# Textures

### Textures - Common

**Apply Texture**
Apply the given texture to the specified object

**Get Texture**
Returns the selected texture from the dropdown list

**Texture**
Apply the given texture to the specified object

**Texture Part ID**
Returns the ID of the specified object's texture type

### Textures - Get Operations

**Get Class Texture**
Return a texture given a class name

**Get Class Use Texture**
Returns whether the classes' texture attributes will be used at object creation

**Get Image Cropper**
Returns the crop of a cropped image

**Get Shader Record**
Returns the shader record of the specified family, if one is attached to the texture

**Get TexBmp**
Returns the bitmap object attached to the referenced shader record. If there is no texture applied to an object, the function returns nothing

**Get TexBmp Property**
Returns the properties of the referenced texture bitmap

**Get Texture Layer Count**
Returns number of texture layers (base + decals) for the specified part of an object

**Get Texture Map**
Get map info for a specific part of an object

**Get Texture Reference**
Returns the texture reference of a specified object

**Get Texture Set**
Returns the texture set of an object

**Get Texture Shader**
Returns the LightWorks internal property reference ID for the shader attached to the referenced texture

**Get Texture Shininess**
Returns the shininess value of the referenced texture

**Get Texture Size**
Returns the texture size in real-world inches

**Get Texture Space**
Returns a handle to the texture space attached to the referenced object (or object part). Note: Walls may have three texture spaces attached to them if they have expanded textures

**Get Transparency**
Returns the degree of transparency applied to the referenced texture
