Hey sorry for your troubles there, that is one thing I managed to forget to fix before releasing the buoyancy version (the shadow warnings noted above). I have turned them off now for the next release.
As far as the moon goes, all you should need to do is open the blueprint, go to the Components tab, select the moon, then in the details panel you should see a Static Mesh box with the moon selected. Change that to whatever you’d like, the material is being set from the “Set Sky Parameters” function which gets called from the Construction Script. So if you change the mesh, you will most likely want to change the Material as well.
The majority of those properties can be adjusted in the viewport, if you select the Skydome from the scene outliner, all of the properties can be found in the details panel.
For dynamically changing the values you will need a reference to the Skydome blueprint in the level blueprint and then set various properties. But the answer is yes, I will do a tutorial for that asap!
project is meant to be a demonstration of the and Skydome, not an executable program. While everything would work in a binary version, you wouldn’t be able to do anything other than look at it. For the time being I have no plans to make into an executable, it is meant to help other developers get a jump start at creating these systems in their own game. The project may never get to a point where it would be a standalone, so I cant make any promises. As it stands UE4 is required to use project.
