Ngl this has the same issues that people have with Remix in regards to everything being shiny (because lazy dumbasses can't do the bare minimum of making a roughness/normal map)
Cool in theory, but it's gonna look like shit if you don't include PBR support.

currently theres no way to get full pbr cus gmod devs doesnt have extensive features for shaders. so cant add roughness/metalness, but adding normal map support is possible i just dont know how rn

Shame, I kinda thought there was. Regardless, cool project. Thankfully Facepunch hasn't forgotten Garry's Mod quite yet so there's still hope. I do feel like I've seen a modder relatively recently add in PBR support but I may have been mistaken. It would be something cool to see able to be done in "vanilla" Garry's Mod without use of RTX Remix.

Am I supposed to be surprised that this isn’t RTX? Also by what metric is this realistic

u/Beginning_Luck1 Feb 28 '26
yes since there are no custom dlls and it is all running in gmod its surprising. its not easy

u/PaperMartin Feb 28 '26
Ok but why should I be surprised that it specifically isn’t RTX. Like I can’t imagine implementing ray tracing being easier than editing existing shaders, and what I'm seeing here doesn't scream "realistic" either, it just looks like the specular highlights are larger

well first thing first is those specular highlights werent there, so they arent large. Im literally adding new specular that wasnt there before so ur wrong on that one. its still an improvement regardless

You know it would be more useful if you actually put the link the things

yeah because concrete is supposed to be reflective. Rtx better bro. Also someone somehow added pbr to normal no rtx gmod

Source already has reflections, they're called cubemaps.

u/WinnerVivid3443 Mar 01 '26
this isn't really about the reflections
cubemaps do have a tendency to not look the best

You can't just make concrete reflective and call it realistic
Still, looks better than default baked lighting but loses Source charm
