Project Creation

The new project creation window allows to create a project file to store the 3D model and its texturing information.

A new Texture Set is created per material definition found on the imported 3D model. This means multiple objects can be imported through a single file (even with overlapping UVs) if they have different materials.

Creating a New Project

To create a new project click on File > New to create a new Substance 3D Painter project.

Below is an explanation of all the parameter available in the New Project window.

Base Settings

Parameter	Description
Template	Allows to specify a template that will define the default settings of the project. A template contains the follow parameters: Texture Set settings Display settings Baking settings Shader resources (including attached textures) Environment Map file Note: Templates are *.spt files that are created from an existing project via the File menu and saved inside the Assets folder to be easily shared with team members.
File	Click on the "Select" button to specify a 3D model file to load. List of supported file formats: .abc (Alembic) .dae (Collada) .fbx (Autodesk FBX) .gltf (GL Transmission Format) .obj (Wavefront OBJ) .ply (Stanford Triangle Format)

Parameter

Description

Template

Allows to specify a template that will define the default settings of the project. A template contains the follow parameters:

Texture Set settings
Display settings
Baking settings
Shader resources (including attached textures)
Environment Map file

Note:

Templates are *.spt files that are created from an existing project via the File menu and saved inside the Assets folder to be easily shared with team members.

File

Click on the "Select" button to specify a 3D model file to load. List of supported file formats:

.abc (Alembic)
.dae (Collada)
.fbx (Autodesk FBX)
.gltf (GL Transmission Format)
.obj (Wavefront OBJ)
.ply (Stanford Triangle Format)

File type-specific settings

When a USD is selected, other file type-specific settings become available.

Parameter	Description
Scope and variants	Allows to select a specific part of a USD file. By default, it is set to 'Root', which means the entire USD file will be used to create the Painter project. Change... opens a new window that displays the content of the USD. If variants are detected, it is possible to select a specific variant for project creation. Scope and variants can be changed after project creation in Project configuration settings. Note that - Only the modeling variant selection will have any impact on the project. Variants nested within variants are not currently detected.
Subdivision level	Applies to geometry that has subdivision. It allows to specify how much you would like to subdivide your mesh for texturing in Painter. If subdivision is explicitly set to 'none' within the USD file, this setting is grayed out. Subdivision is applied after UV unwrapping, so it would not alter the shape of the mesh's UVs. Subdivision levels can be changed after project creation in Project configuration settings.
Frame	Applies to USDs in which animation is detected. It allows you to select the frame which will be used to create a Painter project. If there is no animation in the selected USD file, this setting is grayed out. Frame can be changed after project creation in Project configuration settings.

Project Settings

Parameter	Description
Document Resolution	Defines the default texture resolution of the project for each Texture Sets. The resolution can go up to 4K (4096x4096 pixels) when working inside the application and 8K (8192x8192 pixels) when exporting. The resolution can be changed at anytime later on via the Texture Set settings. Note: 8K export requires at least 2.5GB of VRam on the GPU to be available.
Normal Map Format	Defines the Normal map format for the project, can be either DirectX (X+, Y-, Z+) OpenGL (X+, Y+, Z+) Note: As a reminder: Unreal Engine use DirectX by default. Unity use OpenGL by default.
Compute Tangent Space per Fragment	If enabled, the Bitangents are computed in the fragment (pixel) shader instead of the vertex shader. This parameter impacts the way the Normal map is decoded by the Shader in the viewport. Changing this settings will require to rebake the Normal map. Note: As a reminder: Unreal Engine needs this setting to be Enabled. Unity needs this setting to be Disabled (or enabled if you are using the HDRP workflow). For more information see the Tangent Space page in the Bakers documentation.

UV Tile Settings (UDIMs)

Note:

These settings cannot be modified once the project has been created.

Parameter	Description
Use UV Tile workflow	If checked, the imported mesh will be processed differently to allow painting outside the regular UV range (0-1). Project using UDIM should enable this setting. The processing of the mesh may differ depending on the setting For more information, see the UV Tile documentation. Possible values:
Preserve UV Tile layout per materials and enable painting across tiles UV Tiles (UDIMs) are imported and grouped per material assignation on the mesh. This means a single Texture Set can contain multiple UV Tiles which are visible side by side in the 2D View. UV Tiles which are within the same Texture Set can be painted across seamlessly.
Convert UV Tiles into individual Textures Sets (legacy) UV Tiles (UDIMs) are separated into individual Texture Sets and renamed, ignoring any material assignation. Each UV Tiles is moved to the UV [0-1] range to be paintable.

Import Settings

*Parameter*	*Description*
Import Cameras	If cameras are present in the mesh file, they will be imported in the project and accessible as preset for visualization. Note: Substance 3D Painter doesn't support some cameras in certain conditions : Physical cameras from 3DS Max. Orthographic cameras stored in Alembic files (*.abc).
Auto-unwrap	If enabled, missing UVs on the imported mesh will be generated. The processing may change depending on the settings selected via the Options button. For more information, see the Automatic UV Unwrapping documentation.

Import baked maps

Use the Add button to loads texture files as Mesh maps and automatically assign them in the Texture Set settings. A specific naming convention must be followed to have the mesh maps automatically assigned to their Texture Sets. Mesh maps can also be baked directly inside the application, see the Baking documentation .

Naming convention: TextureSetName_MeshMapName

Example: DefaultMaterial_ambient_occlusion.png

List of supported Mesh maps and their naming:

Mesh map	Filename convention
Ambient occlusion	ambient_occlusion
Curvature	curvature
Normal	normal_base
World Space Normal	world_space_normals
ID	id
Position	position
Thickness	thickness

Color management

This section controls the color management settings that will be used by the project. By default it is set to Legacy (sRGB / Linear workflow).

Take a look a the color management documentation to learn more details on how to use this workflow and what the settings are doing.
