Learn how to set up your Substance 3D Painter project to work in the best conditions.
Prepare your 3D mesh
With Adobe Substance 3D Painter, you can texture and paint 3D meshes. Prepare your meshes before importing them to Painter for the best results.
Substance 3D Painter requires a 3D mesh to start a new project. These 3D Meshes are made of Polygons, which are made by combining vertices and edges which define faces. These faces can then have Material definition assigned, which become Texture Sets in the application.
Faces also have UV coordinates, which are a 2D representation of the mesh as it would be when unfolded. These coordinates are used to map a bitmap/texture onto the mesh surface. In Substance 3D Painter, this is where the information is saved when painting on the mesh surface.
Geometry
To prepare a mesh for Painter, ensure that the mesh geometry is clean to avoid issues in the texturing process. Problems to look out for include:
- Small triangles
- Non-manifold geometry
- Incorrect or invalid normals
- Doubled vertices, edges, or faces
UVs
Painter and other 3D applications use UVs to understand how to apply textures to a 3D mesh. UVs are like wrapping paper with instructions on how to wrap the 3D mesh. The process of preparing UVs is often known as UV unwrapping as a result. Painter includes automatic UV unwrapping tools that you can use to create UVs for your mesh, however you will almost always get the best results by manually preparing your UVs.
When you unwrap your UVs, look out for:
- Overlapping UV islands
- UV islands outside the 0-1 space
- Stretched faces
- Inconsistent texel density
Create a Project
Discover the new project creation window and its settings.
To create your project:
Click Select to load a mesh file.
Adjust project settings if needed.
Click OK.
|
|
Description |
|
Template |
Choose a template that updates the default settings of the project. |
|
File |
Click Select to choose the 3D mesh for this project. You can update the 3D mesh by using Edit > Project configuration. |
|
Document Resolution |
Select the resolution of your project. This will set the resolution for all texture sets in your mesh and can be updated later in the Texture set settings panel. |
|
Normal Map Format |
Painter supports both DirectX and OpenGL normal maps. Which normal map you should use depends on which application you intend to use the normal map in. |
|
Compute Tangent Space Per Fragment |
This setting changes how normal maps are baked. Whether to enable or disable this setting depends on which application you intend to use the normal map in. |
|
Use UV Tile workflow |
The UV Tile workflow, also known as UDIM, allows you to texture across a larger UV range. Enable this setting if your mesh is set up to be textured in this way. Hover over the information icons to the right of these settings to learn more about UDIMs. This option cannot be changed later. |
|
Import Cameras |
When enabled, cameras in the mesh file are imported into the project and can be used for visualization. |
|
Auto-unwrap |
Enable auto-unwrap to have Painter automatically unwrap your mesh to create UVs. Click Options to adjust whether UVs are generated for the entire model or only where UVs are missing. |
|
Import mesh normal maps and baked maps for all materials |
Click Add to include texture files baked in other applications in this project and automatically assign them in the Texture set settings. |
