In #developer-talk, Xenthio explained that his Source 2-style renderer is a replacement for shaderapi plus his own lightmap baker. Baking takes about 40 seconds on a map's first load; after that the map opens instantly.

In #developer-talk, Nak showed 5 maps rendered at 187 FPS with his pocket map script, saying baking static meshes helps performance a lot. Later he said he'd combine his RTS base with the pocket map script.

In #developer-talk, Bloom said he is building an app (on the French side) that imports FBX, OBJ and XPS models into GMod as playermodels automatically. It learns from each import; after almost 200 imports the automatic result is nearly perfect. Annie suggested a guided porting interface would be less bug prone.

In #developer-talk, nighty said the main branch uses LuaJIT 2.0.4 and the x86-64 beta uses LuaJIT 2.1 beta 3. Zaurzo added that 64-bit main uses the same LuaJIT as x86-64. nighty described his lua_shared fork: it targets a custom language but should run existing GMod Lua exactly like stock, and isn't public yet. Its threading is worker-based, with message passing between separate Lua states. He also showed Jolt physics experiments.

In #developer-talk, Redox shared a project "made in gmod" that ran smoothly with a group of players. TankNut, after looking at it, said "they've decompiled the game and ported it wholesale". A1steaksa said he isn't impressed if it's AI-made, while Redox said it's too polished to be pure slop. TankNut added he is more interested in the original Ace of Spades than "the Jagex abomination".

In #next-update, Beelzebub shared silk.bzbb.dev. The day before, YohSambre had said he missed the old icon web UI and Billy pointed to the in-game derma_icon_browser; Beelzebub said he was forking an icon browser UI.

In #developer-talk, Nak explained his navigation system to Zemen. It runs a double A* search from start to goal and from goal to start, meeting in the middle ("a trick GPS use"). The search tracks polygon entry points, and the system reads the map's AIN info_nodes. NPCs such as the 200 antlions in his video run a "dumb" AI while waiting for a path, so they seem to react immediately.

In #developer-talk, Asphaltian posted the v0.2.0 release of VPhysics-Box3D. Earlier, on 16 Oct, BlueShank had argued that Box3D deviates too much from vphysics to be a drop-in replacement.

In #developer-talk, Retcon shared a komstation article about his mod, a Garry's Mod-style sandbox for the PSP.

In #developer-talk, Callum showed GMod's main menu fully recreated with VGUI. He said VGUI will always be a little slower but it's fine for a main menu: about 300 FPS on the DarkRP server list versus 500 with HTML. Akiko noted that one upside of the HTML menu is it immediately shows when the HTML backend is broken.

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 #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.

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.
