(ECS+LWRP) Meshes disappear on camera position/rotation change

Hi,
Can somebody guess what may be happening here? Gif below presents the problem (watch yellow spheres):

Meshes disappear and show up again in specific camera angles or positions.
Also removing some entities while program is running makes some some of them appear again. It happens in non random but linear/chronological order of their creation I think.

Im using hybrid ECS+LWRP here. These spheres are using LW/Lit shader (GPU instancing enabled but disabling it changed nothing). What's interesting this is not happening when I change their material to built in "SpatialMappingWireframe"

Any thoughts or pointers on this?

 

May be a side effect of the new SubScene+Conversion workflow. If you are using preview 26 or later, does reverting back to entities preview24 fix your issue?

 

That would be really strange since I don't have any SubScene here nor use any Conversion utility yet.
Unfortunately to know 100% I can't easily revert to p24 because my codebase breaks down under this version

 

Yeah, you may not need to actively use SubScenes to experience side effects inside of SubSceneLiveLinkSystem. Again, I'm not 100% sure it's the case. But you can try to filter it out to test if it helps.

Code (CSharp):

1. public class CustomBootstrap : ICustomBootstrap
2. {
3.     public List<Type> Initialize(List<Type> systems)
4.     {
5.         return systems.Where((t) => t.Name != "SubSceneLiveLinkSystem").ToList();
6.     }
7. }

@andrew-lukasik did yu fix it...?

I am experiencing a similar problem in a very similar scene condition. Let me know, please. Thanks

 

Hi @surits14 . I honestly don't know. It fixed itself somewhere between new Unity versions OR I fixed it somehow without realizing when/how exactly.
If you're using older ECS code then make sure it's more up to date ie.: You're using IConvertGameObjectToEntity workflows, latest entity packages etc.
