In legacy ROBLOX games, I believe ROBLOX used the GPU volume buffer to create a technique that basically had infinite resolution sun shadows, they removed this when adding dynamic lighting because that technique simply does not work well alongside dynamic lights. When trying to recreate old ROBLOX lighting to the best of my ability with the modern, heavily restricted tools, the first thing I thought of doing was increasing the shadowmap resolution, but that isn’t really an option from what I can see, can anybody help out with this?

Yeah, I wouldn’t say its trash in terms of dynamic lighting, but in cases where dynamic lighting isn’t needed, I would much prefer to reach something somewhat close to the classic shadow style, closest I’ve gotten with shadowmap is making the shadows incredibly sharp, but the low shadowmap resolution causes issues when trying to get that lossless look of old roblox shadows.

For me, I think ROBLOX changed it somewhere in the game files, it came out at 2019 I think.

Fairly certain dynamic lighting was 2015 ish, and yeah its def something in the files, but I’m talking about achieving a similar look with what we have today.

Hi, again i manage to get a script to change all of this.

The script, in lightning and make a bloom called NoBloom then make the size 24 - ThresHold 0.95 and the rest 0

I mean its nice lighting but it honestly doesn’t really fix the shadow at all, it’s still very soft, and if you set softness to 0 it looks incredibly low-res and pixelated.
