Expected roadmap
Planned Features
The following feature tracks represent larger ProStream capabilities that already exist as meaningful prototypes, advanced subsystems, or modules waiting for integration. They will expand ProStream into a broader world-building and streaming toolchain.
What this section means
These pages document feature areas that are either already partially implemented, archived while being refactored, or planned to return as product-facing ProStream capabilities. They are useful for evaluating the direction and technical depth of the asset, but they should not be read as promises of immediate shipping scope.
There is no current timeline or guarantee that these features will be released and included in ProStream unless explicitly stated.
Why these features matter
Build/Runtime reductions
DataObjects reduce memory usage and build size. Resulting in compact, data-only GameObject representations to drastically reduce MonoBehaviour overhead.
Terrain-native streaming
Terrain generation, mesh conversion, and detail streaming outline a path for bringing Unity Terrain into the same streaming-first architecture as the rest of the package.
Smarter rendering systems
Visibility culling and impostor baking show how ProStream can expand from scene preparation into runtime visibility and long-range rendering optimization.
Feature Summary
| Feature | Status | Description | Why it matters |
|---|---|---|---|
| Visibility and frustum culling | Beta subsystem | Extracts camera frustum planes and applies section-level visibility culling so streamed terrain and scene sections can react to what the camera can actually see. | Can provide a significant increase in runtime efficiency by intelligently unloading dense environments when they move off-screen. |
| DataObjects workflow | Advanced prototype | Produces compact, data-only GameObject representations, then spawns streamed entity instances from section buffers instead of copying every full GameObject into generated subscenes. | Reduces runtime overhead, minimizes duplication, and actively shrinks build sizes and memory footprint. |
| RemoteScenes workflow | Advanced prototype | Splits preparation work across referenced scenes so complex environments can be processed in smaller scene units without leaving the core ProStream workflow pipeline. | Eases Editor memory pressure and speeds up iteration when working with dense, heavily populated environments. |
| Terrain System | Substantial prototype | A comprehensive pipeline for chunking and rendering Unity Terrain environments into highly optimized, streaming-friendly ECS content. | Replaces memory-heavy monolithic Unity Terrain, automating scanning, mesh conversion, and proximity detail streaming to maximize runtime performance. |
| Impostor baking | WIP module | Bakes complex meshes into multi-frame impostor atlases and materials for aggressive long-range rendering optimization. | Vastly improves long-distance optimization for foliage, structures, and complex world geometry without high polygon counts. |
