Version 3.2

Last update: April 7, 2026

Substance 3D Sampler 3.2 introduces an end-to-end material digitization workflow that captures and processes the material physical size, new filters as Cloth Weave and Channel Switch and the ability to create custom metadata.

Release date: 25 January, 2022

Major Features

Physical Size

A new material scanning workflow that captures and processes the physical size of materials is introduced in this release.

Match the actual physical size of your samples/images in a digital context to create physically accurate materials in any software.

  • [Application] Crash at exit
  • [Application] Crash sometimes when clicking “Starter Assets” in the Assets panel
  • [Application] Crash when deleting a material
  • [Application] Environment variable “SUBSTANCE_DISABLE_SPECIFIC_FEATURES” is still active when set to “0” or “”.
  • [Application] Freeze while saving a project with multiple materials
  • [Application] Importing an image can lead to a crash
  • [Application] Missing some starter assets on first launch
  • [Export] Exporting an asset sometimes leads to a crash
  • [Layers] Cannot import images when the layer panel is closed or invisible
  • [Layers] Changing the language causes the current asset to recompute
  • [Layers] Changing the usage of an imported image does not upate which filter variation to use
  • [Layers] Image to Material (AI) is sometimes not computed when tweaking layers below it
  • [Layers] Image to Material (AI) sometimes recomputes when not needed
  • [Layers] No update is suggested when a custom filter is updated on the disk

  • [Layers] Some layers are still computed even when not visible
  • [Layers] The 2D view tools may be broken when toggling a layer visibility
  • [Layers] The UI freezes when using Image to Material (AI)
  • [Layers] Toggling the visibilty of the Transform filter layer breaks the 2D view tool and may lead to a crash
  • [Layers] Too many recomputations when removing a layer from the layer stack
  • [Layers] When a compound filter contains an unusual or custom input/output, Sampler doesn’t compute it
  • [Performance] Asset panel is slow to open
