Make fullbright alpha mask with mask cutoff == 0 not generate shadows.
Adjust handling of ambient across forward and deferred again.
|
|
More tweaking ambient light.
|
|
Fix light atten and transmittance calcs breaking ambient color contrib to fog.
Needs to be tested on DRTSIM-415 or better to get legacy viewer settings that match EEP.
|
|
Modify ambient handling and forward projector lighting again to stamp out alpha fires.
|
|
Modify forward projector lighting to use falloff like the deferred lights.
Make tex cache not evaluate evictions for size during validation passes.
|
|
light contributions
(engages AMBIENT_KILL, SUNLIGHT_KILL, and LOCAL_LIGHT_KILL defines in shaders to accomplish
those tasks as required by each render mode).
|
|
Fix ambient light inputs to the renderer.
Fix 3rd sky shader w/ mistaken density mod conversion.
Make ambient clamp apply to all modes.
Tune ALM ambient clamp to match non-ALM.
|
|
|
|
Modify calc of sunlight to avoid clipping in gamma correct on values outside 0-1 range.
Modify shaders to put back ambient clamp tuned to be close to ambient contrib in low/mid lighting.
|
|
More shader tweaks to fullbright transport to get correct coloring while keeping fog fixes.
|
|
Make haze look more like WL.
Make lack of sun and moon mean black and fixed dir to prevent spooky underlighting.
|
|
Tamp down bloom so we don't have to redo ten thousand gloss maps.
|
|
Fix direct light matching across alpha/blended-material/deferred.
Get diffuse lighting to match from Low to Ultra.
|
|
Remove ambient clamp to keep shadows dark.
Partial fix for class 3 ambient term being wrong.
|
|
Don't ignore far z in culling.
Fix Mid lighting being very dark.
Partial fix for broken projectors with forward rendering.
|
|
Consistency across class2/3/ALM lighting.
|
|
about it).
Make a distinct class3/lighting/lightV which boosts to WL levels (* 2.0)
and make lighting without WL atmo enabled use class 2 or below.
Make forward shaders (alpha and materialF with alpha-blend mode on) more consistent with deferred lighting.
|
|
Restore light sum loops to fix broken ambient.
|
|
to WL).
Remove all refs to now unused calcFragAtmospherics.
|
|
All paths now use the same atmospheric transport calcs.
|
|
can be differentiated in nSight while debugging.

|
Replace old spot prio calc.
Replace fudge factors on light radius and falloff for deferred lights.
|
|
|
|
of atmosAffectDirectionalLight with sunlight_color that isn't updated correctly.
|
|
Fix name of attenuation setter used.
Fix flipped light vec.
Make class3 lights use shadows on projector ambiance too.
|
|
Fix the light_atten decsl for specular lighting too.
|
|
Fix lighting issues when using shaders, but not ALM.
Shader code cleanup (remove do nothing functions only in one file).
Fix obsolete comment to refer to correct storage for projector ambiance.
|
|
Fix up culling issues from perf work and fix Depth of Field rendering to get depth values properly.
Baseline for performance work.
|
|
Mods to improve alpha obj render performance.
Removes hacky fix for HUD elements getting atmospherics.
Re-orders rendering of glow to remove ~10ms/frame of shader re-re-rebinding.
Fix up default classes and basic shader loading (remove unused shared modules).
|
|
Fix side-effects of having both sun and moon as potential directional light contributors.
We pass an int to the shader indicating which to prefer instead of making per-pixel decisions
and pass the moonlight color/di independently.
Obsolete llsettingssky fade color which was unused elsewhere and cached for no reason.
|
|
Further tweaking of directional shadow sampling to balance between peter-panning and shadow acne.
Move stars to just this side of the sky some to reduce parallax.
Remove decodeNormF and uses of decode_normal in favor of unified use of getNorm
(try to help the Intel HD x000 compiler learn to link correctly).

SL-9851
Fix cloud shaders to ignore clouds when cloud_scale is 0.
Fix creation of heavenly body geo to avoid degenerate vector math
and not randomly flip orientation when crossing zenith.
Add sun_up_factor to eliminate sun glow around moon when sun is down.
|
|
Fix OSX shader compile bug from use of #if FOO instead of #ifdef FOO or #if defined(FOO)
preventing atmospherics (and thus ALM) from working on OSX.
|
|
|
|
Add new class3 shadow shaders for VSM shadows.
Add disabled shadow pass in WLSky for using above.
|
|
atten args.
|
|
|
|
|
|
Fix class 1 and 2 transport/gamma funcs and made usage consistent across all shaders.
Fix class1\environment\waterV reverting to old d1/d2 names for wave directions.

|
|
|
|
Eliminate 20+ callsites with copy-paste of getPosition and/or getNorm code.
Make pipeline use getShadowTarget/releaseShadowTarget consistently.
|
|
lighting shaders.
Also fix terrain response to atmospherics shaders (was failing to apply ambient on low end even when atmospherics was on).
|
|
Make shaders use consistent naming and parameter order for transport and atmospheric helpers.
Share transport and gamma correction code where possible.
Add lots of asserts and other validation for when things don't go as planned.
Engage dumpShaderSource to get more source output with shader compilation fail.
|
|
|
|
helper funcs.
|
|
add cloud_variance control for randomized perturbance of clouds to break up tiling monotony
|
|
More settings for rainbow/halo atmospheric effects, final default asset UUIDs, and shader mods.
