I undestend perfectly your goul is to create something very hardware demanding from beginning but i will say keep in mind Unity + DX it have a limit (that i was post link from microsoft & unity) & when i say it can create problem i mean special to Scatter & Eve was have a lot issue to make them work & still they have issue with DX11 & opengl (i not know all details about but, i know is very sensitive problem), same keep all project on 8k alternative it will allow more ppls to use aka more happy community I was play all this time with file from your pack & already resale 10800 & 16200 dds file to 8k (thx to an old dds aplication converter, adbobe photoshop was can't handle 16200 one to import) + was try to make work with KSP 1.2.2 with was create more mess but that because i like to test thing.
Np is fine you not need to be sorry is a project is Jeb fault like always for everything what it happen in KSP
