This demo showcased the possibility of using 5G network for an AR experience. The demo was to show the real-time lighting changes on a realistic human character on a mobile device.

I was in charge of optimizing the 3D scanned model that we purchased. I reduced the poly counts of the model and created all the additional maps for the materials in our proprietary game engine that the vendor did not provide. I also made hair and facial hair geometries and textures.

The demo was shown at the Mobile World Congress America 2018.

Asset Showcase Video From Marmoset Toolbag

The showcase video above closely depicts how the character was rendered in the proprietary engine. The video above was made in Marmoset Toolbag using the real-time ray tracing rendering mode.

We purchased two separate assets, one for the female head and one for the firefighter suit. I worked on re-scaling, adjusting, and optimizing the models to blend into one cohesive model. Both assets also did not come with any game-engine-appropriate textures. So I used the base color texture to create all the additional maps and added the dirt effects to make the character looks like she had just finished her mission.

The asset did not come with any hair model, so I made the card-based hairstyle, eyebrows, and eyelashes from scratch.

Preview images above were taken in Unreal Engine for personal portfolio purpose. The actual demo was done using proprietary game engine, but is not available to share.

Model Update Breakdown

Updated head model/texture

I reduced the polycount of the model and re-adjusted the position so the rigging artist could rig the model in an optimal pose. I also updated the overall head textures. I also added PBR textures and proprietary engine-compatible subsurface scattering and hair textures since the original model didn’t have game-engine-compatible PBR textures.

The dirt marks on the face were a non-destructive layer I added using Substance Painter.

Original Purchased Model

This was the original head scan model we purchased for the demo.

Updated firefighter suit/body model and texture

We purchased separate firefighter assets for the body and merged the two models. I adjusted the proportion, updated the textures, and added PBR textures since the original model didn’t come with game-engine-compatible PBR textures.
