What Textures Does Stone Knapping Use?

[jun1per]

I'm making a mod that make other stone types knappable into tools, but I noticed the "stone plate" that you knap on lacks textures for some stones. (conglomerate, phyllite, etc) I'm unsure which files dictate the texture used for this object or which textures it draws from. If anyone knows please let me know!

Example of what I'm talking about:

Figured it out! 

There's a block that dictates the knapping surface's texture under "blocktypes/stone/knappingsurface.json". You can patch in whatever textures you need with something like this:

[
	{
		"op": "addmerge",
		"path": "/textures",
		"value": {
			conglomerate: { base: "block/stone/rock/conglomerate1" },
			limestone: { base: "block/stone/rock/limestone1" },
			phyllite: { base: "block/stone/rock/phyllite1" },
			slate: { base: "block/stone/rock/slate1" },
			kimberlite: { base: "block/stone/rock/kimberlite1" },
			scoria: { base: "block/stone/rock/scoria1" },
			tuff: { base: "block/stone/rock/tuff1" },
			bauxite: { base: "block/stone/rock/bauxite1" },
			halite: { base: "block/stone/rock/halite1" },
			suevite: { base: "block/stone/rock/suevite1" },
			whitemarble: { base: "block/stone/rock/whitemarble1" },
			redmarble: { base: "block/stone/rock/redmarble1" },
			greenmarble: { base: "block/stone/rock/greenmarble1" },
			travertine: { base: "block/stone/rock/travertine1" },
			coralchunk-dead: { base: "block/creature/aquatic/coral/sponge/dead2" },
		},
		"file": "game:blocktypes/stone/knappingsurface.json",
	}
]

Hope this helps anyone else who runs into this problem!
