There is no overload for method 'Graphics.DrawMeshInstanced' that takes NativeArray<Matrix4x4>

If the overload existed, there shouldn't be any unnecessary allocations and I could write programs as below.

unsafe

{

    using(var renderMatrices = new NativeArray<Matrix4x4>(114514, Allocator.Temp))

    {

        InitializeArray(renderMatrices);

        var renderMatrixPtr = (Matrix4x4*)NativeArrayUnsafeUtility.GetUnsafeReadOnlyPtr(renderMatrices);

        for(int consumed = 0; consumed != renderMatrices.Length;)

        {

            int tryToConsume = Math.Min(1023, renderMatrices.Length - consumed);

            var tryToConsumeArray = NativeArrayUnsafeUtility.ConvertExistingDataToNativeArray((void*)(renderMatrixPtr + consumed), tryToConsume, Allocator.None);

#if ENABLE_UNITY_COLLECTIONS_CHECKS

            NativeArrayUnsafeUtility.SetAtomicSafetyHandle(ref tryToConsumeArray,  AtomicSafetyHandle.GetTempUnsafePtrSliceHandle());

#endif

            Graphics.DrawMeshInstanced(mesh, subMeshIndex, material, tryToConsumeArray, properties, castShadows, receiveShadows, layer, camera, lightProbeUsag, lightProbeProxyVolume);

            consumed += tryToConsume;

        }

    }

}

There is no allocation.
I hope the Unity Team to implement this overload as soon as possible.

 

Thank you for replying.
I am very happy to hear what you said.

 

Is it possible Graphics.DrawMeshInstanced would also be available to call from inside a job in the future?
