I was looking for some tools that can create procedurally created terrain. I want to have some assets such as tents to be recreated after they are destroyed and maybe make some grass. I wanted to make sure I was using the best assets out there. Also, I need a pre-created asset for the blowing of the wind unless some tools can do this too. I thought about gaia but want to know people opinions to this. I prefer tools that follow the simple to pickup and learn model versus easy to use (easy to use means their might be a higher learning curve involved).
