Fixes for textures only ground blending mode

Winter not fixed yet seems like there's still some colour blending going on somehow

issue with winter theme, can be fixed by setting the paths to blended: false but it shouldnt be be blending whatever colour this is right?

Hmm, this issue is apparently caused by the material brightness set here, which bleeds into the snow because texture blending is effectively material blending:

  {
    "name": "WINTER_JAGGED_STONE_TILE_LIGHT",
    "parent": "WINTER_JAGGED_STONE_TILE",
    "brightness": 1.825
  },

Arguably it is correct behaviour, and I don't think it can be fixed in code without some crazy hacks, so our best option I think is to fix this by making these tile overrides shift the brightness instead of having the material do it.

This should be fixed now but I cant confirm if it interferes with the original blending mode until the bug which makes blendingTextures effect both ON and TEXTURES, when it should only effect TEXTURES

Heres what it looks like without the extra path I add in:

Heres what it looks like after:

And here are the tiles I think are blending still when they shouldn't be, all the tile_overrides involved have blending: false

I don't think this is an issue specific to the new blending mode, but rather something thats only been noticed now
Either the whole tile is somehow blending with the tiles around it, or the parts in red, idk?
