Textures are defined when a 2D image is mapped on a geometry : we use textures on AxF materials, Phong model materials, Oren Nayar model materials, normal maps,...

In Standard Unity shaders, textures cannot be rotated : their rotation is defined by the geometry's UV coordinates. In Predict Engine, if the Expert Mode is enabled, textures can be rotated. The rotation is given in degrees (°). By default, the rotation of all the textures is set to 0°.

If the Expert Mode is enabled, a toggle "Clamp" is also added to the texture definition : it defines whether the texture should be repeated over all the UV coordinates or only used on UV coordinates in [0,1]. By default, the clamp field of all the textures is set to false.

This setting correspond in Unity to the Wrap Mode field that is defined on the Texture inspector, but it can be set differently on each material that reference a texture.
