Exporting Textures: Set up texture export presets for Unreal Engine compatibility (size, format, channels)
Exporting textures from Substance Painter to Unreal Engine requires precision to ensure compatibility and optimal performance. Unreal Engine has specific requirements for texture size, format, and channel usage, which must be meticulously configured in Substance Painter’s export presets. Ignoring these details can lead to artifacts, performance issues, or broken materials in your game or application.
Begin by setting up export presets tailored to Unreal Engine’s standards. For texture size, adhere to power-of-two dimensions (e.g., 512x512, 1024x1024, 2048x2048) to avoid distortion or scaling issues. Unreal Engine supports non-power-of-two textures, but power-of-two remains the safest choice for compatibility across platforms. Use the File > Export Textures menu in Substance Painter to create a preset, and under Size, ensure the dimensions match your project’s needs while staying within Unreal’s recommended limits.
Next, focus on texture format and channels. Unreal Engine primarily uses TGA or PNG for source textures, but DDS is preferred for runtime efficiency due to its compression capabilities. In Substance Painter, set the format to PNG for source files and DDS for engine-ready assets. For channels, ensure your presets align with Unreal’s material system. For example, export Base Color in the RGB channels, Metallic in the R channel, Roughness in the G channel, and Normal maps in the default RGB format. Substance Painter’s Channels tab allows you to assign specific data to each channel, ensuring seamless integration with Unreal’s shader models.
A critical step often overlooked is configuring the Normal Map export. Unreal Engine expects normal maps to be in the OpenGL format, not DirectX. In Substance Painter, navigate to the Normal map settings and set the Normal Map Format to OpenGL. Failure to do this will result in inverted normals in Unreal, causing lighting inconsistencies. Additionally, enable Mip Maps during export to improve performance, especially for distant objects.
Finally, test your presets by exporting a sample texture set and importing it into Unreal Engine. Verify that the textures appear correctly in the material editor and that there are no discrepancies in lighting or surface properties. If issues arise, revisit your presets and adjust size, format, or channel assignments accordingly. By investing time in setting up accurate export presets, you streamline your workflow and ensure a smooth transition from Substance Painter to Unreal Engine.

Material Setup: Create Unreal-ready materials using Substance Painter’s Unreal Engine export template
Substance Painter’s Unreal Engine export template is a game-changer for artists looking to streamline their workflow. By leveraging this tool, you can create materials that are not only visually stunning but also optimized for Unreal Engine’s rendering capabilities. The key lies in understanding how to map Substance Painter’s texture sets to Unreal’s material parameters, ensuring seamless integration without manual adjustments. This process begins with selecting the Unreal Engine export preset in Substance Painter, which automatically configures texture formats, sizes, and naming conventions to align with Unreal’s expectations.
Once the export preset is set, the next step is to organize your texture maps effectively. Unreal Engine relies on specific maps like Base Color, Normal, Roughness, and Metallic, which correspond directly to Substance Painter’s outputs. Ensure these maps are correctly assigned in the export settings to avoid mismatches. For instance, Substance Painter’s "Base Color" should map to Unreal’s "Base Color," and "Glossiness" should be inverted and exported as "Roughness." This attention to detail prevents errors and saves time during material setup in Unreal.
A critical aspect of this workflow is understanding Unreal’s material nodes and how they interact with Substance Painter’s textures. In Unreal, create a new material and use the "Material Function" or "Material Graph" to connect the imported textures to their respective nodes. For example, plug the Base Color map into the Base Color node, the Normal map into the Normal node, and adjust the Roughness and Metallic values using their dedicated nodes. This step-by-step approach ensures your material behaves as expected in Unreal’s lighting and shading systems.
While the export template simplifies the process, there are nuances to consider. For instance, Unreal Engine’s sRGB color space requires that Base Color and other non-linear textures be marked as sRGB in the material settings. Failure to do so can result in color inaccuracies. Additionally, if your project uses Substance Painter’s "Height" map for parallax occlusion in Unreal, ensure it’s correctly configured in the material’s "World Position Offset" node. These small but significant adjustments bridge the gap between Substance Painter’s artistic freedom and Unreal’s technical requirements.
Finally, test your materials in Unreal’s real-time environment to ensure they perform as intended. Use dynamic lighting, shadows, and reflections to evaluate how the textures respond. If adjustments are needed, return to Substance Painter, tweak the textures, and re-export using the Unreal preset. This iterative process ensures your materials not only look great but also function optimally within Unreal Engine’s framework. By mastering this workflow, you’ll save time, reduce errors, and achieve professional-grade results.

Importing Assets: Import painted assets into Unreal Engine via drag-and-drop or content browser
Once your assets are meticulously painted in Substance Painter, the next crucial step is seamlessly integrating them into Unreal Engine. This process, surprisingly straightforward, hinges on two primary methods: drag-and-drop and the content browser. Both approaches offer distinct advantages, catering to different workflows and project needs.
Drag-and-drop, the more intuitive option, allows for immediate gratification. Simply locate your exported textures from Substance Painter, select the desired files (albedo, normal, roughness, etc.), and drag them directly into the Unreal Engine viewport or the content browser panel. This method excels in its speed and simplicity, ideal for quick iterations and testing. However, it lacks the organizational structure provided by the content browser.
The content browser, a powerhouse of asset management, offers a more structured approach. Here, you create dedicated folders within your project, mirroring your Substance Painter organization for clarity. Right-click within the desired folder, select "Import," and navigate to your exported textures. This method ensures a clean and organized project structure, crucial for larger teams and complex projects. While slightly more involved, it fosters long-term efficiency and maintainability.
A key consideration is the file format. Unreal Engine supports various texture formats, but PNG and TGA are widely recommended for their balance of quality and performance. Remember to maintain consistent naming conventions across both Substance Painter and Unreal Engine to avoid confusion and streamline material assignments.
Regardless of the chosen method, ensure your textures are correctly assigned to materials within Unreal Engine. This involves creating or selecting an existing material, connecting the imported textures to the appropriate material nodes (base color, normal, roughness, etc.), and adjusting parameters as needed. This final step breathes life into your painted assets, transforming them from static images into interactive elements within your Unreal Engine scene.

Normal Map Adjustments: Ensure normal maps align with Unreal’s coordinate system for accurate lighting
Normal maps are critical for conveying surface detail in Unreal Engine, but their effectiveness hinges on alignment with Unreal’s coordinate system. Unreal Engine expects normal maps to use a Y-up coordinate system, whereas Substance Painter defaults to a Z-up configuration. This mismatch can lead to distorted lighting, where shadows fall incorrectly or surface details appear flattened. To avoid this, always ensure your normal maps are exported from Substance Painter with the correct axis orientation.
Steps to Align Normal Maps:
- In Substance Painter: Before exporting, navigate to the export settings and locate the "Normal Map" options. Enable the "Y-Up" setting to match Unreal’s coordinate system. This ensures the green channel (Y) represents the "up" direction, aligning with Unreal’s expectations.
- Post-Export Adjustment: If you’ve already exported a normal map without the Y-Up setting, use a tool like Photoshop or Substance Designer to manually flip the green and blue channels. This swaps the Y and Z axes, correcting the orientation for Unreal.
Cautions: Avoid relying on Unreal’s automatic normal map conversion, as it may not always produce accurate results. Manual alignment in Substance Painter or during export is more reliable. Additionally, be mindful of texture resolution; high-resolution normal maps can introduce noise or artifacts if not properly optimized.
Practical Tip: Test your normal maps in a simple Unreal scene with directional lighting to verify alignment. Look for consistent shadows and highlights across surfaces. If details appear inverted or stretched, revisit your export settings or channel adjustments.
By meticulously aligning normal maps with Unreal’s coordinate system, you ensure that lighting interacts realistically with your materials, enhancing the visual fidelity of your projects. This small but crucial step bridges the gap between Substance Painter and Unreal Engine, allowing your textures to perform as intended.

UDIM Workflow: Use UDIM tiling in Substance Painter for high-resolution textures in Unreal Engine
UDIM tiling in Substance Painter allows artists to create high-resolution textures without hitting memory limits or sacrificing detail. By dividing a model into multiple UV tiles (UDIMs), each tile can be textured independently at full resolution, then seamlessly combined in Unreal Engine. This workflow is essential for projects requiring intricate details, such as character skins, complex props, or large environments.
To implement this workflow, start by setting up your model with UDIMs in your 3D modeling software. Ensure each tile adheres to the standard UDIM naming convention (1001, 1002, etc.). Import the model into Substance Painter, where the software automatically recognizes and organizes the UDIM tiles. Work on each tile as a separate texture sheet, leveraging Painter’s tools to maintain consistency across tiles, such as shared materials or smart masks. Export the textures using the "UDIM" preset, which generates individual texture files for each tile, ready for Unreal Engine.
In Unreal Engine, import the textures and apply them to your model using the "UDIM" option in the material editor. Unreal automatically stitches the tiles together based on the UDIM naming, creating a seamless high-resolution texture map. Optimize performance by using texture streaming or mipmaps, especially for large environments. For characters, consider using virtual texturing for even greater efficiency, though this requires additional setup.
One caution: UDIM workflows demand careful UV layout planning. Overlapping or misaligned seams between tiles can cause visible artifacts. Always test the model in Unreal Engine after initial texturing to catch and correct these issues early. Additionally, while UDIMs excel at detail, they increase file size and render overhead, so balance resolution with performance needs.
By mastering UDIM tiling in Substance Painter and Unreal Engine, artists can achieve photorealistic textures without compromising workflow efficiency. This technique is particularly valuable for AAA games, film, or any project where texture fidelity is paramount. With proper planning and optimization, UDIMs unlock a new level of visual fidelity, bridging the gap between artistic vision and technical execution.
