I am at the VERY beginning of my journey to try and create a world that I and others can immerse in for hours, days, and even longer. I am researching what programs I should learn to achieve certain tasks. My initial task will be to create the physical world I want to populate with AI animals etc. What programs with an easier to grasp interface are out there that are very good at rendering architecture that can be traveled within.
For example if I wanted to create some ancient middle eastern inspired architecture that people can explore what programs works best for creation and have an easier interface with Unreal Engine 4?
I appreciate your time and look forward to your responses.
