// 1) Thread A creates the new ShaderAsset, loads it, and gets the old ShaderVariantAsset.
// 2) Thread B creates the new ShaderVariantAsset, loads it, and calls OnAssetReloaded.
// 3) Main thread calls ShaderAsset::PostLoadInit which connects to the AssetBus but it's too late to receive OnAssetReloaded,
// so it continues using the old ShaderVariantAsset instead of the new one.
// The OnAssetReady bus function is called automatically whenever a connection to AssetBus is made, so listening to this gives
// us the opportunity to assign the appropriate ShaderVariantAsset.
