JAVITA 1.0.1

JAVITA 1.0.1

Bug-fix release. Install the new VPK over 1.0.0; settings, saves and texture cache are kept.

Fixed

• Fog. Fog now fades out gradually instead of ending at a hard edge, and everything
  drawn is affected by it, including the batched world geometry that previously ignored it.
  On Hoth the render distance cut no longer shows as a dark band behind the fog.
• Frozen mission select. The tier menu showed a stuck frame while it compressed its
  planet art on the first visit. It now shows a loading screen. The wait itself is
  unchanged — see Known issues.
• Menu characters. Models shown on the debrief and saber screens were being folded
  into the world geometry batch, which is not valid for a menu and could draw them wrong.

Known issues

• The first visit to each tier menu is slow while its art is compressed and cached.
• Changing texture detail (r_picmip) discards the texture cache, so the loads after it
  are slow once per area.
• Mirrors and portals draw unclipped.
• Dynamic glow is unavailable.

JAVITA 1.0

Star Wars Jedi Knight: Jedi Academy — single-player
Built on OpenJK with a native sceGxm rendering backend.

Thanks to the testers who played the broken builds on real hardware and reported what they
saw: BlackOp, Miso, Celtic Gaming, Cobra, Gene Parmesan, HoldenWave, midniteneon,
Og_Olibernd, Snk_knS and EchoFox. This release is as much theirs as mine.

Requires

• PS Vita / Vita TV with HENkaku or h-encore
• Jedi Academy game data (assets0.pk3 – assets3.pk3) from your own PC copy,
  placed in ux0:data/JAVITA/base/

Highlights

• Multithreaded renderer — game logic, rendering and audio each on their own core
• World geometry batched into GPU buffers, including fogged areas
• Character draws merge across NPCs that share materials
• Fog volumes render through the real Q3 fog pass again
• Menu transitions show a loading screen instead of a frozen or blank frame

Frame rates are substantially higher and steadier than 0.9.1
(measured on a 500 MHz-overclocked unit; stock clocks run lower).

Fixed since 0.9.1

• Save/checkpoint scripting broke after dying and reloading (ICARUS state survived a reload)
• Trees and props from the previous map appearing in the next one
• Fog ending in a hard grey edge instead of a gradient (rail, tram)
• Sky missing on several maps
• White or frozen frame between mission end, debrief and map load
• Debrief menu load time cut from ~24 s to ~2.5 s
• Decal depth-bias leaking onto the whole scene (z-shimmer after scorch marks)
• Two out-of-bounds reads in savegame code
• Shadows respect the in-game setting again (blob shadows on by default)

Known issues

• Mirrors and portals draw unclipped (no user clip planes in the GXM backend)
• Dynamic glow is unavailable

Install

1. Install JAVITA.vpk with VitaShell
2. Copy the four assets*.pk3 files to ux0:data/JAVITA/base/
3. Launch — controls and tuning are in the README

Upgrading from 0.9.x: install over it; saves and settings carry over.

JAVITA 0.9 - ALPHA

First public alpha.

ONLY for playtesting before 1.0 ! It's not a final release yet!

Install

You need your own legally-owned copy of Jedi Academy (eg. from Steam).

1. Install JAVITA.vpk with VitaShell.
2. Copy assets0.pk3, assets1.pk3, assets2.pk3, assets3.pk3 from your PC copy's
   GameData/base/ to ux0:data/JAVITA/base/.
3. Launch from the LiveArea.

No libshacccg.suprx needed — the shaders are compiled ahead of time and built into the binary.

The first visit to each level is slow. Textures are re-compressed to DXT once and cached to
ux0:data/JAVITA/texcache_dxt/. Later loads of that level read the cache and are much quicker.

What's in it

• Native sceGxm renderer. The renderer talks to the Vita's graphics API directly — there is no
  OpenGL translation layer in the build.
• Threaded. Rendering, sound mixing and character skinning run off the main thread.
• Static world geometry in GPU buffers, so level surfaces don't get re-uploaded every frame.
• Static prop batching, so the many copies of one tree or rock a map places share a draw
  instead of taking one each.
• DXT texture cache on the memory card, which is what makes the second visit to a level fast.
• Vita controls — dual-stick, rear touch panel with a combo layer, and an on-screen keyboard
  console on Start + Select.
• Aim assist, on by default. It gently steers your view toward a nearby enemy and slows your
  look speed so the sticks overshoot less. g_aimAssist 0 turns it off.

Experimental

Off by default. Turn them on from the console or openjk_sp.cfg, and expect artefacts.

Setting	What it does
cg_shadows 2	Stencil shadow volumes. Sabers and blaster bolts move the shadow.
cg_shadows 3	Projected shadows. Experimental
r_shadowAlpha	How dark a stencil shadow lands (0.22 default).
r_shadowExtrude	How far a shadow reaches past the ground (96). Raise it to catch walls — too far and shadows show through geometry.
cg_shadowCasterRange	Characters past this distance keep a blob instead (1024).

Known issues

• Stencil shadows land on the ground and only reach walls as far as r_shadowExtrude allows.
  There is no distance fade, so a distant character's shadow pops out rather than fading.
• Frame rate varies by map. Open, prop-heavy areas run below 60.
• Loading a level for the first time can stall noticeably while textures are cached.
