review of per and post bake protocols showed that the CAPTURING shader macro was not being properly recompiled in. as opengl was not playing nice with a simple batch shader recompilation for all effected shaders, a full lightmanager restart is at time of writing required. once we have a proper globally cached scene structure stored off GPU side, we'll want to change GFXShader::addGlobalMacro("CAPTURING", String("1")); on over to dirtying that value in the cached buffer via setting a shader global uniform
review of prefilter examples shows a fixed sample count of 1024 across multiple implementations, so we'll use the standard barring further research into where that number is comming from for a scalar approach
review of gl shaders shows a doubleup in compiled state testing, so slimmed that down and added additional debugging reports
Added support for .hdr format, atm just being converted to ldr after the exposure is applied.
cleanup dds file
PNG skips 16bit altogether at the moment for textureArray issues.
Generating image previews of image assets was failing
DDS remove redundant check for stream status.
STB requires the file to be free before being written to, move check to make sure we can open the path into gBitmap and remove FileStream checks from everywhere else.
two things stuck out as proximal causes for an overdark result on community review
1) $PostFX::HDRPostFX::keyValue was significantly too low given existing calculations, so upped that to 00.5 in keeping with the general assumption were remain intending to have that be the dead center value of a luminance range
2) Fr_DisneyDiffuse input assumptions differ from current engine ones, so reverting that to lambert .
1) fix spotlight shadow casting. we weren't properly accounting for reversedepthbuffer there
2) fix mismatched variables in forward lit spotlight param array
3) use disney diffuse in the generalized brdf, and apply it for spotlights after angular attenuation, not before
4) .provide a generailze luxTargMultiplier approach for spot and point lights (as well as future growth areas) so that range, angle ect can impact the brightness variable sent to a given light source shader without perpixel overhead
5) for spotlightParams in particular, use sizeof(point4f) for the alignedarray untill that's properly reviewed/revised
6) narrow attenuation slightly based on a given lights dot product to prevent tool vs outcome leakage, plus provide safeties for when a given spotslight's inner and outter angles match identially
- Fixes the AB's select button not being properly offset to the right side
- Fixes incorrect height offset for the main editor tabbook because of a no-longer-used variable
- Fixes the bottom of the scene tree scroll being cut off
