Make spot shadowing more consistent.
|
|
Rearrange ordering of scale down of light in class1 as well.
|
|
Fix skydome VB generation to cover entire range of phi (give sky pants).
Add shader code to fade out clouds to simulate old look at altitude.
|
|
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.
|
|
Don't step on SUNLIGHT_COLOR uniform w/ syncLightState competing set.
Put drawpool alpha render loop lighting setup changes as they were
(this will give back some performance and possibly require reopening 10566).
|
|
Remove shadow influence on ambient term causing inverted lighting in extreme setups.
|
|
|
|
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).
|
|
Tie using deferred rendering in water reflection/distortion map generation to debug var again
(claw back some performance lost to doing post-deferred in water map generation).
Edit softenLightF for class1/class2 to make them comparable again.
|
|
Fix lighting and gamma correction differences between deferred and forward rendering including materials objects.
Verify 10612 and 10500 remain fixed.
Make sure all necessary deferred shaders get the atmospheric uniform updates for doing frag-based atmospherics.
|
|
Fix shadow sampling min with caster dp and offset tweaks.
Fix moon direction not being transformed as the sun dir is.
Fix colorspace issue causing some objects to render grayish instead of blackish.
|
|
Replace clamp on height in atmospherics calcs on fragment shader path.
Fix colorspace conversions in material shaders in forward rendering mode.
Fix deferred shaders not setting the sun_up_factor uniform and getting moonlight instead of sunlight.
|
|
Another pass at playing with shadow_offset/bias to balance between peter-panning and shadow acne while sun and/or moon are near the horizon.
|
|
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.
|
|
Fix bug with setting texture matrix for rigged mesh.
Fix z-fighting between sea and sky in ALM by cheating sky, stars, and moon using gl_FragDepth.
Fix handling of atmospheric haze glow w.r.t independent sun/moon positioning
(we can no longer depend on them being mutex to each other).
|
|
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).
|
|
Fix positioning of sun/moon discs w.r.t atmo haze glow.
Disable killing glow when sun is not up.
|
|
Modify sun disc shader to better position itself within the sun glow and to
fade as the sun approaches the horizon (to mask where the position difference is greatest).
|
|
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.
|
|
Use clamp on dot product of view and light norm to eliminate 2nd halo.
|
|
Use clamping on dot product to determine halo TCs to fix abrupt cutoff at dot == 0.
Ifdef around engaging advanced atmo which is not ready for primetime yet.
|
|
blocks in several shaders).
|
|
atten args.
|
|
De-duplicate ambient occlusion shader code and move to new aoUtil.glsl
Split shared shadow tap funcs into shadowUtil.glsl
|
|
|
|
Modify handling of directional light to prefer sun when it is up but use moon dir/color when it is alone in the sky.
Modify handling of shader in shaders to get some shadowing of ambient and nighttime shadowing.
|
|
Plug more holes through which env ambient terms were finding their way into lighting calcs for HUDs.
Fix up mismatched indenting (tabs v spaces) on several shaders.
|
|
Fix fullbright transport transposed args and use display gamma for post-deferred gamma correction.
|
|
lighting pipe.
|
|
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.
|
|
|
|
|
|
Port over transport, gamma, atmospherics shader stub updates for per-fragment atmospherics.
Fix bindings of current/next noise map when current and next are the same (select only one and force blend factor to 0).
|
|
De-hackify WL additive to get better match between ALM and non-ALM rendering
without bringing back SL-1491 lens flare bug.
|
|
|
|
helper funcs.
|
|
density tab.
Make frag shader version of vert WL shader to include rainbow/halo effect in non-advanced WL sky.
|
|
add cloud_variance control for randomized perturbance of clouds to break up tiling monotony
|
|
between maintaining old look of WL settings and fixing SL1491 lens flare bug
|
|
Modulate class1 softenLight atmospheric additive by specular.a (same fix as for class2).
Clamp additive color to <= vec3(0.2) to avoid similar artifacts in non-deferred render path.

could be used by HUDs
Make sky and cloud shaders use common scaleSoftClip implementation in gammaF.glsl
