I would certainly assume that as the mod is not being charged for... same way in which my work is free for all, but im also all about knowledge freedom - so i'll share one or two nuggets of how i at least managed to get a starsphere working.
I tended to re-work originals to start with, but as you have pointed out it tends to look naff adjusting the existing ones so i took a step back and looked at the concept of a starsphere...
Essentially speaking the txture wrap issue need never be a problem because all thats needed is a surrounding display - who says it needs to actually be a sphere so i downloaded lots of hi res nebula pics from nasa and started to play with alternate methods...
put simply as apposed to grafting images to the inside faces of a sphere - i simply had lots of slight overlapping ,call it, screens going around and all textured up with a nasa nebula and this started to achieve results that had true potential.
The Denabe SS itself was a 2nd work around - i was going for a big band of nebula going around the system with an anomoly at one end and thats what i did - sad to say the video on media fire appears to have expired so i'll try and dig it up.
I'm not here to burst anyones bubbles - im simply proud of my work but as im being branded a liar (by you whom i have offered my work and help to) then very well, i shall try and put together a package of mini demos of the stuff i have done.
