@Maelstrom Vortex You can simply disable the "smart" sun tracking in kopernicus by renaming GameData/Kopernicus/Config/SolarPanels.cfg to something else without the .cfg extension. It should revert it to stock solar panels without the buggy "smart" tracking.
This is quite common issue for multi-platform software, not all filesystems are case-insensitive like FAT/NTFS. Thanks again for fixing this, I'm looking forward for the new release and all the visual goodies you are currently working on.
There is an issue with this planet pack and case-sensitive filesystems, and because of it it's broken on Mac and Linux. Most references to texture files have mismatching case.
Like... From Carphos.cfg:
Material
{
texture = IA_Revived/TRAPPIST-1System/Carphos/Textures/Carphos_color
normals = IA_Revived/TRAPPIST-1System/Carphos/Textures/Carphos_normal
But the actual files are named Carphos_Color.png and Carphos_Normal.png (notice the capital letters).
@ProtoJeb21 Would be great if you can review all .cfg files to make it compatible with other operating systems before 1.3 release. Thanks!
