# Re-linking File Process Introduction

If you change the path or name of the model file, you can update the D5 project using the re-linking function, ensuring that previous lighting and material settings are preserved. This process is compatible with **SU/SketchUp** and **3dsMax** real-time plug-ins.

  * Data synchronisation after model renaming/path changes

  * Avoid duplicate light overlays

  * Preserve historical material parameters

  * Inheritance of model attributes

## Workflow

### Method 1: Models linked to .drs before

**Scenario:** The model has been linked to a D5 project, but the local storage path or name has been altered.

#### **Operating Steps:**

**Activate Connection**

  1. Click the ‘Connect to D5 Render’ button in the DCC plug-in.

  2. Select the ‘Sync local Project’ mode in the pop-up window.

Step 1

**Select the model to replace**

Tick the target model to be replaced in the popup window. (D5 materials will be inherited after replacement)

Step 2

Click ‘Replace and link’ to complete the synchronisation.

### Method 2: Open .drs and the modeling file together

**Scenario:** need to update both the model file and the associated project at the same time

#### **Workflow:**

  1. Open the D5 project file (.drs) and the modified model file at the same time.

  2. Click the ‘Connect to D5 Render’ button in the DCC plug-in.

Step 1

  1. Select the corresponding model in the Replacement pop-up window.

  2. Tick the ‘’Light‘’ / ‘’Material‘’ options as required.

  3. Click ‘Replace and link’ to complete the synchronisation.

Replace and link logic

### Option Description:

  * Tick ‘’Light‘’: Replace the light group with the same ID (historical parameters are preserved)

  * Tick ‘Material’: Replace materials with same names (historical parameters are preserved).

**Note:**

  * ‘’Light‘’ replacement only supports SU/3dsMax LiveSync plug-ins.

  * No light/material ticking options for non-real-time plug-ins and direct imported models.

## FAQs

### Q1: Why does the DCC prompts "Please retry after exit rendering mode or finish the rendering within D5 Render"?

A：

The general situation is: after entering the picture/video mode in D5, and then performing the increase or decrease model operation in DCC and transmitting new data (real-time update or manual update) to D5, this error will occur.

In this case, exit the picture/video mode, and then re-associate the synchronization.
