Adaptive Subdivision



Modifier ‣ Subdivision Surface


Implementation not finished yet, marked as an Experimental Feature Set.

When using the Experimental Feature Set the Subdivision Surface Modifier gets changed to control the subdivision of a mesh at the time of rendering. For this, all the other settings are the same except the View and Render settings. These before mentioned settings get removed/renamed and the following settings are added:

Adaptive Subdivision

Use OpenSubdiv to give different subdivision levels to near and far objects automatically. This allows nearer objects to get more subdivisions and far objects to get less.

Dicing Scale

Multiplier of the scene dicing rate to determine the final size of Micropolygons in pixels.


Subdivision off/on, Dicing Scale: 1.0 - 0.3 - 0.05 (monkeys look identical in viewport, no modifiers).

Known Limitations

  • Multi-user object data are currently made single users, leading to increased memory usage. For those it is better to use non-adaptive subdivision still.

  • Multi-view renders can have some inconsistencies between views.


Instances are not tessellated individually. Instead, the original object is tessellated and then duplicated on all instances. To take advantage of both adaptive subdivision and instancing you should place the original object at the position of the instance that is closest from the camera.
