Raw Blame History

2020-02-24 ericw-tools 0.18.3-rc1

Note:

  • Windows builds are 64-bit only for this release. I'm planning to restore 32-bit support but dropping it for this release made a dependency update easier. Not sure how many users this affects - let me know if it is a problem for you.

Bug fixes:

  • qbsp: make origin brushes not use hiprotate bounds expansion (c30a0a4)
  • qbsp: fix external maps with no worldspawn brushes (5e74b4d)
  • qbsp: fixes for -wrbrushes (cefd20c, 1577981, 209d481)
  • qbsp: fix relative paths for .wad files (79d3aa9)

  • light: add _light_alpha func_group key for making faces translucent for light (d6136c1)
  • light: bounce: also make shadow-casting bmodels bounce (unless they opt-out with _bounce -1) (5010dc9)
  • light: support "_suntexture" key on "_sun" "1" entities to limit them to being cast from a specific sky texture. (f220b2f)

  • light: remove 65536 ray limit, fixes #276

  • bsputil: "--check" option logs world mins/maxs
  • bsputil, bspinfo: can now read Q2 BSP files

2017-09-17 TyrUtils-ericw 0.15.11

2017-07-30 TyrUtils-ericw 0.15.10

  • light: add "_shadowworldonly" bmodel key - only cast shadows on world, not other bmodels.
  • light: switchable bmodel shadows (requires QuakeC support, see light manual).
  • light: accept "_minlight" in worldspawn as an alias for "light"
  • light: handle degenerate faces, print out the vertex coordinates
  • qbsp: misc_external_map prefab system (see qbsp manual)
  • qbsp: don't write unused texinfo
  • qbsp: rewrite outside filling similar to q3map
  • qbsp: revert change to SubdivideFace which was increasing faces a bit (see 53743dd)
  • qbsp: add -expand option to dump the hull expansion to a "expanded.map", from q3map
  • qbsp: add -leaktest option to abort compilation when a leak is found, from qbsp3
  • qbsp: fix handling of duplicate planes, which was causing id1 maps to leak
  • qbsp: try to get more reliable leaf content assignment (see a910dd8)
  • bsputil: --check: print BSP tree heights at the first few levels of the tree
  • bsputil: --check: check for unreferenced texinfo, vertices, planes
  • bsputil: --check: print number of used lightstyles
  • misc: travis-ci now runs qbsp on all id1 maps, the build fails if any maps leak

2017-06-10 TyrUtils-ericw 0.15.10-beta2

  • light: styled lights no longer bounce by default, set "_bouncestyled" "1" to enable.
  • qbsp: map format conversion: fix reversing of epairs in converted maps
  • qbsp: func_detail rewrite to fix vis issues with previous version. func_detail no longer seals maps.
  • qbsp: add -omitdetail to omit all func_detail entities from the compile
  • qbsp: new func_detail_illusionary entity. func_detail variant with no collision (players / monsters / gunfire) and doesn't split world faces. Doesn't cast shadows unless enabled with "_shadow" "1". Useful for hanging vines. Still creates BSP leafs. (Possible enhancement: avoid creating new leafs and just insert marksurfaces into existing leafs?)
  • qbsp: new func_detail_wall entity. func_detail variant that doesn't split world faces. Useful for when you want a decoration touching a floor or wall to not split the floor/wall faces (you'll get some overdraw instead.) If it completely covers up a world face, that face will get clipped away, so it's not suitable for fence textures; see func_detail_fence instead.
  • qbsp: new func_detail_fence entity. Similar to func_detail_wall except it's suitable for fence textures, never clips away world faces. Useful for fences, grates, etc., that are solid and block gunfire.
  • qbsp: add -forceprt1 option to generate a .prt file that GTKRadiant's prtview plugin can load (but will be unusable by vis). When func_detail is in use you normally get a PRT2 file that ptrview can't load.
  • qbsp, light: allow _shadow -1 to stop a func_detail from casting shadows

2017-03-26 TyrUtils-ericw 0.15.10-beta1

  • light: fix Linux binary
  • light: lights with a lightstyle now bounce
  • light: new sample point positioning code
  • light: per-light "_bouncescale" key
  • qbsp: origin brush support
  • qbsp: add -omitdetail option, strips out all func_detail brushes
  • qbsp: add -convert option for converting between .MAP formats

2016-11-20 TyrUtils-ericw 0.15.9 release

  • light: fix black fringes on bmodels that are touching against the world
  • light: light passing through glass lights up the back side
  • light: bmodels with "_alpha" < 1 and "_shadow" "1" set cast tinted shadows
  • qbsp: support Quake 3 "Brush Primitives" .MAP format
  • qbsp: save "_mincolor" for func_detail/group to the .texinfo file, now used by light
  • qbsp: performance improvements

2016-10-03 TyrUtils-ericw 0.15.8 release

  • light: fix black noise in some cases when using -bounce. (reported by Pritchard)
  • light: try to limit artifacts caused by "too many lightstyles on a face", by saving the 4 brightest lightmaps. The previous behaviour was random, so you would likely get bad artifacts when that warning occurred.
  • light: restore and expand the "unmatched target" warnings. Now checks "target", "killtarget", "target2", "angrytarget", "deathtarget". Also checks for any "targetname" that is never targetted.
  • light: restore support for skip-textured bmodels with "_shadow" "1". This is only supported on bmodels where all faces are textured with "skip".
  • light: add "_lightignore" model key, makes a model receive minlight only.
  • qbsp: accept absolute path to map (reported by lurq)

2016-09-09 TyrUtils-ericw 0.15.7 release

Bugfixes:

  • light: fix shadow-casting bmodels that touch the world from messing up sample points on world faces, and prevent the world from messing up bmodel sample points (regression in 0.15.5)
  • light: clamp lightmap samples to 255 before smoothing, downscaling. reduces jaggies in cases with very bright lights casting hard shadows.
  • light: fix order of "_project_mangle" value to be consistent with "mangle"
  • light: various crash fixes
  • light: minlight no longer bounces

Performance:

  • light: new, faster raytracing backend (Embree)
  • light: estimate visible bounding box each light by shooting rays in a sphere. this gives a speedup similar to vised maps in 0.15.5, without requiring the map to be vised. As a downside, there is a small chance of introducing artifacts where lights cut off too soon. Disable with "-novisapprox".
  • light: bounce lighting code redesigned to use less memory

Other:

2016-06-17 TyrUtils-ericw 0.15.6 release

  • rebuild OS X binary as it was built in debug mode by accident

  • light: use vis data to accelerate lighting

Bugfixes:

  • vis: fix ambient sounds when using func_detail, broken in tyrutils-ericw-v0.15.3

New features:

  • light: new "-surflight_dump" command-line flag. Saves the lights generated by surfacelights to a "mapname-surflights.map" file.
  • light: new "_sunlight3" and "_sunlight3_color" keys. Same as "_sunlight2", except creates suns on the bottom hemispere ("_sunlight2" creates suns on the top hemisphere.)
  • build: support compiling with Visual Studio

Bugfixes:

  • light: fix antilights (broken in last release)
  • light: fix _mincolor to accept 0-1 float colors
  • light: fix surface lights on rotating bmodels from incorrectly spawning lights near the origin

2015-08-09 TyrUtils-ericw 0.15.2 release
