Copying the lighting settings from hammer got it close to the original 2005 thumbnail of gm_flatgrass but not of modern source (i was trying to get the skybox but got the lighting color by accident)
You could try adding a Bloom effect and a Color Balance effect (was that what it was called?) and desaturate it slightly.
Love the GoldSRC UI, I don’t think I’ve ever really seen it used.
May I ask what the game is?
Im working on getting the general source jankiness in roblox for fun, will release once I get vgui remade (may be the olive version to match the goldsrc hud)
an update: lighting is still messed up due to me missing normal maps for all the materials and the shadows being weird
somewhat fixed the color and lighting
Damn, you beat me to it. Good luck!!
I was actually planning on working on a Source remake (still will since yours goes in its own direction slightly) but I am excited to see what comes of this.
There are some resources online like Crowbar that let you extract Source game resources, you could do that and find the textures manually.
that made it worse in my testing
source lighting is also more similar to voxel color-wise (i got it mostly accurate for now just need help with shadows)
