# Comments directly above a setting are bound to this setting.
# All other comments are ignored.

# Comments and (Readable name) are handled by gettext.
# Comments should be complete sentences that describe the setting and possibly
#  give the user additional useful insight.
# Sections are marked by a single line in the format: [Section Name]
# Sub-section are marked by adding * in front of the section name: [*Sub-section]
# Sub-sub-sections have two * etc.
# There shouldn't be too much settings per category; settings that shouldn't be
#  modified by the "average user" should be in (sub-)categories called "Advanced".

[Graphics]

[*In-Game]

[**Basic]

#    Enable VBO
enable_vbo (VBO) bool true

#    Whether to fog out the end of the visible area.
enable_fog (Fog) bool true

#    Leaves style:
#    -   Fancy:  all faces visible
#    -   Simple: only outer faces, if defined special_tiles are used
#    -   Opaque: disable transparency
leaves_style (Leaves style) enum fancy fancy,simple,opaque

#    Connects glass if supported by node.
connected_glass (Connect glass) bool false

#    Enable smooth lighting with simple ambient occlusion.
#    Disable for speed or for different looks.
smooth_lighting (Smooth lighting) bool true

#    Clouds are a client side effect.
enable_clouds (Clouds) bool true

#    Use 3D cloud look instead of flat.
enable_3d_clouds (3D clouds) bool true

#    Method used to highlight selected object.
node_highlighting (Node highlighting) enum box box,halo,none

#    Adds particles when digging a node.

#    Use anisotropic filtering when viewing at textures from an angle.
anisotropic_filter (Anisotropic filtering) bool false

#    Use bilinear filtering when scaling textures.
bilinear_filter (Bilinear filtering) bool false

#    Use trilinear filtering when scaling textures.
trilinear_filter (Trilinear filtering) bool false

#    Filtered textures can blend RGB values with fully-transparent neighbors,
#    which PNG optimizers usually discard, sometimes resulting in a dark or
#    light edge to transparent textures.  Apply this filter to clean that up
#    at texture load time.
texture_clean_transparent (Clean transparent textures) bool false

#    When using bilinear/trilinear/anisotropic filters, low-resolution textures
#    can be blurred, so automatically upscale them with nearest-neighbor
#    interpolation to preserve crisp pixels.  This sets the minimum texture size
#    for the upscaled textures; higher values look sharper, but require more
#    memory.  Powers of 2 are recommended.  Setting this higher than 1 may not
#    have a visible effect unless bilinear/trilinear/anisotropic filtering is
#    enabled.
texture_min_size (Minimum texture size for filters) int 64

#    Experimental option, might cause visible spaces between blocks
#    when set to higher number than 0.

#    It should give significant performance boost at the cost of less detailed image.

#    Enables on the fly normalmap generation (Emboss effect).
#    Requires bumpmapping to be enabled.
generate_normalmaps (Generate normalmaps) bool false

normalmaps_strength (Normalmaps strength) float 0.6

#    Defines sampling step of texture.
#    A higher value results in smoother normal maps.

[***Parallax Occlusion]

#    Enables parallax occlusion mapping.
#    Requires shaders to be enabled.
enable_parallax_occlusion (Parallax occlusion) bool false

#    0 = parallax occlusion with slope information (faster).
#    1 = relief mapping (slower, more accurate).
parallax_occlusion_mode (Parallax occlusion mode) int 1 0 1

#    Strength of parallax.
3d_paralax_strength (Parallax occlusion strength) float 0.025

water_wave_height (Waving water height) float 1.0

water_wave_length (Waving water length) float 20.0

water_wave_speed (Waving water speed) float 5.0

#    Set to true enables waving leaves.
#    Requires shaders to be enabled.
enable_waving_leaves (Waving leaves) bool false

#    Set to true enables waving plants.
#    Requires shaders to be enabled.
enable_waving_plants (Waving plants) bool false

[*Mapgen Valleys]

#    Map generation attributes specific to Mapgen Valleys.
#    'altitude_chill' makes higher elevations colder, which may cause biome issues.
#    'humid_rivers' modifies the humidity around rivers and in areas where water would tend to pool,
#    it may interfere with delicately adjusted biomes.
#    Flags that are not specified in the flag string are not modified from the default.
#    Flags starting with 'no' are used to explicitly disable them.
