This release fixes the following issues in the Voxel Editor:

  • Level of detail system for orthographic views changed to use visible distance instead of distance to objects
  • Shadow maps now correctly frustum culled when using an orthographic camera

We've also changed the World Properties window to improve performance by only calculating dimensions on window appearance, loading a world, or when manually refreshed. (Menu View > World Properties)

In Avoyd 0.8.14 (below) - The level of detail is fixed: it now depends on the orthographic width so details are preserved depending on the setting 'LOD Change Distance' (in menu Graphics Quality).
