Yep... certainly -- follow the second link provided above & give a simple try with the Annihilator which is basicly a gathering of general parts from all the rest of Apocalypse reddishly futuristic fleet of vehicles.
At first, i was planning to split "everything" in small modular structures... but my 3d Modeling software trials expired & the free gMax can't make a compatible and valid directX (as per GC requirements) without some tricky acrobatics into conversion which actually fail 95% of the time.
I could fix a temporary and resizable "Egg shell" a few months ago (the four shiny engine Intakes at the front of Annihilator & others) by modifying the z'y' planes of a flat circular panel (the round Logo S99 structure, in fact)... but that process only gave me a single hardpoint (impossible to move, sadly) to attach it on default structures.
The problem is more about the exact shapes of the "blacky" windshields on any of these cockpits -- no matter how hard i try, there's nothing in the available GC stuff that can mimic the smooth angles and "bubbly" effect.
The trick, i believe, will be to decide where the HPs should be dropped on a final model for such vehicles -- but, let's see first what kinda mesh you can pull off for ONE ship, and then we'll discuss more extensive development for other ships; the fleet of Alien-UFOs for UFO:Defense are in fact terribly simple for being a bunch a rectangular type of "lego" assemblies. Basicly, the (already available) isometric tiles set would make any modeling attempts a LOT easier, including texturing since i already have those pngs ready.
Lemme know when you're done and if you need anything else - just ask! (We might as well *transfer* any further discussion about to the proper X-Worlds thread; https://forums.galciv2.com/172808, if you don't mind... easier to follow).
And, thanks in advance; you'll surely receive a whole 50% of the credits for X-Worlds FINAL version, count on me.
