Hey everyone, welcome to my madness! So I’ve been working on a game like Minecraft for a long time with one of its key characteristics being that it has more modern graphics. Aiyana: x.com What I’ve struggled with from early on is how the hell am I going to support player placed lights? Well the …

Not my forte, but since nobody else has answered and I had the link, you could look at segi to get a better picture of a full voxel solution: [image] GitHub - sonicether/SEGI: A fully-dynamic voxel-based global illumination... A fully-dynamic voxel-based global illumination system…

Thanks for the responses but I don’t think/know if these will solve my issues :frowning: From what I’ve read about SSGI I’m guessing it doesn’t affect the shadow generation. E.G when reading on the HDRP docs: “SSGI and RTGI completely replace all lightmap and Light Probe data.” but nothing about i…

GI is just a nice to have that I’m not worried about, yet. Overal yes I want to optimise shadow performance but ideally I’m trying to find out if there are systems where I can support as many shadows as possible without nasty hacks, since players can place as many lights as they like in the world. …

And render shadows onDemand, maybe a good value would be twice every second, instead of how it is now, 60(assuming your FPS is 60) times per second. Unfortunately as it is, point light shadows have huge performance costs, more than usual i’d s…

[image] LaireonGames: Isn’t this all HDRP only? I don’t think I can hack the conversion to HDRP yet, its a complete rethink of so many important aspects of the project and I highly doubt I can recreate our current visual style of volumetric lighting. Agreed, its obscene how much CPU time it tak…

[image] PutridEx: Oh my bad, my mind instantly thought you were using HDRP when you mentioned modern graphics. :smile: Cool project by the way! This is the sad state of Unity right now, HDRP really should be the perfect fit for this project but I just have zero confidence that what Unity say…
