LogMaterial: Warning: MyProjectPathHere\Plugins\ImpostorBaker\Content\ImpostorBaker\Materials\Debug\M_VSShrink.uasset: Failed to compile Material for platform PCD3D_SM5, Default Material will be used in game.

Okay, so first requirements are:

• Unreal Engine 4.19
• Blutility plugin: in Editor Preferences -> General -> Expermiental -> Tools -> Editor Utility Blueprints (Blutility)
• BlueprintMaterialTextureNodes plugin: in Plugins -> Build-In -> Blueprint Material and Texture Nodes

Then there is only a warning for the following missing texture:
/ImpostorBaker/ImpostorBaker/Textures/RT_512
