Compiltation fail DefaultMaterial

Dear everyone,

We are searching for help on an issue that recently appear with our project:

We are trying the new feature Material Substrat and since then we are facing issue like this one:

UATHelper: Cooking (Windows): LogShaderCompilers: Warning: Failed to compile Material /Game/Glyphen/Landscape/Materials/M_Landscape_CaveFloor.M_Landscape_CaveFloor (MI:/Game/Glyphen/Maps/Glyphen.Glyphen:PersistentLevel.LandscapeStreamingProxy_0UWC8TZGAKW5PWD34729LSTSK_252_3_0_0.LandscapeMaterialInstanceConstant_9) for platform PCD3D_SM5, Default Material will be used in game.

And finally, the cooking fails with this error:
