What You'll Learn
Substance Painter does not allow for texture set merging
Substance Painter is a powerful software that has gained popularity among its users. However, it does not currently allow for texture set merging. This means that users cannot combine multiple texture sets into one Albedo, Roughness, Metal, and Normal map within the software itself. While Substance Painter offers excellent masking and layering capabilities, users seeking to merge texture sets will need to rely on external tools or workarounds.
The inability to merge texture sets in Substance Painter has been a longstanding issue for its users. Many have expressed their frustration and surprise that such a powerful software lacks this feature. As a result, users have had to resort to alternative methods to achieve their desired outcomes. One common suggestion is to use a Material ID map, which can be effective during the painting phase but may reduce flexibility during the baking phase.
To address the lack of texture set merging in Substance Painter, users have proposed various workarounds. One approach involves exporting the textures as document channels, exporting a plane from a 3D app, and then utilizing layers to apply the old textures in a new Painter project. Another method is to manually merge the texture sets in external software such as Photoshop or Substance Designer. While these alternatives exist, they may not always be ideal and can sometimes be time-consuming.
The developers of Substance Painter have acknowledged the requests for texture set merging and have discussed the possibility of adding this feature. However, they have also highlighted the complexities involved in implementing such a feature, especially regarding detecting UV islands, handling overlapping UVs, and maintaining clarity for beginners. As of now, there is no definitive timeline for when texture set merging will be available in Substance Painter, but the development team is working on updates to address this limitation.

Workarounds include using Photoshop or Substance Designer
While Substance Painter does not have a built-in feature for merging texture sets, there are workarounds that can be employed to achieve this. One such workaround is to use Photoshop or Substance Designer to combine the texture sets after exporting them individually from Substance Painter.
Step 1: Export Texture Sets from Substance Painter
- First, ensure that your project is ready for export by checking the List of Exports tab, which shows the maps currently set for export.
- Next, access the Export Textures dialog by going to File > Export Textures or using the keyboard shortcut Ctrl/Cmd + Shift + E.
- In the Export Textures dialog, you can customize the format and settings of the exported files. Make sure to enable the export of texture sets and adjust the settings according to your requirements.
- Finally, export your texture sets by following the standard export procedure in Substance Painter.
Step 2: Combine Texture Sets in Photoshop or Substance Designer
- Once you have exported all the individual texture sets, open Photoshop or Substance Designer.
- In Photoshop, import the exported texture sets and use the software's tools to combine and edit the textures as desired. Photoshop provides a wide range of tools for working with textures, including layering and masking options.
- Alternatively, in Substance Designer, you can create a new substance file and import your exported texture sets as input nodes. From there, you can use the node-based workflow to combine and modify the textures using a variety of tools and filters.
Step 3: Save and Export the Combined Textures
- After combining and editing your textures in Photoshop or Substance Designer, remember to save your work.
- Export the combined textures in your desired file format, ensuring that the bit depth and resolution meet your requirements and are compatible with your intended use.
By following these steps, you can work around the limitation of not being able to merge texture sets directly in Substance Painter. Utilizing Photoshop or Substance Designer gives you the flexibility to combine and manipulate textures according to your specific needs.

A free app can merge texture sets
As of 2015, Substance Painter does not allow users to merge texture sets within the app. Users have expressed frustration over the lack of this feature, as they have to resort to manually merging texture sets in Designer or Photoshop, which can be a time-consuming and tedious process.
However, there is a free app called Substance Texture Set Merger, which can be used to easily merge multiple Texture Sets in Substance Painter. This app allows users to work with multiple Texture Sets and provides added benefits, such as the ability to alter the visibility of different parts of the Substance Painter model. After completing the texturing process across all the Texture Sets, users can export the textures and use the app to combine them into one texture set.
Another free tool that can be used to merge texture sets is the Merge Texture Set Utility, created by Wes McDermott. This tool is a Substance Designer graph packed into a .sbsar substance archive and can be opened with the free Substance Player. It allows users to combine different sets of textures, making it useful for combining texture sets for the final output to be imported into a game engine.
Additionally, Blender, a free and open-source software for 3D modeling, animation, and rendering, can also be used to combine textures into one image. While Blender does not directly merge textures, it provides tools and workflows that enable users to achieve the desired result of a unified model with combined textures.

A workaround is to use a Material ID map
As of 2025, there is no way to combine texture sets for export from Substance Painter. While there are some workarounds, such as re-baking the mesh maps or using additional software to combine the maps, these can be impractical and may result in artifacts.
One workaround is to use a Material ID map. This can be a good solution during the painting phase, but it may reduce flexibility in the baking phase. To use this method, you can follow these steps:
- Assign different materials to different faces of the model in Blender. This makes it easier to assign materials to the model in Substance Painter without having to paint in masks.
- Export the mesh from Blender with different materials, bake maps, and then export again with one material to import into Substance Painter.
- In Substance Painter, use the ID map bake to create a mask that will help you merge the texture sets. You can do this by clicking the Bake Textures button and choosing to bake the ID map only.
- Use the Polygon Fill tool or color ID map to mask areas of the model. If you need to hide parts, you can add a fill layer with only the opacity channel set to 0.
While this workaround may not be perfect, it can be a viable option for merging texture sets in Substance Painter. It is important to note that this method may reduce flexibility in the baking phase, so it may not be suitable for all use cases.
