Cannot encode mesh in latest version.

Tried exporting both a GameObject (default sphere) using Tools > Draco > Encode Selected GameObject and received this error:

InvalidOperationException: The NativeArray can not be Disposed because it was not allocated with a valid allocator.

Also received this error sporadically afterwards:

A Native Collection has not been disposed, resulting in a memory leak. Enable Full StackTraces to get more details.

Same error appeared both when installed using Install-com.atteneder.draco-2.0.0-preview.unitypackage as well as pulling the latest source from github.

I couldn’t reproduce on 2020.3 LTS nor 2021.1. It makes no sense to me to spend time fixing it for 2020.1, so please upgrade to 2020.3 LTS and see if this solves your problem (reopen and provide steps to reproduce otherwise).

Thanks!

Can i ask you something? @sam598 How did you build dracoenc_unity,dll? I can’t find that dll file in draco unity I got Error at [DllImport(“dracoenc_unity”)] I got same issue A Native Collection has not been disposed, resulting in a memory leak. Enable Full StackTraces to get more details.

You shouldn’t need to build the binaries yourself. This project uses GIT LFS for dll files, so please make sure you have GIT LFS installed when cloning this repository. Otherwise, the binaries are built in this GitHub project’s actions.
