Why MatStream
Built Different.
Built for Worlds.
Live World Media — Zero Recompile
Update ads, video streams, and any media content directly while your players are in-game. MatStream patches materials at runtime — no new build, no downtime, no visible hitches on the render thread. Run seasonal events, A/B test creatives, or change campaigns in seconds.
Any Mesh. Any Surface.
Walls, bus shelters, holograms, racing banners, NPC monitors, LED screens, city posters, decals. If it has a material slot, MatStream can stream into it. Blueprint-native, PCG-compatible, World Partition ready.
100% of Revenue is Yours.
MatStream is infrastructure middleware — the Stripe of in-game advertising. We connect your existing ad network accounts to Unreal. Your Appodeal, AdMob, or Unity Ads earnings land directly in your account. We take zero cut.
Dynamic QR Campaigns
Generate scannable QR codes at runtime inside your world. Link to apps, websites, Discord communities, events or products. Track every scan with campaign-level analytics.
Spatial Analytics
Not web impressions. Real spatial data — view time, player distance, camera dot product vs. material normal, screen occupancy percentage. Metrics that advertisers actually care about in virtual environments.

Live Content Infrastructure
Not Just Games.
Any World. Any Industry.
Unreal Engine powers more than games — architecture, film, automotive, events, training. Wherever materials render in 3D, MatStream can make them live.
LED Volume Stages.
Content That Never Stops.
Hollywood LED volumes run on Unreal Engine. MatStream streams branded content, regional adaptations, and sponsor placements directly into the stage background — between takes, mid-shoot, in real time. No re-render. No downtime. No waiting.
Walkthroughs That Close Deals.
Same virtual building. Different tenant branding per client meeting. Swap logos, signage, and interior materials live — mid-presentation.
Virtual Lots. Live Inventory.
Dealers update pricing, featured models, and promotional overlays from a web dashboard — zero Unreal knowledge required.
Simulations That Stay Current.
Safety signage, hazard labels, and procedure overlays inside virtual factories updated by supervisors without rebuilding the simulator.
Sponsor Slots. Between Sets.
Virtual concerts and events with sponsor content that swaps between acts — without touching the Unreal project.
One World. Every Language.
Same 3D environment, different material content per region, language, or user segment — streamed at runtime.
Any Unreal Engine Project. Any Industry.
