Looks very cool...
but it seems to rely on specific hardware..... so you may be restricted by which PCs will run these mods..
My nephew ( and I encourage and pump him a lot ) is a DOOM nerd...
We already run all possible mods for modern doom in which light bumps and shade maps looks really cool.
Almost like these . but ... they do not require any particular hardware....
A good PC should be enough.. even iGPUs can do them
Get yourself if not already a good engine like
https://zdoom.org/downloads (or ZANDRONUM)
Search the best maps to suit your prefs.. like COD (Call of Duty) weapon arsenal
AltBrightmaps for Doom1 and 2 +
brightmaps and lights doubleDHTP
and HIGH RESOLUTION textures and maps..
There is already a good old Quake high resolution equivalent..
You will have even better results than above.. in cheap hardware..
The kid loves them.. total doom nerd
