Pearl Abyss says it chose its own Blackspace Engine for Crimson Desert because the studio wanted direct control over development rather than depending on a commercial engine such as Unreal Engine 5.
Developers from the Korean studio explained that using an external engine could have slowed the game's production and post launch updates if the team had to wait for new features or technical support.
That flexibility became particularly important after release, when Crimson Desert received a steady stream of patches and feature updates.
Blackspace was built to avoid outside dependencies
Pearl Abyss already had experience creating its own technology through Black Desert, so moving to a third party engine for Crimson Desert would have represented a major change in development philosophy.
The team acknowledged that commercial engines offer strong tools and practical features, but said it did not want to rely on external technology for core areas of game development.
The developers also suggested that their internal workflow may not have matched the update cycle of a commercial engine.
If an important feature required an engine update, the studio could have been forced to wait before implementing it.
| Area | Blackspace Engine approach |
|---|---|
| Engine ownership | Developed internally |
| Main goal | Greater technical and production control |
| External dependency | Reduced |
| Update flexibility | Features can be developed directly by the studio |
| Platform support | Designed for multiple platforms |
| Genre flexibility | Built to support games beyond one genre |
| Future potential | Could support FPS, TPS and other projects |
That control was one of the main reasons Pearl Abyss continued investing in its own technology instead of adopting Unreal Engine 5.
Black Desert's engine had become too specialized
The decision was also influenced by lessons learned from Black Desert.
Its engine was built heavily around the needs of that specific MMO.
Over time, that specialization reduced its flexibility and made it more difficult to use for games belonging to other genres.
Blackspace was designed differently from the beginning.
Pearl Abyss wanted the newer engine to support several types of game worlds and work across multiple platforms without requiring the studio to rebuild its technology for every new project.
The developers said the engine is not perfect, but they see no reason to replace it completely.
They also believe the same technology could potentially support other types of games, including first person and third person shooters.
Crimson Desert updates show the value of direct control
Crimson Desert has received several major patches since launch, including visual improvements and broader changes to the game.
The studio argues that owning the engine helped it deliver those updates more quickly.
Instead of waiting for an external engine developer to add a feature or solve a technical problem, Pearl Abyss can modify the underlying technology directly.
That does not automatically make a proprietary engine better than Unreal Engine 5.
Commercial engines provide mature tools, documentation and large developer communities that can reduce development time in other areas.
Pearl Abyss simply chose a different tradeoff.
For the studio, direct access to every part of the engine was considered more important than the convenience of adopting widely used middleware.
The engine is intended for more than one game
Blackspace appears to be a longer term investment rather than technology built only for Crimson Desert.
The studio specifically designed it to avoid the limitation it encountered with the Black Desert engine.
If Pearl Abyss successfully reuses Blackspace across different projects, the cost and effort of developing a proprietary engine could become easier to justify.
The company believes the technology can support a range of genres while maintaining consistent tools across different platforms.
That could also allow future games to benefit from improvements originally created for Crimson Desert.
Pearl Abyss's approach stands out at a time when many large developers have moved toward Unreal Engine 5.
Rather than following that trend, the studio is betting that control over its technology will give it more freedom to develop, update and expand its games on its own schedule.
For Crimson Desert, that decision has already shaped how quickly new features and technical improvements can be introduced, while Blackspace is now being positioned as the foundation for projects beyond the game itself.
