Bug Burst fails to compile GLTFast

 

[BurstCompile, MonoPInvokeCallback(typeof(GetIndexDelegate))] 

static int GetIndexValueUInt8(void* baseAddress, int index) 

{ return *((byte*)baseAddress + index); }

The method in question, Int32 GetIndexValueUInt8(Void*, Int32), is a function pointer defined within the GLTFast package, specifically within its Jobs functionality. Burst is unable to compile this method, which is causing the thrown exception.

Burst version: 1.8.2
GLTFast version: 5.0.0 or 5.0.4 (all encountered the same problem)

 

Also I am wondering how to downgrade the version to Burst 1.6.6, I tried with changing manifest.json and packages-lock.json, but the version of Burst downloaded was still 1.8.2. I am using MacOS with M1 Pro chip if this information could be of some help.

Look forward to reply! Thanks!

 

Additional information: Unity environment is 2021.3.16f1, and cannot be upgraded due to some package limitation. Thanks!

2. the package manager looks like this:
I am wondering if it is because I am using 2021.3.16f1 that I am unable to upgrade Burst.
So I am wondering if there is any chance to downgrade to Burst 1.6.6, if so, how to do that except changing packages-lock.json and manifest.json.




Many thanks ahead!!!!!!
