This thread is for the Mirror shader comparisons between different versions based on the base game and EPs.
Please keep this thread and only edit for the latest version based on EP. Preview-check before save.
How to use?
The version was first saved from TS2 the base game one up to the Seasons one, and the versions are listed as summaries.
Just choose the desired versions at the "history" tab after loading the "article" tab page for comparison. (coz there are histories for both the article and talk.)
"==" means identical/equivalent; "=/=" means not identical/equivalent
"EP0" means the base game TS2 version, and the rests are self-explanatory.
EP0 VS EP1:
1. viewerRenderType struct upadte
2. + mirrorColor
EP1 VS EP2/3:
1. + DetermineHardwareSupport()
2. + if ($useSWVertexShaderPath)
3. + if (not varExists(isContentViewer))
EP4/5 VS EP6:
+ BlankMirrorMaterial for kRenderTypePoolReflection & kRenderTypeOceanReflection
Teko's transparent variant is based on the version EP0TS2 by adding alpha-blending.
