Control (UI) Default Value Function

pixel_error 0 Sets the acceptable tessellation error, in pixels, as seen from the

camera. If there’s no displacement, pixel_error represents the

distance from the subdivided mesh to the true or limit surface.

The smaller the error, the closer to the limit surface a mesh is

(with less inter-frame popping when the subdivision level

jumps).

If displacement is enabled, pixel_error represents the size - in

pixels - of the subdivided quads. A value of 0 disables adaptive

subdivision.

subdiv_adaptive_

metric

auto When set to auto subdiv chooses between Edge Length and

Flatness modes depending on the displacement of the mesh. If

there is displacement, the Edge Length algorithm is used. If not -

or if displacement is ignored in the global options - Flatness is

used. You can also manually select EdgeLength or Flatness.

The subdiv_adaptive_metric attribute controls whether adaptive

tessellation is guided by patch edge lengths, or the difference

between the limit-surface, and control-surface (measured in

pixels at the patch vertices). The pixel_error is either the edge-

length size, or the error-tolerance.
