The archive contains 3Ds Max 2020+Corona9 files, FBX file and textures.

Some objects in the file are made under Turbosmooth. The Turbosmooth stack is disabled in the New Decor Set_2020.max file.
You can adjust the model for smoothing yourself by changing the iteration value.

PS For Corona render, it is recommended to install version no lower than 1.5, since the glossiness of materials is configured taking into account PBR.
Beautiful renders to all!
