Help About the cloth generation script before execution

[tukuyo]

I'm trying to generate multiple fabrics using Obi.
I created it by referring to SackGenerator, RuntimeClothGenerator, etc., but there is a problem because initialization is not executed.

I want to execute initialization. what should I do?

I know how to generate it during execution, but how can I run it in an editor script before execution?

Hi,

I'd need to see what your current code is to be able to tell what's wrong.

Thank you for your quick reply.

The script is attached below.

The first is the Editor script.

The second is the part of the script that is run from the Editor script.

The third is a script attached to the generated Cloth object.

(In some places, comment out and Japanese is written, but don't worry.)

Hi.

cloth.GeneratePhysicRepresentationForMesh is a coroutine, and CoroutineJob() is meant to execute coroutines in the editor. Use StartCoroutine instead. See:
https://docs.unity3d.com/ScriptReference...utine.html

Thank you for your polite explanation and quick reply.

I would like to use StartCoroutine.
Thank you very much.
