PBR Support

Lyrae supports LabPBR standard. So make sure to use a resourcepack with LabPBR material support, here's a LabPBR on shaderlabs site.

Performance Tips

- I tried to write detailed descriptions for all settings, so you can hover over them in-game for more detailed performance tips. - `Samples` is one setting with the most impact on the performance, because it increases the path complexity exponentially. Try to keep this at 1 if you want to enjoy real-time. - You can try changing the `Resolution Scale` setting, lowering this from 100% will make the lighting quality lower. - For most scenarios 3 bounces is enough. 2 bounces will not have indirect lighting, so GI will look less accurate. - If you are in a *completely isolated* room where no sunlight is visible, you can try disabling NEE. Note that disabling NEE will break sun light. - You generally shouldn't mess with SVGF settings unless you know what you're doing. If you are okay with noisy image you can disable spatial filtering.
