Burst error adding component FrozenRenderSceneTag

I'm seeing the burst error:

Unable to access the managed method `object.Equals(object)` from type `Unity.Rendering.FrozenRenderSceneTag`

In a job, I'm running:

commandBuffer.AddSharedComponent<FrozenRenderSceneTag>(entityInQueryIndex, entity, frozenTag);

frozenTag is a local variable. If I add

.WithoutBurst()

to the Entities.ForEach, then it doesn't give an error.

Is this a known issue or something I'm not doing correctly?

Getting the same I was trying to use it to make a primitive render culling system but since it cant be burstable its basically useless as it takes too much time, i wonder if anyone was able to make a render culling system

 

Same here. I've been using FrozenSceneRenderTag to tag procgen RenderMesh entities as "static".

Code (CSharp):

1. var id = new uint4(1, 0, 0, 0);
2. ecb.AddSharedComponent<FrozenRenderSceneTag>(entityInQueryIndex, meshEntity, new FrozenRenderSceneTag() { SceneGUID = new Hash128 { Value = id } });
3. ecb.AddComponent<PerInstanceCullingTag>(entityInQueryIndex, meshEntity);

Code (CSharp):

1. client/Library/PackageCache/com.unity.entities@0.10.0-preview.6/Unity.Entities/Types/TypeManager.cs(627,17): Burst error BC1001: Unable to access the managed method `object.Equals(object)` from type `Unity.Rendering.FrozenRenderSceneTag`

Hybrid Renderer 0.5.0-preview6 and entities 0.10.0-preview.6.

 

Does that mean we can expect a future Entities package update will change this as you suggest, and in the meantime, we should use .WithoutBurst() for the jobs using AddSharedComponent? Thank you.

 

Running in this issue as well. A fix would be nice.

 

Given I just ran into this same bug month later, I'm guessing it's still not fixed?

 

i'm also encountering this issue

 

Same issue here in 0.16

 

Has a fix been merged?
