Crash while baking




Substance Painter may crash during the baking process on some configurations. This page regroups a list of know issues and how to mitigate them.

Crash with Baking preview

By default Substance Painter display in the viewport the in-progress state of the baking of a texture. On some computer this feature may lead to instabilities.

To disable it:

  1. Use Edit > Settings to open the main settings
  2. Under General scrolls down to the section named Baking Options.
  3. Uncheck/Disable the option Enable live preview baking process.

Crash with GPU Raytracing

On some GPU with unstable drivers, the baking process may lead to crashes because of the GPU raytracing feature.

To disable it:

  1. Use Edit > Settings to open the main settings
  2. Under General scrolls down to the section named Baking Options.
  3. Uncheck/Disable the option Enable GPU raytracing.

Crash with Ryzen CPUs

The application may crash during the baking process on some computer configuration running with a Ryzen CPU. An update of the BIOS usually fix the problem.

This is related to multi-threaded computations. Many Motherboard constructors have issued new BIOS updates to fix this issue, so we recommend applying the update. Refer to the Motherboard manual and constructor website for more information.

Incompatible Assbin files

By default when baking, high-poly meshes are pre-processed into *.assbin files to speed-up rebaking later. In some rare cases, these files may crash the application if they have been generated with a different version. Simply deleting them should solve the problem, as they will be regenerated.
