Since VR is uncharted territory, we had to spend many many months experimenting and finding the best way of working. Despite trawling the internet for development guides, there was very little advice out there. We spent a lot of time sympathising with other VR devs online and sharing our findings with the community. No one really had a clue how anything worked.
Our first try at building a game map was an absolute disaster, albeit a lot of fun! To begin with, we tried to build an entire continent directly in UE4. The below is roughly based on London and the River Thames and was intended to just plot out the main areas so we could get an idea of scale.
Then we found the terrain tools in UE4 and built a pretty landscape.
We then tried adding a few objects to make it more interesting.
Until we finally reached the point where UE4 was so laggy that it was impossible to add any more content. At that point we realised we would need to find an alternative method.
It was another two weeks before one of our team happened to meet someone online that had used some amazing software called World Creator. Suddenly, our mapping problems were solved!
