Eudoxus Update #1.5

It has only been a couple days since the last update, however a few small changes have been made which I’m keen to show.

The first is the improvement of the specular maps. The ground is much less shiny and a lot more natural looking. For the ground cover, I’ve also decreased the density of the rocks, as I feel that it may have been a bit too dense prior to this change. Below is a picture of these changes:

The ground on the moon.

Secondly is the heightmap. I decided that while the first heightmap had a lot of definition, it was difficult to remove the banding of the image, which was causing visible ridges in the terrain. Therefore, I used a new heightmap from the same website as before ( This heightmap can be seen below:

The updated heightmap for the mod.

As can be seen, this heightmap still has the definition of a crater, yet it’s a lot more subtle, and the contrast is much higher without any visual artifacts. Here’s how it looks with the sun on the horizon:

The horizon on the moon.

The subtle and sparse ridge around the heightmap ensures that the horizon looks slightly cratered without being overwhelming. As can be seen, the specular maps also look much better with the sun glaring on the moon. Some lighting tweaks were also made, to give the lighting and environment more natural colours.

I am now happy with the way the worldspace looks and reacts to light. The next step is the implementation of the space suit, as well as the life support system. After much experimentation with Project LUNAR, the cleanest way to implement this has been decided already.

Eudoxus Update #1

Here is the first development update, as well as the first post, for Eudoxus, the successor to Project: LUNAR! I am rebuilding the entire mod from scratch, keeping realism, atmosphere and of course entertainment in mind!

In this first update, the easiest bit was creating the world. To save time, I’ve decided to use a public domain pre-existing heightmap of a crater (courtesy of This is the heightmap:

The heightmap for the mod’s landscape.

This had to be manipulated a little bit to ensure that it imported correctly, but it is now functioning in-game. I used a lunar rock landscape texture made by┬áCameron ‘cron’ Fraser under the Creative Commons license. Despite some tweaks which need to be made to the specular map, it is a perfect fit for Fallout 4!

I then had to create a custom climate, and in this climate, I had to disable the moon (for obvious reasons). I then had to create a custom weather type with no ambient colours and lighting, an intense sunlight and sun glare, and a fully black sky. This weather uses a custom image space, which adds a bit of blue (to ‘cool down’ the image, as well as tweaks to depth of field, fog and bloom. After this, the base landscape was finished!

Here is what the landscape currently looks like:

As can be seen, some work still needs to be done (namely a modification of the specular map and a retexture of the lunar surface rocks), but it definitely captures the vibe of the moon pretty well.

And this is it for the first project development update. As I go through milestones during the development of this project, I will be recording the updates on here as they occur. The development of this mod should be relatively fast, as I intend it to be a much cleaner experience than Project: LUNAR, while still being rich with things to do!
