain / weight / deform or strengh of chasis. etc.?

( this remember the GTA garage programs haha) but its more easy and fastly to mod vehicles ( with perms of autors)
