Many DirectX shaders are crashing 3ds Max 2021, including the Wall Worm Blend Materials. Symptoms of this bug:

  • Opening a Wall Worm WorldVertexTransition or Lightmapped_4WayBlend DirectX material in Slate causes Max to crash to CER.
  • Selecting in the viewport an object with a Wall Worm WorldVertexTransition or Lightmapped_4WayBlend DirectX material in Slate causes Max to crash to CER.

To fix this bug, you must install 3ds Max 2021.3 (the third update to 2021).
