v0.6.0-beta

Added

• Distant Horizons' far terrain now casts into the pack's shadow map. A pack that ships a
  dh_shadow program has it drawn, from the light, over the same distant land its dh_terrain
  draws for the camera, so a far hill lays a shadow on the ground instead of only shading itself
  out of its own depth. Packs that write dhShadow.enabled=false are taken at their word, which is
  most of them; the one pack tried here that ships the program keeps it behind a setting of its own
  and it has to be switched on. It also follows the two words that govern the near world in the map,
  so a pack that keeps the world out of its own shadow map keeps the distant land out with it. What the map holds is the distant land the camera can see, which is
  narrower than under Iris: that mod gets a second list of it, built for the light, and there is no
  second list to be had here.

Changed

• Two things taken on every frame are no longer taken for a pack that cannot read them. The
  copy the shadow map is read from as shadowtex1 is sixty-four mebibytes a frame at a shadow map
  of 4096, and the depth kept from before the hand is a full screen image and a draw on every frame
  the hand is drawn. Each is now skipped where no file of the pack writes the name that reads it,
  which the log says out loud when it happens. Of the eight packs tried here, one skips the shadow
  copy and five skip the depth.
