I´m unable to reproduce this problem. Installed Obi Rope 7.0.3 on Unity 6, works without issue.

The error message you shared points to the following line:

Code:

GameObject.Instantiate(Resources.Load<ComputeShader>("Compute/Solver"));

A null reference here means the /Obi/Resources folder has either been removed after installing the asset, or the asset has been improperly installed. Please follow the setup guide, and don't delete any asset folders/files after completing installation as doing so will prevent the asset from working properly - or at all.

kind regards,

Thank you for responding.
I followed the setup guide and installed Obi Rope in a fresh Unity 6 LTS project without making any changes, but I encountered the same error. Interestingly, when I try the sample scenes, the errors disappear, and the asset works as expected.

I tried importing Obi Rope by skipping dependencies and got the same error.

If running a scene does not trigger the issue, would you mind specifying when does it happen? Is it immediately upon importing the asset, even without running it?


This issue has nothing to do with dependency packages. The cause of the problem is that the asset is trying to load a compute shader (normally located in Obi/Resources/Compute/) but is unable to find it. That’s why I assumed either the folder or its contents had been removed or improperly imported during installation. Note this would only happen when using the compute (GPU) backend, since the default backend (Burst-CPU) does not use compute shaders.

Kind regards,
