Async load scenes that has Obi rope, crash?

[lacasrac]

Obi rope worked like a charm in my big scene.
Finally I decided to break up my big scene into small ones. (a script cut my big scene into small ones)
After this I just call Async load/unload that scenes. And my probleme is:

++ LoadSceneSectorAsyncCoroutine _SCENE_SECTOR_Factory ...
Crash!!!

in that SCENE I have an Obi rope.

System.IndexOutOfRangeException: Index {0} is out of range of '{1}' Length.

Can you help me what is wrong? Did you tried with a scene that has an Obi rope with AsyncLoad?

Thanks,
Leslie

Hi there,

Just tried loading a scene asynchronously, but wasn't able to reproduce this. Which Unity and Obi versions are you using?

Where can I find the version number?

The bigger probleme is that the rope is moving left from right very fast in AsyncLoad and after some seconds calm down

In my big scene I don1t I experienced this behaviour

Same as with all assets: In your asset store account, or the package manager. You can also it in the Obi/CHANGELOG_rope.txt file, it's the version at the top of the file.

If your rope is attached to colliders/rigidbodies, make sure these are part of the same scene. If you load them separately, the rope will have no object to attach to and behavior of the simulation will be different.

Other than that, I can't think of a reason why the rope would behave differently depending on how you load the scene. If the issue persists, I'd have to take a closer look at the project to figure out what could be the culprit. In this case you can send the project (or a stripped down version of it) to support(at)virtualmethodstudio.com and I'll take a look at it.

kind regards
