Bioware TXI Example

#*****************************
# MATERIAL SPECIFIC FIELDS ***
# These fields go in the .txi file for the base texture.
# That is, do not specify these fields in the bumpmap
# or environment map .txi files - they will be ignored.

# Specify a bumpmap
#
# Default is no bumpmap.

bumpmaptexture mybumpmapname

# Specify an environment map for static geometry.
# Dynamic geometry uses the environment map provided on
# the model.
#
# Default is no environment map

envmaptexture myenvmapname

# Specify a blending mode for a material.  This blending
# mode will override the standard mode:
#
# Options are "additive", "punchthrough", "default"
#
# Default is default.

blending default

#****************************
# TEXTURE SPECIFIC FIELDS ***
# These fields are applied to the texture being read in.
# Some are specific to different types of textures (like
# bump maps) and will be ignored if the .txi belongs to
# a texture which is not of the same type.  I will try to
# document these cases.  

# The default width and height of a texture in the
# absence of an image.  These are usually set when you
# are using a procedural texture.
#
# Defaultfor both values is 16

defaultwidth  16
defaultheight 16

# Specify the procedural type.  Only use this if a texture
# needs to be generated procedurally.
#
# Options are "water", "life", "perlin", "arturo" or "wave".
#
# Default is no procedural type.

proceduretype arturo

# Specify how the texture can be downsampled.  
#
# Default is a min of 0, max of 15

downsamplemax 2
downsamplemin 0

# Specify whether or not to mipmap the texture.
#
# Default mipmap is on.

mipmap 0

# Specify whether or not to filter the texture using linear
# filtering or not.  If set to 0, filtering is nearest,
# otherwise it is linear.
#
# Default filtering is linear.

filter 1

# Specify the gamma correction for this filter.
#
# Default gamma correction is 1.0

gamma 0.5

# Specify whether or not this texture is a bumpmap.  If this
# flag is set, the texture module will expect to read in a
# texture which is grayscale.
#
# Default is 0

bumpmap 1

# Specify what kind of bumpmapping this bump map will do:
# specular, diffuse, or both.  These values are ignored if
# this texture is not a bump map.
#
# Default: isdiffusebumpmap 0, isspecularbumpmap 1

isdiffusebumpmap  1
isspecularbumpmap 1

# Specify a scaling factor for the bumpmap height.  If you
# want higher peaks and lower valleys in the bump map, set
# the value to be greater than 1.  If you want a smoother bump
# map, set this value to less than 1.
#
# Default is set to 1.

bumpmapscaling 1.5

# Specify a color for specular bumpmap highlights (RGB).  This
# value is modulated with the bump mapping light's color
# to produce the final highlight color.
#
# Default is (1,1,1)

specularcolor 0.5 0.5 0.8

#***********************************************
# GENERAL TEXTURE CONTROLLER SPECIFIC FIELDS ***
# These fields only apply to those textures
# which are procedural.  If these values are
# specified on a non-procedural texture, they will
# be ignored.

# The following two fields specify how a procedure should be
# applied to create a final texture.  The scaling factor
# indicates how much the channels of the final procedural image
# should be affected by the procedural result.  The translation
# factor indicates how much to add to the scaled results for
# each channel.
#
# Default: Channelscale is all 1's, channeltranslate is all 0's.
# This creates a grayscale semitransparent image based on
# the procedure.

# The following field indicates whether or not to distort an
# image using the procedure.  If this field is set to 1, it requires
# that an image be provided for this texture.  Also, if this value
# is set to 1, all channelscale and channeltranslate values will
# be ignored.
#
# Default is set to 0.

distort 1

# If this value is set to 1, the texture distortion occurs in an
# angular fashion.  If 0, distortion occurs in a linear fashion.
# Both are valid but can produce different distortion effects.
#
# Default is set to 0.
    
distortangle 0

# This value indicates how much the texture should be distorted
# (in texels).  If the value is small, the original image will
# not be distorted significantly.  If it is too large, the
# distortion will generate a very noisy and chaotic result.
#
# Default is set to 5.0

distortionamplitude 3.5

# This value indicates the speed of the procedure.  Most procedures
# can be sped up or slowed down based on this value.
#
# Default is 1.0

speed 2.0

# The following two parameters are used for Arturo procedural textures.  
# The actual arturo function is calculated using the size specified
# in these parameters, and is then upsampled to the size of the texture.
# You may be able to get better results by tinkering with these,
# although the default values work very reasonably.
#
# Default is 15 for both.
