  particle like obiactor
Posted by: maygdirf - 01-04-2022, 04:09 PM - Forum: Obi Cloth - Replies (5)

Hi again!

I was wondering if it's possible to treat each particle of a ObiCloth like a ObiActor, so move them in a desired position for example. In particular, I would like doing a suturing task like the medical procedure in which the two parts of a wound have to enlace using a rope. Thanks in advice.

  Friction on Moving Platform
Posted by: Oxters - 31-03-2022, 05:52 PM - Forum: Obi Softbody - Replies (4)

I have a conveyor belt set up where many panels are moving around in a loop using forces. They're basic box colliders and I added on them the obi collider component. I created a softbody object chips bag and tested it out, it bends and interacts with other objects nicely. But when it is on top of a panel, it does not move with the panel. I tried creating an obi collision material with high friction values and attaching it to both the panels and the chips bag, but that didn't work.

Frictionless Chips:

Normal Behaviour:

Any help with this would be much appreciated.

  Is it possible to use the fluid renderer without the fluid physics?
Posted by: ITR13 - 31-03-2022, 12:40 PM - Forum: Obi Fluid - Replies (2)

Is it possible to either use the fluid renderer on a unity particle system, or to input the position, velocity, or acceleration of the particles based on a script? 
More specific, my usecase is that I have a burst/jobs implementation of boids that I want to make look "liquidy", and is considering Obi as a solution.

  Prevent rope stretching
Posted by: Tomek - 31-03-2022, 11:43 AM - Forum: Obi Rope - Replies (1)

Hello,
I have some issues with ropes. Is it possible to prevent ropes from scratching? 
I attached a rope to two static entities that I can pick up and move. I want the rope to always remain the same length.

  How do you create a rope at runtime?
Posted by: NailEngine - 30-03-2022, 10:51 PM - Forum: Obi Rope - Replies (5)

I am trying to create a rope at runtime with a static attachment and a dynamic attachment. Much like the chain example. There is an example script called "RuntimeRopeGenerator" that looked promising, but has been completely commented out -- it looks like it's probably deprecated. Where can I find an example of how to create a rope purely from code?

Just to be clear -- I am trying to create a rope without having to create a blueprint asset in-editor; I am attempting to do everything from code.

Pregunta Problem with surface collision
Posted by: snowtv - 30-03-2022, 08:37 PM - Forum: Obi Cloth - Replies (16)

This is probably covered in the document/tutorial/other posts, but I can't seem to find an answer, so I have to make a new post.

When I set up my cloth, it works fine at first, but if I turn on surface collision, the cloth just fell through without colliding with anything.

I also tried the demo scenes, and I found out that even the cloth objects in demo scenes can fail collision when I turn on surface collision on them. However, existing demo objects that already have surface collision turned on works fine.

I did some experiments and I think the reason is on the blueprints, however I cannot figure anything else beyond that.

If someone can teach me what's going on that'd be super helpful!

  Rope Jitter In Editor But Not In Build
Posted by: VirtualCucumber - 30-03-2022, 03:45 AM - Forum: Obi Rope - Replies (2)

Hi,

I noticed when I add force to a particle it seems to jitter a lot in the editor but in the build, it is completely smooth.

Editor:
[Image: qEZ9fu2.gif]

Build:
[Image: zieaHSQ.gif]

I have an older version of this project running Obi 5 on Unity 2019 and it doesn't seem to be having this issue. 

Edit:
It seems to be an issue with the ropes mass. I know if it's low enough it will produce unwanted effects. The control points on the rope are all set to 0.05 for the mass and the rope.GetMass() is 0.6. Whereas in the older version I mentioned above, even though the rope had the same control points with the same mass given to each one, its total mass was 1.55.

  Multiple rope: Different simulation problem
Posted by: schromercy - 29-03-2022, 09:19 AM - Forum: Obi Rope - Replies (7)

Hi, i placed 2 ropes on my scene under 1 solver and i notice that they behave differently.
I want my ropes un-extendable so i configured the solver's constraint & substep count.
Strangely it is working on 1 of the rope, but not on the other one (video attached).
How do i solve this?

Hello there,
Im making a drink mixing game, and I didn't completely understand how the coloring of the fluids work. using the example from http://obi.virtualmethodstudio.com/manua...usion.html when i pour both the colors into a bowl, the end result is red
Both of my Fluid blueprints are from the link
If i can get some help, id greatly appreciate it.
Thanks
