Eight years after release, Dark Souls modders figure out how to make custom maps.

It might be surprising, but until this point it's been pretty much impossible to import a custom map into the original Dark Souls. According to Souls modders, the closest you could get was importing maps from Demon's Souls - and while modders have worked on custom maps for some time, problems with the specific file format used for collision detection in Dark Souls 1 meant that progress was stalled.

Until now, that is, as several modders have figured out a way to import working custom maps into the game.

As explained by modder Zullie, progress began in earnest when modder Meowmaritus created a tool to import models, but without collision detection (in layman's terms, the physics required to make things actually solid). The next step was carried out by modder Horkrux, who recently developed a way to create collision maps.

Why was it so hard to get to this point? As modder Katalash explained on Reddit, all Dark Souls games use the proprietary (essentially secret) file format Havok to store collision data, with FromSoftware adding their own customisations on top. "To further complicate matters, the file format and stored data change drastically between game to game," Katalash added. But Horkrux figured out that using an old version of Havok Content Tools (that were released publicly for only a short window of time before Havok stopped distributing them) would allow them to create collision maps in Dark Souls 1, Dark Souls: Prepare to Die Edition and Dark Souls 2.

"Simply put, we were apparently way overthinking it," Zullie told me over Discord.

"We had initially thought we'd have to reverse engineer the collision format that Dark Souls uses in order to be able to generate custom collision, but Horkrux figured out how to do it just by using official Havok tools. It turns out FromSoftware didn't make anything especially fancy, Horkrux just needed to make a template for Havok."

While this is a significant breakthrough for the Dark Souls modding community, both Katalash and Zullie believe there's still a long way to go before importing custom maps becomes an easy process.

"The Souls modding community is lacking any sort of formal support, but more than makes up for it in passion," Zullie said. "A few years ago it was a Herculean effort to just put a new model for a weapon into the game. We're continually picking the game apart and then developing the tools to streamline it."

"However, I don't imagine anyone's likely to make an automated process for this while navmeshes remain an obstacle, since the practical applications would be pretty scarce," she added. (Navigation meshes are necessary to help NPCs and enemies pathfind around a map - and like collision data, navmesh data varies wildly between the Souls games.)

"Without them, the best we can essentially make would be strictly PvP focused arenas. With them, we could create entirely new, fully functional levels for the game - player published DLC, for all intents."

Great job, modders. Sounds like navmeshes are still an obstacle, but with any luck this will bring additional interest into figuring out the rest.
