Highlights
Core Capabilities, Up Close
01Open foundation, self-developed enhancements
Built on O3DE
DawnEngine is a closed-source commercial 3D engine built on open-source O3DE, inheriting Atom and Gems while adding large-world, AI, cloud streaming, and commercial delivery.
02Sub-mm accuracy at 100 km
Enhanced Double-Precision Rendering
Engine-wide 64-bit double-precision world coordinates: sub-millimeter vertex accuracy at 100 km from the origin, without hurting render performance.
03Seamless worlds, streamed on demand
World Streaming
Large-world streaming: automatic grid partitioning, on-demand streaming, HLOD, content layers, and multiplayer sync.
04True 3D terrain, non-destructive editing
PolyTerrain
True 3D mesh landforms with a non-destructive modifier stack, sculpt/paint tools, virtual texturing, and GIS import — natively wired to large-world streaming.
