Thanks maru, yes, I am aware of cleanliness in the scene, and the potential of how it could look like subsiding plaster, etc., but mostly the purity of the intent of this project. It's a commemorative picture on the existing cottage, which is in the state that you would like to see some render, but my girlfriend would not appreciate it :D
Parallel doing another project where I would like to use the maximum possibilities of Corona and the best result :)
