AssetCompiler is unable to resolve material references from layers of materials

[laske185]

Release Type: Official Release

Version: 4.1.0.1734

Platform(s): Windows

Describe the bug The asset compiler throws an exception when a material uses in a layer another material that is already used f.e. by a model. The issue is non-deterministic an depends on the order the references are handled in one run.

To Reproduce Steps to reproduce the behavior:

1. Create a scene with the following setup:

flowchart TD
  subgraph Entity
    ModelComponent
    SomeComponent[Some component with a reference to a material]
  end
  subgraph MaterialB[Material B]
    Layer[Layer 1]
  end
  ModelComponent --> Model  --> MaterialA[Material A]
  SomeComponent--> MaterialB --> Layer --> MaterialA

2. The asset compiler compiles successfully when material A is visited via the model first, but failes when it is visited through material B the first time.

Expected behavior The asset compiler always handles the referenced materials in layers of materials correctly.

This is simple project using material archetypes. It cause same error as above, but only at specific HDD location. When it is coppied to another location it builds fine. Is it possible that this can affect the order of the asset compilation? For example, in what order are the files returned from disk and in what order does compilation occur? So it's very likely that you won't get the error... But this simple project cause problem at least in my case...

[laske185]

The behavior always occurs. But it can succeed when the previous build already compiled the assets. It can always be reproduced when the data folder in the bin folder is removed. F.e. .\Bin\Windows\Debug\win-x64\data.

I created a sample project to reproduce the error: https://github.com/laske185/stride3d-sample-MaterialAssetCompilersBuildDependency
