Unity 2.4.0

Last update: Thu Feb 26 2026 00:00:00 GMT+0000 (Coordinated Universal Time)

WARNING

Unity changed the default build architecture to x86 instead of x86_64.
Scripts will not run if they reference Substances. You will need to change back to x86_64 and the build will work.

New Features:

HDRP project support added (preview)
Added Preferences in the Substance menu
Added ability to set default Substance resolution import setting
Added ability to set default Normal compression
Added ability to generate all outputs on an import of a Substance
Support for custom outputs + outputs with the same usage
Added Platform Resolution settings
Added IL2CPP support Bug Fixes

Bug Fixes:

Fixed a bug where opening Substance Source on Mac OS would give a Linux error
Reduced time that it takes when switching platforms. Texture conversion for mobile platforms is now done on build rather than when switching target platform.
Assertion failed error when importing sbsar
Upgrading projects using .NET 3.5 causes substance materials to break
Substance source not supported in linux dialog appearing on OS X
Graph name change destroys prefabs & scene file in ForceText serialization mode
Substance materials with multiple outputs using the same usage will break Plugin doesn’t support custom outputs in sbsar

Known Issues:

When upgrading a project from 2017-2018/2019, after the user imports the Substance plugin, Unity must be restarted for the project to be updated.
Workaround: Create a package of the assets/project and import that package into a newer project with the 2.4.0 plugin. The Substance files should be converted correctly.
Unity has changed the default build architechture to x86. Currently, the Substance plugin only supports x86_64.

No Longer Fully Supported:

Substance Live Link has been removed from the Asset Store package. (The package can still be downloaded from Substance Share)
