Hello @Drogoberto
Welcome to the forums! Thank you for your application.
The title of this post states that you want to work in "3D Environment and Props" do you have any suggestions on the existing objects in the game ? If not is there anything in particular you'd like to work with (e.g. trees, rocks, building scaffoldings, foundations...)
Are you familiar with versionning and compilation ? If not that's fine, but it's better if you manage to use the Mac Dev Version. On Windows we provide binaries.
