### Advanced texture modifiers
-#### `[crack:<n>:<p>`
+#### Crack
+* `[crack:<n>:<p>`
+* `[cracko:<n>:<p>`
+* `[crack:<t>:<n>:<p>`
+* `[cracko:<t>:<n>:<p>`
+
+Parameters:
+* `<t>` = tile count (in each direction)
* `<n>` = animation frame count
* `<p>` = current animation frame
Draw a step of the crack animation on the texture.
+`crack` draws it normally, while `cracko` lays it over, keeping transparent pixels intact.
Example:
* `"image.png"`
* `{name="image.png", animation={Tile Animation definition}}`
* `{name="image.png", backface_culling=bool, tileable_vertical=bool,
- tileable_horizontal=bool}`
+ tileable_horizontal=bool, align_style="node"/"world"/"user", scale=int}`
* backface culling enabled by default for most nodes
* tileable flags are info for shaders, how they should treat texture
when displacement mapping is used
Directions are from the point of view of the tile texture,
not the node it's on
+ * align style determines whether the texture will be rotated with the node
+ or kept aligned with its surroundings. "user" means that client
+ setting will be used, similar to `glasslike_framed_optional`.
+ Note: supported by solid nodes and nodeboxes only.
+ * scale is used to make texture span several (exactly `scale`) nodes,
+ instead of just one, in each direction. Works for world-aligned
+ textures only.
+ Note that as the effect is applied on per-mapblock basis, `16` should
+ be equally divisible by `scale` or you may get wrong results.
* `{name="image.png", color=ColorSpec}`
* the texture's color will be multiplied with this color.
* the tile's color overrides the owning node's color in all cases.
