A couple of weeks ago I posted a new version of Reality, 4.3.1, that fixes some issues with the saving and loading of automatic presets. No other changes were made and I strongly advice any Reality 4 user to update to this version. Both DAZ and Renderosity have received the updated version and you can re-download the product from there, if you purchased it with those distributors. Otherwise, simply re-download it from this site.
Again, this update has critical bug fixes for the saving and loading of Automatic Presets and every Reality 4 user should update. The update is free.
