Congratulations for the work accomplished. Finding myself in the alpha moonbase gave me tears in my eyes. I read your comment on the possibility of modeling the cockpit of the eagle and I think that the problem comes from the fact that the interior dimensions (the film set) do not correspond at all with the exterior dimensions (model). http://catacombs.space1999.net/main/cguide/umeaglescale.html
Maybe the solution is to do the interior in a box outside the eagle?
Well done again! thank you and keep going.
