Correct math requires the ambient component of the lightgrid to be zero
in that case. However, q3 ignores lightgrid cells with all zero ambient
value, EVEN if the directed value is nonzero.
This change sets the ambient value to #010101 if it'd be pitch black. This
should be a minimal change without affecting light hue that fixes
lightgrid rendering. In engines like DarkPlaces, almost no map should
look different from this.
Fixes https://gitlab.com/xonotic/netradiant/-/issues/137
fix -bsp crash with .bsp sent as map path
* fix: qer_editorimage, q3map_lightImage etc work with file names, containing period
(i.e. 'file.name.ext' names; don't StripExtension() twice in ImageLoad() for that)
similar to -lightmapsize N: Size of lightmaps to generate (must be a power of two)
but instead of native external lightmaps enables hack to reference them in autogenerated shader (for vanilla Q3 etc)
* -backsplash (float)scale (float)distance: scale area lights backsplash fraction + set distance globally
(distance < -900 to omit distance setting); def = 1 23; real area lights have no backsplash (scale = 0)
q3map_backsplash shader keyword overrides this setting
Radiant:
binds...
* alt + m1 click/drag in component modes: select objects
misc...
* fix: selected entity and brush numbers display in 'Find brush' dialog
* prefer to display texture width and height in status bar over name (PANGO_ELLIPSIZE_START)
* allow search shortcut (ctr+f in win) in entity inspector -> entity class list
* fix: don't save empty group entities (but worldspawn)
* new slightly less careful, but much faster lightmaps packing algorithm (allocating... process)
* -slowallocate switch to enable old lightmaps packing algorithm
* Subsampling...collapsing...sorting...allocating...storing...projecting... timers
* -brightness 0..alot, def 1: mimics q3map_lightmapBrightness, but globally + affects vertexlight
* -contrast -255..255, def 0: lighting contrast
* packer improvements
Radiant:
binds...
* entity inspector: Tab enters Key field, toggles between key/value fields; Del deletes keys; Esc quits
misc...
* improved mwheel 2d zoom by Neumond
* +makeRoom: like hollow, but extrudes faces outwards; for making rooms
* deactivating tex dirs tree after loading dir, so SPACE and ENTER aren't broken for 2D after that
* Regular, RegularLeft layouts: smaller console, bigger tex browser
* Rotate, Scale dialogs: values aren't erased on Enter, OK, Apply (are on cancel, esc)
* Rotate dialog: fix: new value in focused field wasn't taking in account on Enter
* +updating texture directories list on 'flush and reload shaders' (reloading shaderlist aswell)
* NumLock perspective window fix
* ctrl+k(ConnectEntities): friendlier to complex connections, takes in account existing keys
(priority: target > targetname > none)
* +'all Supported formats' default option in open dialogs
* defaulted show light radii
* camera fov: 90->110
* cubic clip: off by default; bigger def dist; fixed button's shortcut tip
* prefs: Min & Max texture thumbnail size + dependant on scale;
def = *scale .5, min 48, max 160 (makes range 96-320 visually differentiated)
* shot down spammy warning about samplesize for lmsize<=128; -debugsamplesize to show
* numBspModels ('brusmodels') stat emitting
Radiant:
misc...
* filters toolbar (disableable)
* fix: shift + m1 click in tex browser to open shader in internal/external editor;
defaulted internal; focuses on wanted shader; correct opening/saving
* fix: angles "0 x 0" autoconvert to angle "x" on transform (was getting deleted w/o a trace)
* -bounceColorRatio 0..1 (ratio of colorizing sample by texture)
* -debugclip: autoclip debug, uses shaders debugclip, debugclip2
* >2GB makefile option, allows up to 3GB ram on 32bit, 4GB on 64bit
* speedup patch to use fast sqrt at some points of light phase, where precision is not needed
Radiant:
binds...
* paste to camera - shift+v (alt+v was leading to texBro-View menu)
fix * q3map_remapshader remaps anything fine, on all stages (effect is: postrenaming shader when things are have been done)
* typo at -dirtmode
Radiant:
misc...
* translucent textures are visible, while selected, too; +matching trans polys are visible simultaneously
* native surfaceparm noob support (no -custinfoparms needed)
* -noob in bsp phase: assign surfaceparm noob to all map surfaces
* surfaceparm ob: skip assigning surfaceparm noob with -noob on that
* farplane modes: radius+radius, origin2origin, exact (add r/o/e to the number to enable), < 0 works too
* samples+filter - enabled again, makes sense
* -vertexscale
* fixed -novertex, (0..1) sets
* quick q3map_novertexlight (?)
* fixed _clone _ins _instance (_clonename)
* -nolm - no lightmaps
* ent keys aliases:_sa - shadeangle;_ss - samplesize
* -shift N -shift X Y Z: shift whole map to some coords
* more fogs (256) (ingame appearence lots of ones might be bugged due to engine arrangement, needs testing)
* q3map_remapshader remaps anything fine, on all stages (effect is: postrenaming shader when things are have been done)
* fixed 'unknown argument 1' at -lightanglehl
* -nocmdline writting to worldspawn
Radiant:
binds...
* wasd camera binds, c - deSelect, z - delete
* ExpandSelectionToEntities - shift+e
* make detail - alt+d
* arbitrary rotation - shifr+r
* arbitrary scale - ctrl+shift+s
misc...
* fit width, fit height butts in surf inspector (for trims) (saves scales ratio)
add old TODO with ideas
