HardTop Vanillaccurate Pack v0.1.4

Here is a new WIP version of Vanillaccurate Pack. Enjoy !

• added SSS to obsidian (test required? needs alpha?)
• fixed ice transparency
• reworked most blocks to account for non-null metallic value (see below)
• checked/adjusted porosity on some blocks.
• reworked some blocks to use proc-genned textures:
  • Going further down the rabbit hole with proc-genned details, I changed some blocks to replace the photographic textures with proc-genned textures.
    • Blocks changed in this version: bricks, iron block, gold block, sand

NOTICE: I also adjusted Continuum format after a realization I had by checking the shader code. When using SEUS (or possibly LabPBR with some inaccuracies for metal) format the F0 term is computer from the green channel. I noticed there is a function which forces the metalness to 0.02 for non-metals (0 in the green channel). Continuum format doesn’t perform that calculation and basically takes the value in the red channel as raw F0 term. What this implies is that a very small fresnel 0 term is required in Continuum for reflections to occur. If F0 term is flat 0, reflections won’t be applied thus a small, non-zero value is required (which is consistent with how dielectrics behave in nature, they have a very small, non-zero value). I changed the converter so the Continuum format is correct.

That’s also a reminder to me that I need to adjust the F0 values for dielectrics, as they’ve been 0 up to now. As they need to be small but non-zero (as per LabPBR specification), I started reworking the already designed blocks to adjust that value so shaders relying on that will behave as they should. It’s a WIP so it’ll probably take a couple of versions to include all blocks.

Just FYI: this document explains how dielectrics behave, stating that most dielectrics have a F0 term between 2 and 5%, explaining the value of 0.02 Continuum uses.
