  How to make rod more stiff?
Posted by: fishing-rod - 01-05-2020, 12:43 PM - Forum: Obi Rope - Replies (2)

Hi,

I try to create a fishing rod but it is behaving almost like a rope. Here are my settings:

How can I make it more stiff? More substeps are performance heavy as I unserstood. Is there any documentation for all the parameters?

best regards

Triste No "Stretching Scale" property in editor?
Posted by: smackledorf - 01-05-2020, 10:36 AM - Forum: Obi Rope - Replies (2)

Hi all, as stated in title I don't see "Stretching Scale" as a property in the inspector in the Obi Rope object under Distance Constraints. I'm trying to lower it. Is this something that can only be changed programmatically? 

See attached.

Thanks!

  Glass simulation
Posted by: SylnorD - 30-04-2020, 12:46 PM - Forum: Obi Softbody - Replies (1)

Hello, I need some help with a project.

I need to simulate melted glass for simulation of glass-making. I already tried with Obi Fluid, but I understood while searching in the forum, that Obi Fluid can't simulate "solid" fluids.

So I tried with Obi softbody, but I can't achieve niether the "slow" deformation of the glass, nor its texture. I tried to recreate the effect of the plastic deformation of the dragon figurine (like in the demo video od Obi Softbody 4) on a ball, but I'm far from a good result.

Can you tell me if melted glass simulation could be possible with Obi ? I already know this is a challenge, since glass is both liquid and solid.

Thank You

  How to stack different colors but keep their volumes
Posted by: wm4583816 - 30-04-2020, 09:26 AM - Forum: Obi Fluid - Replies (3)

Hello,

Forgive my English. I am using Obi Fluid for a game. However, I am stuck at 2 questions that I thought would be easy.

Q1
I am pouring two colors in a container one by one. Then I found when I stack the second color on the first one, the volume of the first one will be smaller. It seems the gaps in the particles are compressed. Could I just keep the volume of the first color? BTW, the liquid in our game should be very thick.

Q2
The borderline of the two colors is not very smooth(We want the borderline more clear, not diffused). We tried to make the particles smaller, it got better a little bit. But the FPS will be very low. Am I missing something obvious?

Many thanks,
Meng

  Slingshot rope
Posted by: baskot - 29-04-2020, 09:40 PM - Forum: Obi Rope - Replies (3)

Hello, I want to make slingshot like mechanic but whenever I pull the sphere back it went through the rope. I have tried to make rope length bigger but still not working.

Here's the inspector panel
         

Here's the video, any help would be great thanks.

  Obi 5 Slow on simple cases
Posted by: fdpsan - 29-04-2020, 04:49 PM - Forum: Obi Cloth - Replies (4)

Hello,

I have been trying to make some simple gonfalon flags in my game with obi.
However, I'm finding that performances are not as I would expect. 
I have six flags in the scene and the more I add, the more the performance deagrades (I also tried to use only one solver which seems to help a bit)

When i am using unity cloth, the performance impact is negligeable.

Any idea ?

Hello,

I want to do as in this video.
https://www.youtube.com/watch?v=Czy6WnIWtyY

I set  to this settings.

- Rope blueprint resolution: 0.5
- Rope max bending: 0.02
- Updater substeps: 8
- Substep Unity physics: enabled



But result not the same. 
our result : https://streamable.com/3fx40b

How can do this?

  Performance improvement?
Posted by: zforest - 27-04-2020, 07:47 PM - Forum: Obi Softbody - Replies (1)

I'm testing with the human model.

I made two of them as ObiSoftbody into a scene and drop them from a height. I get inaccurate collision as they overlap each other.

So I go to either decrease the particle radius to 0.05 from 0.1, to make the particles generated more dense. But then the simulation drops to a crawl.

I also tried changing the overlap to 2x of default.

What am I doing wrong? The Octopus demo video has a dozen such softbody models and perform great.

I have a i7 8700 cpu

Thanks

  How to set relaxed state on first frame? (Sth. similar to prewarm?)
Posted by: fleity - 27-04-2020, 03:00 PM - Forum: Obi Rope - Replies (8)

Hey Everyone,

the team I work with recently bought obi rope and we are very happy with it however there is one thing we could not figure out at all and searching through the forum did not give us any results, maybe I am just missing the right keyword.

Is there a way to start the scene with a rope already in it's relaxed state?


Given the existing API I guess i could write this on my own, enter playmode, simulate idk 100 frames, capture current state of all particles, write them back into the blueprint or another asset and reapply all those values on start next time. 
However it seems like this kind of init / set initial state function should be so common it might already exist?


thanks for your advice
