Question for the OP gurus.The open plane doc from parsoft says tires "require" the rubber property to be assigned to them. However, none of the FM's I've looked at have this anywhere, and one had cement as a property. Is there a reason this was not done? If not, what's the proper place to put this and syntax? Keep your fingers crossed, I may have an inkling of what's causing the Fw series to drop so far and bend one of the wheel struts. I accidently caused Hawk's P-26 to bounce and then land on its nose when trying to fix the original tailwheel problem. It'll take a few hous of playing to see if I'm on the right track. Thanks. ------------------

if tires are copied from "stock" aicraft then the material property is usualy already set in the LOD, like with water, but if you make your own tire you should specify it in the obBodyPts as ptMaterial 'rubber it will work without this, but then you don't get any real traction as you would with rubber, if a material isn't specified on a new tire then the defaul material is cement even if this isnt listed in the proplistIP: Logged |

Actually the "bounce" in the 190s is a result of their being a wheellock on the tail wheel. When dropped into the game at start of a mission, the three brakes are engaged, that along with the DOF springs cause the aircraft to "bounce".WHat's really sad is that I know this and never corrected it.

Just bounce with me. Hehe okay the bouncing is caused by a inproperly placed collision point on the wheels it causes it to bounce. I never fixed it because I was lazy I can't believe I said that hehe.------------------

Like FJ says, its the wheelpts. I fixed it on the 190a4 but the fix never got copied over to the other variants. TS IP: Logged |

Part of the problem is also the brake on the tailwheel. I fixed this a loooonnngggg time ago on my versions.  IP: Logged |

Simply delete the tailwheel brake - problem is fixed! IP: Logged |

umm no.. at least on the a4 the wheel was being bent because the plane was dropping too far and the increased realistic weight bent the gear. Removing the tail brake did not fix the problem. TS IP: Logged |

I was talking about the default FW190.[This message has been edited by Pete Hawk (edited 04-13-2001).] IP: Logged |

If you delete the tail wheel brake you are losing alot of braking power when you apply brakes. Onlything that needs to be done is a more definite collision point for the tire. When I say definite I mean 1000's of an inch not just to the nearest hundredth I devised a clever way a while back to lift the precise co-ords of verts. Go into Max or whatever you use...Snap the verts to the area where you want the collision point to be draw a garbage polygon to all those points delete everything else but that polygone UV map it. Save it. Go into dos and edit the .lOD file you saved it as or .obj file you saved it as and just open it in dos using edit and get those co-ords for that polygon you created to the collision point verts gentlemen. Pretty clever eh?------------------
