From looking at the last pic (hyperion next to the firebird) I would think the size is fine.
Currently though the hyperion is a tad longer it is about twice the width with the wings, but then they could be justified in the additional role as a combat craft so would need the extra control surface, the main body is similar in width to the Firebird's, it's just going to take up more landing space in the mission maps so something to think about.
also progress
ironed out most of the geometry in the first half of the craft, the nose has changed shape slightly as a result but i dont think it's lost the general spirit. this will probably be the last human eye view of the craft as I am now focusing on the top and aft half geometry which cant be seen too well from the ground
Less dramatic but I think shows the current scale nicely and just how horrible the back half of this thing is and as this will be the most common view of the craft it needs fixing.
For reference the red light is where the troop bay doors are
Different 3D programs often import to different scales and then don't necessarily export the same way. The scale will still need to be checked in-game, especially to test how the interior (soldier cabin) lines up to the map grid. We will need to make sure it fits 2x2 grids and not too much extra space on either side so the player is not confused.
indeed, I have tried to keep the Hyperion relative to the Firebird model so hopefully when the model is scaled to fit the troop bay to a 2x2 size in game the Hyperion will take up the same amount of space as indicated above
if you want a height comparison
