## 1 Edit Texture

ModelFun includes built-in texture editing tools, accessible directly in the OBJ view. Draw an area and edit texture using editing tools. The modified textures are instantly displayed in the OBJ view.

**Selection Methods**

* **Rectangle** – Draw a rectangular selection area.
* **Lasso** – Draw a freeform selection.
* **Polygon** – Draw a polygonal selection area.

**Editing Tools**

* **Fix Patch** – Define an area to be patched and drag the selected texture to cover it.

## 2 Link to Photoshop

**1) Select Area** – In the OBJ view, draw a selection box around the area that needs editing. The software captures the texture of the selected area based on the current view.

## 3 Unwrap UV

For complex and detailed models with occlusion issues, you can unwrap the UV of the selected area and edit it in Photoshop.

**1) Select Area** – In the OBJ view, draw a selection box around the area that needs UV unwrapping. The software generates the unwrapped texture map based on the selected area.

**2) Auto-Link to Photoshop** – The unwrapped texture automatically opens in Photoshop for detailed editing.

**3) Save & Apply** – After editing, save the file, and the changes will instantly update in the OBJ view.

## 4 AT Mapping

To use the AT Mapping feature, you need set the AT file first. Open the **Project > Setting** option, click **AT Setting**, select the AT file path and photo path, then click **OK** after setup.

## 5 Adjust Color

**1) Generate Color Mask** – Open the model in **Get3D Viewer**, adjust color, and export the color balancing parameter file as **\*.blender**.

**2) Load in Get3D ModelFun** – Import the Get3D Viewer color file into **ModelFun**, set the output format and save path.

**3) Select Tiles** - Manually or automatically select the tiles to be exported.

* **Modified**: Selecting all edited tiles.
* **Select All**: Selecing all tiles.
* **Invert**: Invert the selection of selected tiles.
* **Remove:** Remove the selection

**4) Apply task** – Click **Apply** to export models. Click **Task** to see the stautus of processing. If tasks failed, click **Retry** to export again.&#x20;
