Comparing the Homeworld Motherships

After playing Homeworld 3 recently, I wanted to see how the Khar-Sajuuk and Khar-Kushan compared to the original Motherships (and, for that matter, how the original Mothership and Pride of Hiigara compared to each other) from the prior games, as well as Sajuuk an ancient ship discovered at the end of Homeworld 2 whose technology was incorporated into the next generation of Motherships, and the Kuun-Lan, the flagship in Homeworld: Cataclysm/Emergence, which is seen both its original configuration and its final appearance after several modifications over the course of the game. I extracted the models and texture maps from HWR and HW3 and set up this comparison scene. The scales are all directly as they came out of the game, cross-checked by the old trick of flying a fighter to one end and seeing how far the other one was with the move tool, so these are all to in-game scale.1The Kuun-Lan is at ~31% of the in-game figure, in accordance with the convention that the original Homeworld and Cataclysm/Emergence use feet as the in-game units, while the later games use meters. If anyone wants to use these images in another scale chart, the vertical edge of the image is 3,460 meters tall.

(Technically, the HW3 Motherships are upside-down compared to how they orient vertically in-game, but the top is their “hero” angle, and starboard is the usual perspective on the first two Motherships, so I had to compromise.)

However, I’m not entirely trusting of the in-game scale. After all, the original Homeworld’s manual says the first Morthership is “really” ten or twenty times larger than it is in-game. I made a second image, this time scaling the HW3 Motherships up so the size of their Hyperspace Core modules matched the similar feature on Sajuuk (the main cannon on the Khar-Sajuuk is clearly derived from Sajuuk, but the shape is different enough that there was nothing to scale-match), assuming since the ships from HW1 and 2 can all interact with each other in campaign and skirmish and are all Mothership-class, they’re all correctly sized relative to each other. There’s a little leeway involved, the two Hyperspace Core housings aren’t exactly the same shape, but this method makes the HW3 Motherships about 1.6 times longer than they are based on the in-game scale. The vertical edge of this image is 4650 meters tall, assuming the in-game scale for the HW1 and 2 ships is correct and they aren’t actually supposed to be twenty times larger.

I like this alternate scaling better, myself. Given how massive Sajuuk was compared to the Pride of Hiigara, I think it makes sense that a Mothership that was more-or-less built around it should be a similar leap in scale, revolutionary rather than the evolutionary change from HW1 to HW2. You can’t see it from this angle, but it also makes the Frigate launch bay and the fighter bays at the wingtips close to the same size as the prior Motherships’, rather than noticeably smaller, which is enough to make me wonder if the ship was scaled down after it had been designed for some reason. I did compare some of the other Homeworld 3 ships with their Homeworld 2 equivalents, and it appears if there was a post-design scale-change, the Motherships were the only vessels affected. Additionally, checking against the Hyperspace Core model (reused in Homeworld 3 from Homeworld 2 Remastered directly), there’s excessive amounts of room under the shaded circles on the Sajuuk’s module, the ends only barely exceed the circles of the Khar-Sajuuk’s module at the in-game size, and they’ll even fit centered under the domes of the Khar-Kushan’s module, properly rotated so they don’t collide (and the Khar-Kushan’s cores may not be the same shape or size as the three used in the Sajuuk and Khar-Sajuuk). So the smaller in-game scale for the ships is possible, even if I don’t personally like the idea of the ships echoing features of Sajuuk so closely but at a different size.

Thanks to ArkFlash for the Cataclysm/Emergence models. Homeworld 1 and 2 Remastered models were extracted with CFHodEd and Gearbox’s Modding Tools. Homeworld 3 models were extracted with UE Viewer and converted using Blender using this plug-in. All models were resurfaced and rendered in Lightwave.

Back to Basics with the Enterprise-G

A few days ago, Marc Bell released his CG model of the Titan-A/Enterprise-G from the final season of Star Trek: Picard. I’ve been acutely aware for the past… fifteen years… that I don’t just hop onto the computer to mess around and make some fun spaceship pictures like I used to. Despite my attempt to get back into the groove a few years ago, it didn’t quite take, possibly because I was scratching the 3D itch at my job at the time, and then Lightwave 2018 came out and my library of models assembled over the years and tweaked to my liking became more-or-less useless.

I recently started rebuilding a new, PBR-based set of models in Lightwave 2020, mostly thanks to the models of Chris Kuhn, Marc Bell, and Alexander Klemm, but I hadn’t really done anything with them yet. This new model was a good chance to, and since it hadn’t been officially converted into Lightwave, I got to dip back into my roots a little when I had to convert anything I wanted to use. Downloading a cool new model that was just mesh and textures, and really digging into it to get it to look right. I spent the weekend building out the lighting rig and doing various minor modifications and tweaks, like breaking out the formation lights and impulse glows so they could be animated, and found picked an angle to run a test render (a good thing, too, I found a tiny sliver of window-box sticking out of the hull). I thought it looked pretty good, so I did a final version adding a basic Sun/Earth/Moon three-point light setup, and that was that.

I tried to think of something more dramatic, and thought up a concept for another image, with the Enterprise-G over the Founder’s Homeworld seen in Deep Space Nine, returning the renegade Changelings who’d infiltrated Starfleet to their own people. Luckily, my prep came in handy, and I already had a Jem’Hadar fighter and a Defiant ready to go for a suitable escort. I spent a bit of time making new decals for the Defiant-A (I know in-canon the second Defiant had the same markings as the first one, but Ron Moore wanted it to be the Defiant-A, I wanted it to be the Defiant-A, so I made it that way). I was pretty far along before I remembered the Defiant was a museum exhibit now, so I just went with it, not having any better idea what ship Deep Space Nine might have assigned to it in the PIC era (or if there’s even still a DS9 at all). Maybe they flew it out as a goodwill historical thing.

Star backgrounds in both images are NASA’s Deep Star Map (though I should’ve been used the fictionalized version without recognizable constellations for the second render). The Founder homeworld is NASA photo ISS048-E-010018, recolored in Photoshop to match the planet as seen on the show. Both images had compositing and post work done in After Effects.

After over a year, I’ve reached the end of my 2020 pandemic modeling project with the completion of the version of the stargate used in Stargate Atlantis. Alongside the movie and SG-1 versions, that makes a complete set for this basic design.2The Universe version being a totally different design, and the Origins version being intended to match the movie version, even if it didn’t quite hit the mark perfectly. While I don’t think I’m quite done with Stargate just yet, I’m probably done with modeling actual stargates for a while.

Since last summer, I’ve been working on a new 3D model of the stargate in Lightwave, my third attempt. Since I last built a stargate model in 2006 (with small updates afterward), my skill as a modeler has increased, and reference material is far more plentiful. That includes behind-the-scenes photos, low-res but still useful construction diagrams from auction websites, HD home video releases of the movies and television shows, and, most importantly, high-res photos from Les Enfants de Mac Gyver, a group creating a duplicate of the SG-1 stargate setpiece using pieces of the screen-used version purchased at auction as well as their own copious research. There are many sections of this model where I simply wouldn’t have been able to even guess at what went where without their detailed and plentiful photos of their stargate being assembled, disassembled, and otherwise worked on.
