-This file describes how to use CTM, structure of `.properties` file and some useful (or not) techniques
-
-### Note:
-- All textures for CTM textures are in `[modname]/mcpatcher/ctm` folder<br>
-the overrides apply globally so it doesn't matter in which directory you put them<br>
-
-- in the `ctm` folder you must have a folder with your block name (or any name actually)<br>
-in that folder you will have all texture files (animations allowed via mcmeta file for every texture) and `.properties` file<br>
-multiple `.properties` files are allowed for a single folder and set of textures for more complex behaviour (see examples)

-## Structure of `.properties` files
-
----
-
-## `matchBlocks`
-Override for a specific block, you can get the value from the tooltip if you have this feature enabled.<br>
-Can accept several values which allows to apply one CTM for different blocks.<br>
-if no value for this property was provided, Angelica will fallback to name of the `.property` file
-
-examples:<br>
-`matchBlocks=gregtech:gt.blockcasings4`<br>
-`matchBlocks=minecraft:glass minecraft:glass_pane`
-
----
-
-## `matchTiles`
-Override for a specific texture, main difference from matchBlocks is that this will only match a certain texture, not the block itself<br>
-
-example:<br>
-`matchTiles:minecraft:blocks/stone`
-
----
-
-## `tiles`
-The list of texture names for CTM. Supports ranges and explicit names.<br>
-You probably would want to use texture names like `0.png`, `1.png` as it is easier, however this allows for any names
-
-examples:<br>
-`tiles=0-46` - classic for full CTM, expects files from `0.png` to `46.png`<br>
-`tiles=0-3,5, 8` - expects files `0.png`, `1.png`, `2.png`, `3.png`, `5.png`, `8.png`<br>
-`tiles=sometext,somemoretext` - expects files `sometext.png`, `somemoretext.png`
-
----
-
-## `connect`
-Sets how the blocks are connected, can accept values: `block`, `tile`, `material`<br>
-`block` connects based on block (who would guess)<br>
-`tile` connects based on texture<br>
-`material` connects based on material (didn't really understand this part, ig it is for stone, iron, wood etc)<br>
-Fallbacks to `block` if no value for `matchTiles` is set, otherwise fallbacks to `tile`<br>
-Most of the time you don't need to set this value because of that fallback rule
-
-example:<br>
-`connect=block`
-
----
-
-## `faces`
-Limit to specific faces of a block, can accept several values<br>
-Fallbacks to `all` if value not present in the `.properties` file
-
-examples:<br>
-`faces=top`<br>
-`faces=all`<br>
-`faces=bottom`<br>
-`faces=sides`<br>
-`faces=north south east west`<br>
-`faces=top bottom sides`
-
----
-
-## `biomes`
-Limit to specific biomes, can accept several values<br>
-Fallbacks to all if value not present in the `.properties` file
-
-examples:<br>
-`biomes=plains`<br>
-`biomes=desert forest`<br>
-`biomes=taiga jungle savanna`
-
----
-
-## `heights`
-Limit to certain Y levels, can only accept several values<br>
-can be set through either `minHeight` and `maxHeight` or `heights`
-
-examples:<br>
-`heights=0-64`<br>
-`heights=64-255`<br>
-example of maxHeight and minHeight:<br>
-`minHeight=64`<br>
-`maxHeight=128`
-
----
-
-## `renderPass`
-Controls which rendering layer a CTM rule is applied in<br>
-In most cases you only need it to avoid rendering issues with transparency
-
-`renderPass=solid` used for fully opaque blocks<br>
-`renderPass=cutout` used for fences, glass CTM, textured blocks with hard transparency<br>
-`renderPass=translucent` used for transparent blocks like glass or water<br>
-`renderPass=cutout_mipped` no idea for what<br>
-`renderPass=overlay` used for blocks with an overlay, for example GT hatches or damaged anvils<br>
-`renderPass=backface` used for blocks with a backface, however it is very rare to use this one
-
----
-
-## `innerSeams`
-Adds internal seams, fallback to `innerSeams=false` if not set<br>
-
-example:<br>
-`innerSeams=true`
-
----
-
-## `weights`
-Priority, used for `Random` type to determine which textures have certain chances to be used for render<br>
-accepts several values, assigns values correspondingly to `tiles` list values
-
-examples:<br>
-`weight=10`<br>
-`weights=1 3 3 2 1`
-

-# `Method`
-
-Selects CTM mode:
-- [LINK](#full-ctm-ctm) `ctm` / `glass` / `default`
-- [LINK](#compact-ctm) `compact` / `ctm_compact`
-- [LINK](#horizontal)`horizontal` / `bookshelf`
-- [LINK](#vertical)`vertical`
-- [LINK](#horizontalvertical-hv)`horizontal+vertical` / `h+v`
-- [LINK](#verticalhorizontal-vh)`vertical+horizontal` / `v+h`
-- [LINK](#top)`top` / `sandstone`
-- [LINK](#repeat)`repeat` / `pattern`
-- [LINK](#random)`random`
-- [LINK](#fixed)`fixed` / `static`
-
-example:<br>
-`method=ctm`
-
-### Full CTM (ctm)
-
-Requires exactly 47 tiles, the most versatile but the most size-heavy method
-
-Here's a visual explanation of how the textures should be numbered:
-
-<img src="img/CTM/CTM-pattern.png" width="624" style="image-rendering: pixelated;">
-
----
-
-### Compact CTM
-
-Requires exactly 5 tiles.
-
-<img src="img/CTM/CCTM-pattern.png" width="284" style="image-rendering: pixelated;">
-
-Splits face into 4 quadrants and builds final texture per quadrant.
-
-Here's a visual explanation of how it works on an example of 3x3 blocks pattern with a cutout:
-
-<img src="img/CTM/CCTM-principle.png" width="400" style="image-rendering: pixelated;">
-
-as you can see, compact CTM has a single limitation:<br>
-the size of any part of texture, such as an edge or a corner, can't be larger than `8x8` pixel<br>
-this is the main case where only full CTM can be used.
-
----
-
-### Horizontal
-
-Requires exactly 4 tiles. connects only horizontally, used for bookshelves for example
-
-<img src="img/CTM/HCTM-pattern.png" width="284" style="image-rendering: pixelated;">
-
-
----
-
-### Vertical
-
-Requires exactly 4 tiles.
-
-<img src="img/CTM/VCTM-pattern.png" height="284" style="image-rendering: pixelated;">
-
----
-
-### Horizontal+Vertical (h+v)
-
-Requires exactly 7 tiles.
-
-Two-stage: horizontal first, then vertical if none horizontal variations are found.
-
-<img src="img/CTM/HVCTM-pattern.png" height="284" style="image-rendering: pixelated;">
-
----
-
-### Vertical+Horizontal (v+h)
-
-Requires exactly 7 tiles.
-
-Two-stage: vertical first, then horizontal if none vertical variations are found.
-
-<img src="img/CTM/VHCTM-pattern.png" height="284" style="image-rendering: pixelated;">
-
----
-
-### Top
-
-Requires exactly 1 tile.
-
-Applies tile on side faces when block above matches, for example used for smooth sandstone
-
----
-
-### Repeat
-
-Requires width * height tiles.
-
-Properties:
-- `width` - defines the number of tiles in width
-- `height` - defines the number of tiles in height
-- `symmetry` - defines the symmetry of the pattern, can be either `none` or `opposite`
-
-Just uses N*M grid, for example<br>
-`0 1 2 3 4`<br>
-`5 6 7 8 9`
-
----
-
-### Random
-
-Any number of tiles.
-
-Properties:
-- `weights` - described [here](#weights)
-- `symmetry` - accepts `all`, `opposite`, `none`, groups opposite faces together, otherwise keeps them independent
-- `linked` - makes the textures consistent between render states, not needed much
-
----
-
-### Fixed
-
-Requires exactly 1 tile. Always uses the same tile.<br>
-useful only if combined with height or other properties (see examples)
-
----
-
-# Examples
-
-## Glass via full CTM
-```properties
-matchBlocks=minecraft:glass minecraft:glass_pane
-metadata=0
-method=ctm
-faces=all
-tiles=0-46
-connect=block
-```
-
-## Multiple properties files usage
-### Use multiple .properties files with different heights for more detailed worldgen
-this one will use one texture for lower part of the world and another for the rest of the world
-```properties
-matchBlocks=minecraft:dirt
-metadata=0
-method=fixed
-faces=all
-tiles=0
-connect=block
-maxHeight=40
-```
-
-```properties
-matchBlocks=minecraft:dirt
-metadata=0
-method=fixed
-faces=all
-tiles=0
-connect=block
-minHeight=41
