For The Callisto Protocol, Striking Distance Studios relied on InstaLOD to tackle the complexities of dense scenes, using automated material merging and LOD generation to achieve massive performance savings without sacrificing visual fidelity.

Striking Distance Studios leveraged InstaLOD as an essential tool in their development pipeline for the survival horror game, The Callisto Protocol. Facing the challenge of creating a highly detailed and immersive world while maintaining performance, InstaLOD’s automation features for LOD generation, lightmap UV creation, and material merging significantly streamlined workflows, saved countless hours, and ensured consistent optimization throughout the production cycle.

The Haunting Challenges of Production

The team aimed to craft a richly detailed world, from its terrifying enemies to its environmental storytelling. Creating the immersive world of The Callisto Protocol presented several major challenges:

• Maintaining Performance: The intricate details required careful optimization to ensure smooth performance on target platforms. Manually optimizing content for a game of this scope would have been nearly impossible.
• Time-Consuming Manual Processes: Traditional methods for generating multiple levels of detail for each asset and creating lightmap UVs were time-intensive and prone to errors, especially with assets undergoing multiple iterations.
• Managing Draw Calls in Dense Scenes: Highly detailed environments, crowds, and cinematic assets could lead to a large number of draw calls, impacting performance.

These obstacles required an innovative solution that could streamline their production pipeline while maintaining the highest quality standards to fit their vision.

InstaLOD: Scary Good Performance

Striking Distance Studios integrated InstaLOD into their Unreal Engine-based pipeline to address these challenges. InstaLOD became an essential tool, allowing the team to focus on creativity while automating crucial optimization tasks.

Key InstaLOD Features Used:

• Automatic LOD Creation: InstaLOD was configured to automatically create LODs as assets were imported into Unreal Engine. This seamless integration saved countless hours compared to manual LOD generation and ensured consistent optimization across all assets.
• Lightmap UV Generation with Overlap Prevention: InstaLOD helped generate lightmap UVs without overlaps, a common issue in highly detailed games. This also allowed for re-baking UVs directly within the engine when overlaps occurred, saving time and preventing potential lighting issues.
• Material Merge: By baking multiple textures and materials into a single texture atlas and material, InstaLOD’s Material Merge mesh operation achieved massive performance savings. This was invaluable for optimizing dense scenes, crowds, cinematic assets, and gameplay environments by reducing draw calls.

The Results: Efficiency, Resurrected

The implementation of InstaLOD provided significant benefits to Striking Distance Studios during the development of The Callisto Protocol:

• Increased Efficiency: Automation of LOD creation and lightmap UV generation saved significant time and effort, allowing artists and developers to focus on creative tasks.
• Consistent Optimization: Automated processes ensured a consistent level of optimization across all assets throughout the production cycle, even as assets went through multiple iterations.
• Improved Performance: Merged materials and effective LODs contributed to massive performance savings, crucial for delivering a smooth and immersive player experience in a highly detailed world.
• Streamlined Workflow: The ability to re-bake UVs directly within the engine using InstaLOD streamlined the workflow and prevented potential issues during lighting passes.

InstaLOD played a pivotal role in bringing the terrifying and detailed world of The Callisto Protocol to life. By automating key optimization processes, InstaLOD allowed Striking Distance Studios to maintain the highest performance standards while enabling their team to focus on creative endeavors.

“InstaLOD is one of those tools that I want to use for any future project as it allows teams to focus on creativity while maintaining the highest performance standards.” – Michael Svymbersky, Lead Character Artist
