Pretty simple one, actually...

There's a problem with the gun sight as it's modeled: It's not accurate!

The whole point of these sights is that they project a nice little X where your bullets end up.

You model the fact that they get brighter and dimmer as you move your head away from head on (nice BTW), but in real life no matter where your head was the gun sight would still display the point of impact.

As it's modeled now the gun sight MOVES.

As one of those goobers who's constantly rubbernecking my virtual head around in the cockpit trying to get the ideal view it's frustrating that it doesn't work right.

In fact right now I put a little highlighter dot on my monitor to model this correctly

Having used those nifty little WW2 style gunsights in an actual real life fake simulated dogfight in a real life simulated ww2 plane (okay, it was Fighter Combat USA, and they use Marchettis) that's how they actually work. That's the whole point.

In other words, when my virtual head moves up but I'm still looking straght ahead the cross hair might get dimmer but it shouldn't move!

The community has already created some awesome guns sites, very accurate. Check out downloads page in HTC.

Well Lemur i thought that was the point of reflector sights.. they dissapear if you're not looking into the reflection .. that's what they do in AH ..

Duck, thats not quite correct. You have to move your head pretty far to the side of a reflector sight before you lose sight of the entire image. In AH, the instant you start to move your head, the image dims. The image of a reflector sight does not dim a great deal as you move your head on a well maintained sight with a bright bulb.

Lemur makes a valid and accurate point. The image projected onto the reflector glass is focused out to infinity not on the glass itself. What you have is an image that appears to float out way in front of the airplane and is hopefully aligned with the convergence of the guns. Also, the head shake you get when you move the flight controls would not affect the positioning of the sight. It would stay in the same place on the horizon no matter how much you shake your head. If you had to focus on a gunsight image two feet in front of your eyes in a real airplane, everything beyond the nose would be blurry. Not very conducive to hitting a fuzzy and doubled target 400 yards beyond your nose. Try focusing on your steering wheel (hopefully not while driving) while focusing on an object a couple of hundred yards away. One or the other is blurry and doubled. Reflector sights were designed to overcome that problem.

MigEater, you may not lose the image right away on a real Revi, but the alignment is screwed as soon as you move away from the centerline.

In a modern HUD (heads up display), your head position is very critical. If I move left or right even a little I'll see the gunsight (bombsight) shift by several mils. If I move it even more the data starts getting occluded along the edge.

Think of it almost like a pair of binoculars, if you shift your eyes you'll start losing part of the field of view.

That was the point of having a Revi sight .. it eliminated the paralax effects of a fixed mounted gun sight .. but you HAD to look straight through it.

It might be an argument on how far your head bobs around in the cockpit when you do high G manouvers -> I only did basic aerobatics so far (-1,5 - +5,5 G's) and i had my head hitting the canopy a few times (and i'm a small guy

) when i wasn't buckled in VEEERY tight.

Mig captured what I was trying to say pretty well.

Essentially the gunsight should get dimmer as you go off-axis BUT it should never move.

If your head is a 'foot' off to the right the sight might be quite dim but it should not have moved at all. The whole point of these sights is that they project the cross-hair at infinity. Ergo, head placement should have no effect on where the sight is suspended in space.

This is not the case we have now.

I didn't experience that with the Mk 8 sight. The image stayed steady out in front of the aircraft until I moved my head too far to the side to see through the combiner glass. How far out in front of the sight is the image of a Revi projected?
