Reworked the reflection reference offset/scale behavior to re-integrate into the editor interface via button(and work)
Hid irrelevent fields from given probe types.
Filter out editPosOffset and bake button fields from being saved to avoid weird loading behavior
Temporarily disabled logic for forward render of probes to avoid data mangle. TODO: fix up forward once deferred math is locked in
Split probe modes out into distinct environmental probe objects
Removed the probes from tracking their own baked cubemap file paths and instead have a pref store it
Removed old probe shaders and materials that aren't used now.
Fixed mLastConst memory leak by removing nono line.
Shifted update of probe data to be triggered by probe changes.
Pack probes into the data arrays forward-first instead of keeping strict indicies.
todo: move bake to probeManager, clean up old/commented code, remove old probeMaterial stuff
1) kill off extraneous cubemap and irradiancecubemap source-to-shader variable ties
2) use the cubemap arrays (renderdoc for instance doesn't list them as being input at all if they're never used)
3) use the vert file
- Supports GL, D3D9 & D3D11
- Extends vertex formats & shadergen to support blend indices and weights
- Adds basic support for using 4x3 matrices for shader constants
- Supports software fallback
renderPrePassMgr.cpp related:
A) shifting .addFeature( MFT_XYZ); calls from ProcessedShaderMaterial::_determineFeatures to ProcessedPrePassMaterial::_determineFeatures
B) mimicking the "// set the XXX if different" entries from RenderMeshMgr::render in RenderPrePassMgr::render
C) fleshing out ProcessedPrePassMaterial::getNumStages() so that it shares a 1:1 correlation with ProcessedShaderMaterial::getNumStages()
D) causing inline void Swizzle<T, mapLength>::ToBuffer( void *destination, const void *source, const dsize_t size ) to silently fail rather than fatally assert if a source or destination buffer is not yet ready to be filled. (support for #customTarget scripted render targets)
Reflections:
A) removing reflectRenderState.disableAdvancedLightingBins(true); entries. this would otherwise early out from prepass and provide no color data whatsoever.
B) removing the fd.features.addFeature( MFT_ForwardShading ); entry forcing all materials to be forward lit when reflected.
C) 2 things best described bluntly as working hacks:
C1) when reflected, a scattersky is rotated PI along it's z then x axis in order to draw properly.
C2) along similar lines, in terraincellmaterial, we shut off culling if it's a prepass material.
Skies: scattersky is given a pair of rotations for reflection purposes, all sky objects are given a z value for depth testing.
Phase 1: buffers
engine:
provides the following hooks and methods
A) render target "color", and "matinfo". these correspond to texture[0] = "#color"; texture[2] = "#matinfo"; entries in scripts
B) utilizes the independentMrtBitDepth method added GarageGames#857 to set color to an 8RGBA if cards support it
C) adds an RenderPrePassMgr::_initShaders() method to support void RenderPrePassMgr::clearBuffers(). This operates as a pseudo-postfx by rendering a veiwspace plane which fills the screen, then calls a shader which fills both the introduced rendertarget buffers and the prepass buffer to relevant defaults (white with full alpha for prepass, black with full alpha for color and material respectively)
script:
\game\tools\worldEditor\main.cs adds additional hooks similar to GarageGames#863 for colorbuffer, specular map, and backbuffer display
\game\core\scripts\client\lighting\advanced\deferredShading.cs adds the clearbuffer shader, visualizers, and the ShaderData( AL_DeferredShader ) + PostEffect( AL_DeferredShading ) which combine the various buffers into the output which reaches the screen under normal conditions, as well as the extended debug visualizers.
again, note the lines
texture[0] = "#color";
texture[1] = "#lightinfo";
texture[2] = "#matinfo";
target = "$backBuffer";
in particular for the core tie-in.
shader:
\game\shaders\common\lighting\advanced\deferredColorShaderP.hlsl
\game\shaders\common\lighting\advanced\gl\deferredClearGBufferP.glsl
the previously mentioned shaders which clear the buffers to specified colors
\game\shaders\common\lighting\advanced\deferredShadingP.hlsl
\game\shaders\common\lighting\advanced\gl\deferredShadingP.glsl
the tie-in shaders
the rest are visualizers
purpose: to expose methodology that allows one to render color, lighting and material information such as specular and gloss which effect the result of both when combined
long term intent: the previous prepass lighting methodology while serviceable, unfortunately had the side effect of throwing out raw color information required by more modern pipelines and methodologies. This preserves that data while also allowing the manipulation to occur only on a screenspace (or reflected speudo-screenspace) basis.
Caused by a wrong target size. (probably it was ok on the very old OpenGL 1.5 version)
Before fix, wrong behaviour:

After fix, all right:

OpenGL and DirectX11 not support FFP, and GFDevice::disableShaders has not the necessary information to decide the shader to be used.
GFDevice::SetupGenericShaders is used instead of GFDevice::disableShaders.
GFDevice::disableShaders will be deprecated on T3D 4.0
- Modified the glow postFX to now respect the current viewport settings.
- This fixes glow rendering for the Oculus Rift and any other time the
glow rendering should be limited to a region of the back buffer.
