Hi,

to make a car for ex, in the newton, you need put it inside a group, this group have an ID - identification.

All other models in the map, if you use the newton, it make to you this identification with the others models used in the map ( just if you not change the colision group in the behavior) if you put a diferent model in the map, with out use of newton, it have other ID, and it will not work with the colision system of newton if you not change to the same ID.

Sorry But I do not know how to change the not newton models ID to work with the same ID that newton work, days ago I was looking for a deep tutorial about newton, but without success.

Sorry for the terrible english.

best regards,

Marcio
