SET OBJECT TEXTURE
This command will set different texture modes used by the specified object. Every texture is painted onto an object using an internal set of values called UV data. This data contains a range of real numbers from zero to one. Zero specifying the top/left corner of your texture and one being the bottom/right corner of your texture. When an object uses UV data greater and less than this range, you are permitted a number of texture wrap modes to describe what should happen to paint these areas. Setting the Texture Wrap Mode to zero will use the default wrap mode which repeat the pattern of the texture over and over, a mode of one will mirror the texture to create a seamless texture pattern and a mode of two will set clamping which retains the colour of the last pixel at the textures edge and paint with that throughout the out of range area. The Mipmap Generation Flag is used to ensure the image has a mipmap texture. A mipmap is a texture that has many levels of detail, which the object can select and use based on the objects distance from the camera. Use integer values to specify the parameters.

or
TEXTURE OBJECT
This command will texture an object using the specified image. The image can be any size, but the quality of the texture depends on the graphics card used. A texture size to the power of two is recommended size for all your textures. Where an image is larger than the supported texture size, the image is internally reduced when used as a texture. The object and image number must be integer values. You can use this command to remove the effects of multitexturing effects and shaders. An additional texture stage index can be provided to the command to specify multi-textures directly, and is required when using shaders that take pixel data from secondary textures.

or
TEXTURE LIMB
This command will apply an existing image to the limb of a 3D object as a texture. You must create an image first using the GET IMAGE command before attempting to texture part of the 3D object. The parameters should be specified using integer values. An additional texture stage index can be provided to the command to specify multi-textures directly, and is required when using shaders that take pixel data from secondary textures.
