[HRCS] HL2 Black Mesa East Interior (d1_eli_01)

This is a map from Half-Life 2's campaign. I strongly recommend having played the original game first before experiencing this.

Another map where I push the Source Engine to its limits using GMod's 64bit tools. Features 256x256 resolution cubemaps and the highest resolution shadows possible without crashing VBSP. Also includes extremely minor fixes and a few edited/recompiled models to enhance collisions and shadows.

Map name is d1_eli_01_hrcs and can be found in the "Half-Life 2" map section.

I may have gone overboard with enabling shadows for dynamic props, causing the airlock and Eli's lab to look funky. I might come back and fix that in the future, depending on how I feel about it. I also might come back and make all physics props static so that they cast more "realistic" shadows, but I wanted to keep the original functionality of the map intact for this version.
In addition to adding brush based translucent shadows, I have adjusted the dynamic prop shadows and turned physics props that are out of the playable space/set to be stationary into static props so they cast ray-traced shadows.

Compiled for LDR & HDR and retains full functionality as long as you have Half-Life 2 purchased & installed on Steam, and mounted in Garry's Mod. Also includes a navmesh.

Known Issues:

• Alyx may not play some animations and will T-Pose. This can be fixed by un-mounting Half-Life 2: Episode 1 and Half-Life 2: Episode 2. It's also very possible that any addon that modifies Alyx's AI or model will cause this issue too.
  
• The single blast door that Mossman opens to the first elevator gate opens and closes extremely quickly. I believe this is due to a desync between the blast door model and the func_door entity, but only for that door. This may be related to the very hacky map compilation setup I had to do for this map, despite this bug not existing with the raw BSP file straight from my modified VBSP (read the trivia for more details).
  
• Dr. Mossman may not enter the elevator. If you encounter this, please leave a comment, so I can go bash my head into a wall repeatedly.

Completing the level as you would in Half-Life 2 will take you to map d1_eli_02_hrcs if you are subscribed to it.

Trivia:

• Without cubemaps, the map size is ~ 373MiB (This size is caused from the HDR & LDR lightmap)
  
• You can shoot through the elevator gates now
  
• Whomever was responsible for compiling the maps for HL2:U either forgot or didn't know to have models cast shadows when compiling with VRAD. You can see that in the screenshots (that haven't been suspiciously removed) of my other maps too.
  
• This map is not from a decompile
  
• New as of 06-2024: Between August of 2021 and now, a bug has been introduced into Garry's Mod's VBSP executable (32bit and 64bit) that seems to only affect this map; Mossman will do her introductory sequence, raise the elevator, but will not enter it when it arrives. I have no idea how a VBSP bug could cause this but using Half-Life 2's or the 2013 Multiplayer SDK's VBSP circumvented the issue. So, to compile this map, I had to edit the code of the Source SDK 2013 Multiplayer VBSP code to remove a silly limitation around static props that Garry's Mod VBSP has a workaround for, compile that code, and then carefully juggle the map between an ancient 2013 SDK workspace and my usual Gmod workspace. I would not be surprised if somewhere in this chain is why there is that bugged door that moves too fast. Shoutouts to ficool2 for making a 64 bit Garry's Mod version of Hammer++, I will be using that from now on from this point, it made this process a lot easier.
