Unreal Engine 4.6 NVIDIA VXGI Shows Breathtaking Visuals
NVIDIA has recently introduced its new Dynamic GI called VXGI. VXGI has been integrated in a separate branch of Unreal Engine 4, and 3D artist "Byzantos" shared his results after experimenting with the new solution.
Byzantos claims that NVIDIA VXGI is the most accurate solution available today. you can view some screenshots of his work, in the gallery below:
Byzantos' notes regarding Nvidia's VXGI:
So what gives? Is this relatively new dynamic GI method worth giving a closer look? I reckon it is! Currently the most accurate solution available. Nothing else comes close if you’re talking about quality versus performance. Even though still a beta, it already impresses with really good colorbleed, AO and its single light bounce. Add to that NVIDIA is looking into integrating a second bounce whilst improving the output and you’ve got a really strong contender for dynamic GI in games and maybe even Arch-Viz.
- Accurate ColorBleed from Diffuse
- Ambient Occlusion (as opposed to Screen Space Ambient Occlusion)
- Stunning GI from Emissive materials
- Specular tracing offers an interesting alternative to SSR
- Looks fairly good on low-settings/low-performance impact
- Can look incredible on high/extreme settings
- Excellent tweak and management controls
- Fairly good range before quality degrades
- Requires recompile of Master-Materials for Voxelization
- Recompiling Master-Materials takes longer than acceptable.
- Terrible stability when scene includes animated assets.
- Prone to small lighting errors even on fully static scenes.
- No GI from particles.
- Does not support all Material types.
- Specular tracing yields rather low resolution for reflections.
- Small objects still need SSAO and SSR or will ‘float’.
- Can be tricky to tweak for scene-specific circumstances.
- Separate Unreal Branch, lagging behind core developments.
- Slim chance of ever getting integrated into main branch.
In short: Promising.
When it works it looks really good.
It does however come with a few strings attached so to call this production-ready
is simply too soon. I’ll be keeping my eyes on this one for sure!
Nvidia's GI solution appears to be quite amazing, and its implementation in the Unreal Engine 4 is definitely great news. Lets hope that we get to see the solution implemented in games pretty soon. We will bring you any new information on Unreal Engine 4 and NVIDIA's VXGI, as soon as it becomes available. You van check out our previous Unreal Engine 4 coverage for more, here and here.
