Hi there!
As stated in the store description and the manual, Obi requires Burst, Jobs, Mathematics, and Collections to work. If it doesn't find them installed it will attempt to fall back to a native-library based backend, which only has support for Windows, Linux and Intel Macs. In particular, it doesn't support the Apple Silicon architecture so if you're using it you'll encounter the libOni.dll not found exception.
Make sure your ObiSolver components do not have the following warning in them:
![[Image: burst_warning.png]](http://obi.virtualmethodstudio.com/manual/images/backends/burst_warning.png)
If they do, that means some package is missing or uses an older version than supported. Please refer to the manual for a list of minimum versions for each package.
Some versions of Collections use length and some use Length with a capital L, Unity's auto API updater should take care of this. Changing it manually is also possible.
Some of the sample scenes contain a ObiProfiler component, that will only work when using the fallback system. In your case you should remove this component since the fallback isn't supported at all in your architecture.
Not all of the included sample materials have URP equivalents, so Unity may fail to automatically convert them:

The VertexColor one is just the built-in's pipeline Standard shader with added vertex color support. Any URP material with vertex color support can be used instead of it. Note this is not necessary for the asset to work, since rendering and simulation are completely orthogonal to each other.
kind regards,

Quote:Unity may fail to convert all materials in a scene, in that case you can just select the remaining pink objects and change their material/shader to an URP/HDRP compatible one.
The VertexColor one is just the built-in's pipeline Standard shader with added vertex color support. Any URP material with vertex color support can be used instead of it. Note this is not necessary for the asset to work, since rendering and simulation are completely orthogonal to each other.
