With the release of Unreal Engine 5 (UE5 for short), game developers and digital artists have a new opportunity to create more realistic and stunning games and virtual environments under its powerful rendering engine. Scenes. However, to achieve excellent realistic effects, you need to set up the project properly and use some skills and strategies. This article on 3DCAT real-time rendering will explore how to improve the realistic effects of UE5 through project settings, bringing a better visual experience to your works.
The following project settings can improve the picture processing effect of UE5 and can be set according to needs.
1. Project settings need to turn on ray tracing
2. Check the transparent layer to enable the second normal, check to enable virtual texture support, and work in the color space SRGB/REC709.
3. In windows, find the default RHI and open DirectX 12.
4. In the rendering, find global illumination and reflection, and turn on lumen.
5. In rendering, open the reflection capture resolution in reflection and set it to 1024.
6. In rendering, open the following settings, use hardware ray tracing, change the detail tracking of software ray tracing mode, check to support hardware ray tracing and ray tracing shadows, and check to generate mesh distance fields.
7. Turn on rendering and turn off automatic exposure to easily control lighting effects.
8. Open the GBuffer format and switch to high-precision normals
9. Turn on visual effects and create post-processing volumes.
10. Post-processing volume settings
11. In UE5, Lumen replaces the traditional SSGI in UE4. When setting up the Lumen project, the Ambient Occlusion in PostProcessVolume has become invalid.
Write r.Lumen.DiffuseIndirect.SSAO 1 and r.Lumen.ScreenProbeGather.ScreenSpaceBentNormal 0 on the command line
At this time, SSAO has taken effect, and the intensity and radius of AO can be controlled in postprocessVolume;
After checking, the AO effect will take effect.
r.Lumen.DiffuseIndirect.SSAO 1
r.Lumen.ScreenProbeGather.ScreenSpaceBentNormal 0 （UE5.1版本）
r.Lumen.DiffuseIndirect.SSAO 1
r.Lumen.ScreenProbeGather.ShortRangeAO 0 (UE5.2 version)
We can see that SSAO is in effect in the ambient occlusion view, and can use PPV settings to adjust its intensity and range. The SSAO and Lumen AO here are superimposed.
As mentioned above, with proper project setup and the application of some tips and strategies, you can improve the realism of UE5, so go give it a try!
