Hi everyone,
Well, I am still working on the shot where trees bend due to a rocket exhaust. I have tried FEM but I think it will not do what I want (too ‘chunky’).
I would like to try the Wire solver. What I want is the trunk of the tree to bend very slightly, the branches to bend a bit more and the twigs to bend a twitch a lot - bend angle proportional to branch thickness, basically.
How can I vary the wire deformer strength or bend angle along the length of the L-System branches? I suspect this is a VERY simple thing for a Houdini TD to do, but I am not sure how to approach it. Please help!
I enclose a simple setup where I have a L-system, converted into a Wire sim, with a hard pin constraint on the base of the trunk and I made a Wind force pushing on it.
Many thanks
Varying Wire solver along L-System length?

I can see that you can generate point attributes when the L-System is created, which gives a couple of useful sounding attributes: gen and width.
How would it be possible to feed these into the Wire solver?
Let's say I wanted to multiply Elasticity or Angular Damping by that width attribute. Can that be done? How can I do that?
Any help at all would be very gratefully recieved.
Thanks!
