How do I fix the Redshift warning: "[OBJECT] is instanced and uses adaptive tessellation, which isn't supported"?

Problem Redshift is showing a tessellation warning on an object that is being used as an instance.

This happens because screen-space adaptive tessellation calculates how much to subdivide a surface based on its distance from the camera. Since instanced objects share the same underlying geometry but can exist at different positions in the scene, Redshift has no way to calculate a unique screen-space tessellation value per instance. This is a fundamental limitation of how instancing works, not a bug.

Solution Switch from screen-space adaptive tessellation to fixed tessellation in the Redshift Object tag attached to your source object.

Here is how to fix it

  1. Select the Redshift Object tag on the object being used as the source for your instances. 
    If you have multiple source objects being instanced, select all of their Redshift Object tags.
  2. Go to the Geometry tab.
  3. Uncheck Screen Space Adaptive.

  4. Set Minimum Edge Length to 0 (zero).
