Does destroying UFO equipment affect resource outcome?

A good way to deal with UFO is to open the door and throw in a bunch of rockets and grenades. But this way I destroy all equipment onboard. Will it affect the number of resources gathered after the mission? If yes, is there a table describing how much resources I get from certain equipment?

I know that I loose all stuff that aliens were keeping in their pockets, the question is specifically about equipment.

Yes, destroyed power sources and such reduce your loot, which is Dependant on the intact sprites at the end of the mission. I'm not aware of any chart detailing the specifics.

The only props which carry resources and can be damaged are:

Engines (both the small and large ones);

UFO Beam Weapon (the one-tile red and black prop which you find usually on an outward facing wall);

UFO Torpedo Tube

UFO Power Source, Alenium Reactor and Fusion Reactor;

Anti-Grav device;

Hyperdrive; and

Singularity Core

So all the things like the navigation chairs and computer consoles don't matter at all. It's also worth nothing that a lot of the resources carried by UFOs are held in indestructible props so even if you destroyed everything you possibly could you'd still get some resources out of it (and if it's a landed UFO that's probably more than you destroyed).
