For those of you with proper video cards that do not have difficulty with precipitation scripts, here is a merged map of the scenario with both precipitation and the latest bugfixes.

Unfortunately, some quirk of a few people's machines - which I suspect were running integrated graphics - couldn't cope with precipitation, even after bugfixes were made, and so Pfhorrest ordered it cut from final release. Although the effect on most levels is subtle due to an A1 limitation on having 1024 objects, I thought it well worth the effort of maintaining. So, before I cut the lua from the main scenario, I created a branch to preserve it, and left the supporting alterations to the Shapes file in the main branch.

Naturally, you'll need to download Eternal 1.2, found here,, to use this map.

Then, download this map file, drop it in your Eternal directory, and select it in Environment preferences.

To test whether your machine can handle this, skip to level 13: A Friend in Need, and see if your framerate drops when you walk outside. My 12 year old rig gets 20 FPS with everything on, but some players have reported as little as 0.5 FPS with precipitation.

Since this is an altered map and not a plugin, it will not be compatible with save games from the official release or the previous 1.2.0 version of this enhanced map.

Co-op players, please ensure that everyone has the same version of the map.
