    I'm making a map. And I'm making these tall objects, and my question is two questions, one can I make these objects blow in the wind like trees? I'm wondering on how that's done. And second is it possible to make the objects have collision, meaning when you fly through them they will cut/rip, tare? Is this possible to do?

    Object collision is possible, but you would have to Jbeam them, which would require some additional effort. :p

    Are you saying Jbeam will make it blow or cut? And I know how to do jbeam.

    cloth as far as we, the community knows isnt simulated Yet (if thats what you're referring to) but if drowsysam can make a spaceship, then anything is possible

    Cloth is easy... just make a grid of nodes and connect them, make the diagonal beams undeformable, but very low spring(just enough to make it not roll up into nothingness when you drive into it), and you can make it rip too I guess... But then you can only place it on the map as a vehicle.
    And wind isn't simulated for n/b... If it wasn't made of n/b, you could make it move in the wind the same way trees move in the wind...

    Oh okay, I see now, I'm doing the Jbeam for this objects now, but I'm having some trouble getting it all right. And it wouldn't really matter if it was set as a vehicle, will it? I mean it should stay on the map when released?

    Yes, you can place "vehicles" on maps permanently, but you can't rotate them yet.

    I won't need to rotate them. Now if I make it a cloth material, can it rip when flow through?

    Yes, if the beams are breakable, but it will only rip nicely if you have enough nodes.

    Now would I adjust beamdeform? And how many would you think it would take?

    It depends on what kind of cloth - do you want it to stretch permanently before tearing? If not, set beamStrength to be lower than beamDeform. Then it'll just rip.

    Just make a grid with a high enough density, maybe 0.2m between nodes? I'm not sure what you're making exactly.

    I just want it to tare when flown through. And stretch a little bit. Here's the model, the top point and down to the base will be the cloth material:
