Option 1 (AI Upscaled Textures)

This option is for people who wish to keep the exact "feel" of the game but would like sharper textures.

Navigate to your Steam Library folder and and locate the Half Life folder (typically: C:\Program Files (x86)\Steam\steamapps\common\Half-Life)

Inside you will find a folder called "valve_hd". Copy the entire folders contents (not the folder itself) into the "valve" folder on the Quest (This may take a long time). We recommend doing this via standard Windows Explorer rather than SideQuest.

Download the AI Upscaled Textures from here

In the Zip file you will find the folder "STEP 4/valve". Copy the contents of this folder (not the folder itself) into the "valve" folder on your Quest (This may take a long time).

In the Zip file you will find the folder "STEP 5/valve". Copy the contents of this folder (not the folder itself) into the "valve" folder on your Quest (This may take a long time).

Start Lambda1VR. Go to options, Video and tick "allow materials".

Option 2 (HL GOLD Textures)

This is a pack painstakingly adapted from HL:GOLD by "Crowbar" by close project friend VR_Bummser. He had to rename some hundred textures (about 900) by hand to make them work correctly in Lambda1vr. It now uses xash engines system for textures replacement instead of the detailed_texture method. This pack will improve the look of HL drastically . The textures are sharper and clearer, while they stay mostly very true to the original (there are some colour and style changes).

​ This customized HL: Gold_hd pack includes:



HD Textures.



Some remastered sound effects, but true to the original.



Improved sprites and decals.



Higher resolution skyboxes.



New fanart start screen background and fancy startup music from the PS2 version of HL.



G-Man and HEV suite are super high poly models (The few occasions you see those two , it's nice to have them look very good.)

Follow the below steps to install:

Download the HL_Gold_HD from here

Extract the zip "HL_Gold_HD" to your PC. Copy the whole HL_Gold_HD folder to your Quest to the folder "xash" so it looks like this quest/xash/HL_Gold_HD (CAN TAKE UP TO 45 minutes to copy depending on your USB port speed)

Download and copy this file to the xash folder on the Quest (overwriting the existing commandline.txt). Alternatively replace the contents of you existing commandline.txt with:

xash3d -log --supersampling 1.25 --msaa 2 --cpu 4 --gpu 4 -game HL_Gold_HD

xash3d -log --supersampling 1.25 --msaa 2 --cpu 4 --gpu 4 -game HL_Gold_HD Start Lambda1VR. Go to options, Video and tick "allow materials".

Optional: If you already played without the hd textures and wanna use your old savegames, copy your old savegames from xash/valve/saves to hl_gold_hd. Copy the whole folder.

To switch back to original textures download and copy this file to the xash folder
