This is my mother in 3D.
Rendered with the NVIDIA NvRTX Unreal Engine 5.4 branch from GitHub.
Using Ray Traced Sampled Direct Lighting (RTXDI) and ReSTIR GI, I noticed a better, cleaner and more stable Global Illumination (GI).
I got more detailed skin with Path Tracer, but some weird parts.
So I did two EXR renders and composed some parts of each to achieve a better look.
Render 1: ReSTIR GI with RTXDI
Render 2: Path Tracer with 300 samples.
Process:
- Scanned with Polycam and then converted to a Metahuman.
- Used Blender with KeenTools FaceBuilder plugin to create 8k texture compatible with Metahuman.
- Edited the texture in Adobe Photoshop and then created a normal map.
- Processed the texture in Beeble SwitchLight Studio, so AI removed some reflections/specular and created a better albedo map.
- Rendered in UE 5.4 NVIDIA branch (as mentioned above).
- Composed both renders in Photoshop.
- Color grading and AI filter for smoothing the hair in Lightroom.
That’s it. Hope you like it.
