Haha… I wondered how long it would take for threads like these to pop up, Aside from the ‘Make Game’ button - the reality is DICE put a lot of hard work into it. A few things I know:
- All terrain textures are generated through Photogrammetry. And I’m talking the ‘proper’ photogrammetry with loads of camera filters to get the right maps, displacement-mapping rig and scanning software etc.
- While World-Machine is possibly a good contender for generating the actual topography and global maps, honestly I wouldn’t be surprised if DICE / EA have their own in-house tool for things like this because more often than not they do. I know a tools programmer from EA, that guy works bloody hard.
- They also traveled to the film locations and took photographs, did a lot of real-life reconnaissance of the areas they were recreating.
My advice would be to get a full copy of World Machine and follow heaps of tutorials. The terrain on Marketplace that you linked is nothing you can’t do without going through some World Machine tutes, so save yourself the cash and learn how to do it yourself - you’ll benefit from it in the long run.
