New mountable games

With community effort and permission from the respective game developers, 2 new games are now available to be mounted in Garry's Mod: Black Mesa and Military Conflict: Vietnam!

As with other mountable games, you will need to own them on Steam first, which will enable players to use maps and models from these games in Sandbox and other gamemodes.

HUD Improvements

Some default HUD elements received some polish - the weapon selector, damage indicators, health and ammo displays.

The ammo HUD now correctly displays ammo for certain modded weapon types that use secondary clips, the default weapon selector can now display more slots and scroll weapon selection when there are too many weapons equipped to fit on the screen.

The HUD now also scales better at 4K resolution, preventing certain elements such as Sandbox notifications and voice chat from overlapping the ammo HUD.

New content & content fixes

The Combine APC is now a built-in vehicle, right in the spawnmenu, fully driveable by the player.

There are also numerous bug fixes to existing models for various issues such as props becoming pitch black when resting on ground, fire effects not displaying correctly and spawning wrong gib models when broken.

Network protocol changes

This update brings significant under-the-hood changes to the game's networking, enabling faster network transfer speeds to reduce server join times, and removing a whole host of unnecessary networking done by various entities, hopefully reducing overall bandwidth usage, especially on initial player spawn.

This update also switches many game systems to use double precision time, which should help servers to not need to restart or change maps as often and improve overall game feel after playing for a while on the same map.

Smaller stuff

As usual this update also brings a huge amount of fixes and other smaller changes. Some optimizations to performance and memory usage as well.

You can find the entire change list below.

arrow_circle_up

Improvements

•
Reset effects of render.WorldMaterialOverride, render.ModelMaterialOverride and render.BrushMaterialOverride on disconnect
•
Prevent entity precaches on map start from calling GM:OnEntityCreated/Removed hooks
•
Add more entities to protected list (cannot be parented, overwritten or removed) - gmod_gamerules, ai_network, soundent, instanced_scripted_scene, ai_ally_speech_manager, scene_manager, npc_barnacle_tongue_tip
•
Entity:GetModel force lowercases weapon world models too (It was already forcing lowercase on all other entities)

•
Apply some random-ish patches from LuaJIT repo, including a memory allocator fix
•
Made Entity:SetLightingOriginEntity use model illumination position when given an entity with a model

Micro optimizations for Matrix & Entity:GetBoneMatrix

GM:HUDShouldDraw now gets called for cl_showfps panel (when active)
•
Applied correct rendering matrices for GM:PreDrawHUD and GM:PostDrawHUD, so calling cam.Start2D is no longer necessary
•
Moved calling of GM:PreDrawHUD slightly later, so it renders in the 2D view, just like GM:PostDrawHUD does
•
Moved GM:PostDrawEffects to be called slightly sooner than before, so it is called in the 3D view, not after it, and also is consistently called only when GM:PreDrawEffects is, not at all times.
•
Make game.GetMapVersion also return the BSP version
•
Allowed render.Capture to run with console open when a custom render target is set
•
chat.AddText now handles numbers like expected

•
Potential micro optimization for trace filter tables
•
mesh.Begin now throws errors with invalid primitive counts
•
Apply name restrictions to concommand.Add for certain invalid characters
•
Make joystick input add to mouse delta, not replace it - since the player can still use both at the same time (CUserCmd:GetMouseX)
•
Pass GM:AdjustMouseSensitivity's arguments to WEAPON:AdjustMouseSensitivity (Community Contribution)
•
IMesh:BuildFromTriangles will now read weights from util.GetModelMeshes - It will only read 2 weights max (as per hardware skinning limtiation), while util.GetModelMeshes can return up to 3!

concommand.Add now errors when given invalid parameter types
•
Added type checking to Entity:PhysicsInitConvex's second argument
•
render.ModelMaterialOverride will no longer override current override type

handyman

Fixed

•
Rework how trace whitelist works - it now better respects the collision group/mask, using it when testing for whitelist, instead of inverting it after the entity failed to pass the whitelist
•
Fixed a material refcount issue with render.MaterialOverride - occurred with dupe icon generator where the outline became missing texture with bigger dupes
•
Fixed potential refcount issues with render.MaterialOverrideByIndex, render.WorldMaterialOverride, render.ModelMaterialOverride, render.BrushMaterialOverride
•
Fixed IMaterial:GetShader on Linux SRCDS always returning "shader_error"
