# Template Override

Override a single template property of VRay Materials with a new value.

### **Property Name**

Name of the property to replace

Must start with `TK_` and must be an existing property in a template material

### **Property Type**

`Map`, `Color`, or `Number`

### **Map**

Texture asset used to replace the original map value

Only available if the property type is set to `Map`

### **Color**

Color value used to replace the original color value

Only available if the property type is set to `Color`

### **Number**

Number value used to replace the original number value

Only available if the property type is set to `Number`

### Limitations

* Can only be applied on an imported VRay material
* If the wrong **Property type** is selected, based on the original type of the property in the template material, it's undefined behavior
* The number value doesn't have any validation or limits, this might cause undefined behavior depending on the role of the `TK_` property in the material definition
