Object translation definition

[pmmATT]

Hello,

The canopy in one of my airplanes slides 5" while closing along the 3 ds Max WSC Y axis and I would like to transfer this movement into RF 5.5x.

Perhaps NUP_MaxTranslationY=5 defined in 3 ds Max object properties will work?

Thanks,
Matt

RF has no linear movement. Only rotational. The easiest way to achieve the movement is to move the pivot of your canopy far below the canopy itself. Then when the canopy is assigned in Rf to a movable pod you will be able to put a small x rotation (I.E. .4 degrees) you will get what looks like linear movement in the Y.

You can also use 2 dummy objects in Max, set up one behind the other with the canopy in front of them. Make sure the dummy pivots are oriented the same way as your other pivots. That will result in true linear motion for the canopy, with 2 movable pods (plus the canopy) in RF. http://www.knifeedge.com/forums/show...&postcount=103

You can also use a multiple pod, "scissor" method to get true linear motion. It takes three pods but it can be done.

Picture a pair of scissors standing points down on the table. One point is fixed in place (only rotates) and the other slides across the table linearly. To do this you need one pod at the fixed point, one at the scissor hinge (use a Max helper object here), and finally one at the object you are sliding.

Yup. That method! Doug told me about it a while back.

I will try these tricks.
Thanks

I've done this on the original B-1B Lancer I created for the crew entrance ladder. To make it easier to setup the physics in the RF editor, I make actual visible helper objects with pivot points set where needed. I import that model into RF to setup the initial physics. Then, I export a new version with the dummy objects replacing the visible ones I used to setup the physics. I name the physics model with (physics) so I don't get confused importing the finalized model into RF.

Matt, I was thinking of doing something similar to position the dummy pivots.
