SUDDENLY I am reminded of why I haven't been here in half a year, and why FS2 Modding fell off the radar for me.
Why? Because it's a pain in the ass.
Okay. So I have the Deimos. I open it up in PCS2 2.03 Stable with collada. I select the the destroyed engines and delete them. Then I copy the okay engines, and rename them to engine01-destroyed for example. And what happens? I open it up in the mission, and for some reason the aft destroyed engine relocates itself to the middle engine, and sits there crashing through everything. And in the rear some random piece of debris juts out the aft of the ship and for the front engine, well I didn't even bother looking. I don't know how I can copy an engine, and get a different engines debris, and get a piece of ship debris, and whatever else.
So THEN I think screw PCS2, I'll export the model to .dae instead and bring it into Maya. I do the same thing, deleting the destroyed, copying the main, and getting rid of any extra information. So then I export it and open it up in PCS2. And now, suddenly, the "Damage" texture has replaced every other texture so the ship is just covered in damage texture. What the hell???
I mean seriously. This should not be hard. All I want, is to remove the engine glow to show the ships starting up. Something so easy, always has like problem after problem after problem to deal with just to get it to work. Aggravating.
I think what I'm going to do is just take the retail models and use them instead because I know those will work. Hopefully the updated maps for the retail models are still in the mediavps.

EDIT - Oh and something dumb I've noticed. Engine glow does not correspond to engine integrity. It corresponds to whether the ship is disabled or not. If I take a Deimos, retail version, or whatever version. And disable all its engines, the engines do not glow. There is no "visible thrust". But, if I repair just one of those engines, all the engines light up! If I repair Engine 02 but don't repair Engine 01 and 03 it doesn't matter, because by repairing 02 all the engines will look functional. Kinda goofy. I was trying to start up my ships engines in a random sequence and they all kept coming on at the same time and I couldn't figure out what the heck was going on.
