Some problem with sailing effects
#1
Sad 
Hi,

I recently encountered some problems when using tyflow for some effects. As you can see, I have this kind of sailing ship and wanna make a sailing animation, let the sails unfold from top to bottom. Then I did the following things, which you can see in the picture below.

Only the middle of sticks will affect the sail, I try to use the birth surface node to birth the stick particles, but it seems difficult to show the original stick shape. Then i tried to use the face fracture node, but the whole stick broke into pieces.

There must be something I don’t fully understand, but I can’t think of other ways to achieve this effect. So is there any solution? THX.

Let me make the problem easier

It’s how to make the sails seem to be tied to the whole stick instead of the particle point in the middle

To answer your last question:
If you use surface test, it will test the whole surface of the pole. If you want to test just the middle, you can use object test instead (object test is basically testing the pivot of the object).
Or, if you really want to use surface test, you can just make a little sphere, center and link it to the pole, and just test that sphere. Smile
-----------------

About everything else, and looking at your flows, it seems that you are mixing 2 solvers in Tyflow.
1) Particle Physics
2) PhysX
They are different, and you can't use operators from one, and to work on the other solver (at least, not a majority).
For example: you can't use PhysX Shape with Particle bind (you need to use PhysX bind)
Take a look what I wrote here:

My suggestion is that you go through official sample scenes, Tyson provided us, and dealing with cloth.
I guess, this would be best to do with Cuda cloth (so, no PhysX at all), and use appropriate operators with it.
Then again, you could do this with PhysX too...
It's up to you to decide... just check the samples

Thank you so much and it is really useful.
I will check the link and sample scenes.
Thanks again!
