How to Export from ZBrush?

Understanding the Export Process from ZBrush

Exporting models from ZBrush is crucial for integrating your work into various digital environments, including 3D applications and game engines. This guide provides a detailed overview of the steps needed to export your work effectively using different formats.

Exporting to OBJ Format

1. Selecting the Tool: Start by selecting the tool you want to export. Ensure that your desired model is active in the ZBrush workspace.

2. Geometry Settings: Navigate to the “Tool” palette and select “Geometry.” Adjust the SDiv to 1. This setting indicates you’re working with the lowest subdivision level, ensuring a manageable export size.

3. Saving the Mesh: To export, go to the “File” menu and select “Export.” Choose the OBJ file format, naming it appropriately and choosing a location on your computer.

4. Open in Other Programs: After exporting, you can import the OBJ file into various 3D applications like Maya or Blender. In the target application, use the import function to bring your model into the scene.

Exporting to FBX Format

1. FBX Export Plugin: Make sure you have the FBX Export Import plugin installed in ZBrush. This plugin facilitates a smooth workflow between applications.

2. Select Tool and Subdivisions: Just like exporting to OBJ, select your tool and ensure you’re at the appropriate subdivision level.

3. Exporting as FBX: Go to “File” → “Export.” Choose FBX as your file type, and save it in your desired location on your system.

4. Import in Target Software: Open the application you plan to use and navigate to the import feature. Select FBX as your format and load the exported file.

Exporting from ZBrush to Maya

1. Prepare the Model: Ensure that the model is finished and that all details are set to your liking.

2. Convert to OBJ: As noted previously, export your model in OBJ format.

3. Importing in Maya: Open Maya, navigate to “File” → “Import,” select OBJ, and choose your exported file. Make the necessary adjustments to your UV layouts as required.

Exporting from ZBrush to Blender

1. Export Model: Similar to the previous steps, export your model as an OBJ file from ZBrush.

2. Loading into Blender: Launch Blender, and go to “File” → “Import” → “Wavefront (.obj).” Make sure to enable “Image Search” to properly import any textures associated with the model.

Supported Export Formats by ZBrush

ZBrush supports various formats for exporting models, ensuring compatibility with multiple platforms. Some key formats include:

1. Wavefront OBJ – A common format, suited for detailed models.
2. Maya (.ma) – Native Maya format for seamless integration.
3. FBX – Ideal for animations and more complex data.
4. STL – Utilized primarily for 3D printing.
5. GoZ – For programs supporting GoZ functionality, allowing for direct transfer.
6. 3D Print Formats – Additional capabilities for 3D printing applications.

Exporting Low Poly Models

1. Initial High Poly Model: Start by modeling your character in a T-pose with high detail.

2. Retopology Process: Use the ZRemesher tool to create a low poly version of your model, which is optimized for use in real-time applications.

3. IIntegration with Other Applications: After retopology, export the low poly model as needed, ensuring you also bake details from the high poly mesh like normal maps and displacement maps for textures.

Frequently Asked Questions

1. Can I export animations from ZBrush?
   ZBrush is primarily a sculpting tool and does not support animation export directly. However, you can create UV maps and texture details on your models, which can then be animated in other applications.

2. What should I do if my exported model looks different in another application?
   Ensure that your export settings are correct, especially concerning the model’s scale, materials, and UV settings. It’s advisable to verify UVs and textures in your target application.

3. Is it possible to transfer my settings between ZBrush and other software?
   Direct transfer of settings is not supported. However, using file formats like FBX and OBJ helps ensure that the geometry and materials are retained for use in compatible software. Always check the documentation for specifics on transferring data.
