Features

Supports 99% of thm parameters

Functionality

Hotkeys

F4 - Open file
F5 or Ctrl+S - Save file
F6 - Save as

Buttons

File Button

Button	Description
Load	Loads the selected .thm
Save	Save .thm
Save As	Save as .thm
Exit	Exit

Tools Button

Button	Description
Import DDS Params	Adjust .thm to the texture format (texture format can be set incorrectly, so sometimes it is worth adjusting it manually)
Generate THM for texture	When you select a basic texture, the program creates a thm with basic properties for it (if a texture with the prefix _bump is found, the thm will set all the necessary flags for using bumps)

MIP Filter

Tip

Different algorithms of MIP-map filtering

Field	Description	Preview
Box	Simplest MIP-map generation algorithm. However, the box filter has a number of limitations that can be quite noticeable with certain textures. For example, if a texture contains very narrow features (e.g., lines), then aliasing artifacts may be very pronounced
Cubic	Generation with weighted sum of eight pixels. The advantage of the cubic filter over the box is that it can have negative side lobes (weights) which help maintain sharpness while reducing the image. This can help reduce some of the blurring effect of filtering with mipmaps
Point	(aka Nearest-neighbor interpolation) Uses only one pixel from the mipmap This is a simple and fast texture filtering method that works well in some cases, but can create visual artifacts and reduce image quality in more complex scenes.
Triangle
Quadratic	This method offers a balance between quality and performance It uses an interpolation method that is based on quadratic equations. Instead of just selecting one pixel (as in Point), this method considers three pixels - one from the selected mipmap level and the two closest to it - to greatly improve the smoothness of the transition of color values.
Advanced
Catrom
Mitchell
Gaussian
Sinc
Bessel
Hanning
Hamming
Blackman
Kaiser	Increase readability of textures by increasing sharpness and contrast

Material

Tip

Different shading algorithms

Field	Description
OrenNayar Blin	`Oren-Nayar shading` is a lighting model used in computer graphics to render matte (rough) surfaces with respect to their micro geometry. `Blinn shading` uses a combination of diffuse and specular light reflection to achieve a more realistic image of shiny objects.
Blinn Phong	`Blinn shading` uses a combination of diffuse and specular light reflection to achieve a more realistic image of shiny objects. `Phong shading` model can achieve good visual results, making objects appear more three-dimensional and realistic, but at the same time it cannot always accurately reproduce lighting effects on more complex or uneven surfaces.
Phong Metal	`Phong shading` model can achieve good visual results, making objects appear more three-dimensional and realistic, but at the same time it cannot always accurately reproduce lighting effects on more complex or uneven surfaces. `Metal shading` is focuses on the realization of materials imitating metallic surfaces.
Metal OrenNayar	`Metal shading` is focuses on the realization of materials imitating metallic surfaces. `Oren-Nayar shading` is a lighting model used in computer graphics to render matte (rough) surfaces with respect to their micro geometry.
