wrefgtzweve asked to improve the ERROR_HANDLE_EOF when reading file warning, which doesn't say which file fails. robotboy655 said he'd try to get the path via the Win32 API; commit aa4090 tries to add it.

wrefgtzweve reported that NPCs measure melee distance to an object's center rather than its OBB, so large objects make melee NPCs such as antlions just stand around.

In #lua-help, full metal sergeant 228 asked whether there's a better way to do controllable textures, since he heard the default matproxy library is very slow, and noted LVS creates a material per entity. Artemking4 suggested instancing a material per usage from a base material and changing only what's needed. Asked by TankNut how slow matproxy must be for that to be the alternative, he said creating materials is "dirt cheap" because they are just containers for shader inputs.

In #developer-talk, Nak showed his LuaOS running DOOM at decent resolution with sound. A JIT-friendly self-patching block cache took it from 0.9M to 8M instructions per second; later a GTA beta loaded.

In #lua-help, 0d9b reported that util.JSONToTable turns strings that look like vectors into vectors even when called with ignoreConversions set to true. He asked whether this is intended, calling a JSON parser that mangles the output without an option to keep the original values "a bit useless for... parsing json". Artemking4 said he prefers MessagePack.

In #developer-talk, TankNut described problems with his physics-driven mech: movement is unpredicted, so multiplayer feels slow, and hook order breaks things because the mech moves in PhysicsUpdate after its turrets update in PlayerPostThink/Think. He added that the biggest problem in recreating player movement is that Lua has no equivalent of entity->PhysicsImpact, though ApplyForceOffset might be enough. He later said it may matter less, since it seems to be only for touch-related things.

Commit bb557c on main ports a fix for math.ceil/math.floor, adds self checks for corrupted map files and stops the load command from booting you out of the session when the save is missing.

In #next-update, Vitroze reported that PANEL:OnMousePressed now always calling MouseCapture breaks VGUI addons such as GmodAdminSuite. Rubat called it an issue with the mod but asked for a repro. Commit bb557c fixed the regression and Vitroze thanked him.

NovaDiablox asked to unbind F8 by default. robotboy655 declined: loading shouldn't boot you from the session; the engine wrongly checked mountable games for the "quick" save file. Commit bb557c fixes it.

Akabenko wrote on his request to add the 3D skybox to SSAO_DepthPass that a stencil is needed, because the game world is expected to always render on top of the 3D skybox.

Earu reported that a brush model with an $alphatest material leaks render state, so materials without $basetexture (vgui/white, surface.DrawRect, fonts) stop rendering. He provided a map for robotboy655; the issue was closed as completed the same day.

In #developer-talk, Nak released a NikNaks version with BSP physics parsing (not on the Workshop yet). Later he said BSP parsing is up to ~2x faster, BitBuffer 2–3x and mesh generation 3–5x.

drobotk's PR makes ENT:StoreOutput treat times=0 like times=-1, matching engine entities. Merged on 15 October (commit bb557c).

In #next-update, Earu asked why fading static props stop writing depth while they fade out. Artemking4 and Evgeny Akabenko explained that fading props are moved to the translucent pass, and translucent objects don't write depth. In the evening discussion, Rubat asked why transparent props would write depth at all, and said alpha testing is irrelevant for fadeouts. Earu said he would remove his issue. Evgeny Akabenko and Earu then discussed dithered fades combined with TAA.

In #next-update, TheSoulClock said the new x86-64 branch crashes his low-end laptop every time he joins a big server; Rubat said crash logs would be needed to do anything about it. Nykez said a Mac user of his started crashing on load, and WinterPhoenix suspected (not yet verified) a render.Capture crash on x86-64 Linux.

In #developer-talk, Astralcircle's game ran out of memory around poster 10 while making a huge map overview. Rubat pointed out that poster can leave the tiles uncombined via its second argument. Astralcircle then made a 20k screenshot of gm_construct.

Commit 9ecf4a on main makes prediction errors on arrays include the index for ints and floats, fixes a couple of multicore rendering memory leaks and a crash in render.UpdateScreenEffectTexture.

In #developer-talk, Harry said he multithreaded SV_ComputeClientPacks, increasing performance by over 50% and running a solid 64 tick with 128 players. He is looking into going past 128 players; he expects the entity limit to be the main problem, since it can't be raised without client changes.

Commit 831250 on the x86-64 beta switches the Chromium (CEF) process to a newer GCC.

RaphaelIT7 asked for a Lua binding of CBasePlayer::FindUseEntity. robotboy655 closed it with a link to Player:GetUseEntity.
