Flow maps can be challenging to create in Substance Painter, and while there are no definitive methods, users have shared their workflows to help beginners get started. One popular method involves using the Normal channel and brush parameters to paint flow maps. This includes creating a 16x16-pixel normal map texture with a specific colour, adding a Normal channel, enabling the follow path feature, and painting on the mesh to draw directions. Another approach is to import a mesh and normal map texture, create new layers, switch to normal mode, and paint strokes following the hair flow direction. These techniques can enhance the appearance of hair and water shaders in 3D projects, but they may also require additional refinement in Photoshop.

What You'll Learn
Importing a mesh and normal map texture
To import a mesh and normal map texture in Substance 3D Painter, follow these steps:
First, create a normal map texture of 16 x 16 pixels, with the colour 128, 255, 128. This colour is equivalent to a vector looking up in DirectX. In your Substance 3D Painter project, add a Normal channel via the Texture Set Settings if one doesn't already exist. You can do this by going to the Texture Set Settings and creating a new Texture Set with the Normal Mixing setting set to 'Replace'. This will allow you to override/paint the normal map.
Next, load the normal map texture into the Normal channel slot and enable the 'Follow Path' feature in the brush parameters. Make sure to disable the other channels. Now, you can start painting on the mesh with the 'Follow Path' setting enabled, and your brush strokes will draw directions into the normal map.
If you want to export your textures from Substance Painter, go to File > Export Textures (Ctrl + Shift + E). You will get three different textures: Colour, Normal Map, and a packed texture that contains Ambient Occlusion, Roughness, and Metallic. You can define the exported texture resolution size and choose to export a fourth Emissive texture if needed.
Additionally, when working with normal maps, you can load a Normal resource into the Normal slot of the Material section of your painting tool. Painting with a normal map is similar to Height Map Painting, but with the added precision of a baked normal. Normal maps have their own blending modes in the layer stack, and you can change the default colour space when loading a normal map into the slot of a material.

Creating a new layer
First, import a mesh and normal map texture, and apply the normal map to the mesh. This will serve as the foundation for your flow map. Then, create a new layer and assign a simple normal map texture to paint on. This new layer will allow you to work on specific sections of your project without affecting the rest of the image.
Once you have created the new layer, switch it to normal mode. This step is crucial as it allows you to paint strokes in the direction of hair flow using a hard brush. Imagine you are painting individual strands of hair and following the direction in which they would naturally fall or be styled. This technique is often used for groups of strands to speed up the process.
After painting the desired number of strands on the new layer, you can create additional layers and repeat the process, building up the complexity and detail of your flow map. Remember to paint in the direction of hair flow to achieve a natural and realistic result. Finally, you can export each layer separately and layer them in Photoshop for further refinement and blending.

Switching the layer to normal mode
When working with flow maps in Substance Painter, you may encounter situations where you need to adjust the blending mode of your layers to achieve the desired effect. Here's a detailed guide on switching the layer to normal mode:
Understanding Layer Stack and Blending Modes:
Start by understanding the Layer Stack concept in Substance Painter. The Layer Stack allows you to manipulate the layers of a Texture Set, which includes hiding and unhiding layers, changing their opacity, and adjusting their blending modes. The layers are stacked in a specific hierarchy, with the bottom layer being drawn first and the top layer being the last item rendered.
Normal Map Blending:
When working with normal maps, it's important to understand the blending modes available. Normal map blending modes are specifically designed for the Normal channel in a Texture Set. By default, the blending mode of the normal channel on any new layer is set to "Normal Map Details". However, you can change this setting to "'Replace' or "Normal".
To switch a layer to normal mode, follow these steps:
- Select the desired layer: Choose the layer you want to switch to normal mode. For example, if you have a sticker image on top of a cloth layer and want the sticker to appear without the cloth's normals affecting it, select the sticker layer.
- Change the Blending Mode: In the Layer Stack window, locate the top-left dropdown menu. This dropdown controls the view mode of the layer stack. From this menu, select "Normal" as the blending mode for the selected layer. Alternatively, you can use the keyboard shortcuts available to quickly switch between blending modes.
- Adjust Opacity (Optional): If you want a subtle underlying effect from the layers below, you can adjust the opacity of the layer set to normal mode. Reducing the opacity will allow some of the details from the underlying layers to show through.
- Create Multiple Layers (If Needed): In some cases, you may need to work with multiple layers to achieve the desired effect. For example, if you're working with 1000 skull images and want each skull to be distinct, consider creating a new layer for each skull and switching the normal channel blending to "Normal" for each layer.
- Use Fill Layers: When working with normal maps, it's common to use fill layers. Create a new fill layer and put the baked normal inside the "normal" slot via the properties panel. Remember to adjust the default tiling of the fill layer if it's not set to 1.
By following these steps, you can effectively switch the layer to normal mode in Substance Painter. This will help you control how the layers interact and blend, allowing you to create the desired visual effects for your project.

Painting multiple layers
To begin, you'll need to import a mesh and normal map texture, and apply the normal map to the mesh. This forms the foundation for your flow map. Next, create a new layer and assign a simple normal map texture to it, which will be the base for your painting. It's important to switch this layer to normal mode to ensure your brush strokes align with the direction of hair flow. Use a hard brush for more defined and precise strokes.
The key step now is to paint multiple layers, enhancing the complexity and depth of your flow map. With each new layer, you can add more detail and refine the overall appearance. Remember to erase any unwanted tails to improve the falloff, creating a smoother and more natural transition between the layers.
Finally, export your work to Photoshop or similar software for further refinement and polishing. This step allows you to fine-tune the flow map, adjust colours, and enhance the overall appearance to match your vision.
While the process of painting multiple layers can be tedious and time-consuming, it offers a significant advantage. By using multiple layers, you can create intricate and realistic flow maps, particularly noticeable when working with hair or similar textures. The time invested in painting multiple layers pays off in the level of detail and visual appeal it brings to your project.

Using Photoshop for refinement
Substance 3D Painter has revolutionized the field of 3D graphics, providing artists with powerful tools to create detailed and realistic textures. Its integration with Adobe Photoshop enables artists to leverage Photoshop's extensive toolkit for additional texture editing and refinement.
While Substance Painter is the preferred tool for texturing, Photoshop can still be useful for certain tasks. For instance, if your bake from Substance Painter isn't perfect, you can take it into Photoshop for touch-ups. Photoshop can also be used to create alphas for brushes, allowing you to repeat decals for specific models. Additionally, Photoshop is a good tool for learning the fundamentals of texturing and can be used to paint flow maps for hair, with each layer exported separately and then layered in Photoshop.
To refine your creations in Photoshop, you can use dilation to make your strokes bleed out and then blur the entire image, creating a smoother effect. You can also use Photoshop's extensive toolkit for more advanced texture editing. For example, you can use the Lasso selection tool to paint a specific pattern that benefits from Photoshop's tools.
Substance Painter's seamless integration with Adobe Creative Cloud and its support for industry-standard workflows make it a powerful tool for 3D professionals. However, Photoshop can still be a valuable complementary tool for specific tasks and refinements, especially with its upcoming AI capabilities that will further enhance its functionality.
