[NOT A BUG][MERGED] HUD COMBINER COATING

Me and my friend analyzed the HUD purple tint after seeing the latest video of the Hornet, by Magz.

We came to the conclusion that the HUD purple tint too dark is and not very realistic.

A couple of documents below.

On the first video, when the background is bright, the purple tint is almost gone, but when the background is darker, the purple tint is a bit more present, but still not dark as in game.

Those are all supers.. Different equipment different aircraft..

Not saying your wrong but may want to back it up with footage of the C model

Last two clips are from spanish hornets (EF18A+). Though its true that it has some different systems to the F18C, like the digital UFC (similar to the one in the superhornet)

I stand corrected. I wasn't aware of those.

The top video looks like it's tinted just right. Your comparing it from an angle that isn't correct. Let's just let them come out with it before we start picking out details we think are wrong...

Yeah, the models are different, but the point is the same. With current Deferred shader, it is really dark.

Edit - It seems that "angles" play a major role in deciding whether something is realistic or not.

I saw a video of the Blue Angles and asked why the right MFD looked different than in the sim....I was told that it was something called the strobe effect from photography. Like the guys have said....different angles make a huge difference.

I love the fact that we're discussing HUD tints. What a great simulation this is going to be.

Is anyone of the readers not hurt by my post?

It seems that you understood this post as a request to remove the tint, which is not what I requested and I didn't request anything at all, it is just something what we observed and I wanted to share the thoughts.

I apologize, I should have know its the angles. This is something new to add on the "list of excuses".

Strobo effect is when you have a strobo light that flickers very quickly.

That can happen with some very rare LCD panels that doesn't refresh whole screen same time but does the rolling update.

There are many other factors to count as well. Coatings is one of the most important ones that are wanted to be applied to all optics or surfaces. A most often you could see a polarization filter that will cut light two times darker, but you will get glare removed almost totally. Problem is that if you have other polarization filter that you rotate 90 degrees to other filter and light doesn't reflected at all or passed. And this is problem with polarization sun glasses as you can hit to that problem.

A HUD could clearly be used with polarization filter as you get enhanced contrast, but same time a UV filter would render blue stronger and remove the violet tint (ultra violet light).

What you can as well do is to use a other special anti-glare glasses that are placed on the surface of glass and it will direct the light straight front, but viewed more from angle the light doesn't reflect so glass turns black.

This is something you would want to use on the MFCD panels as the glare from surrounding light would be very minimal as it would need to shine to panel from straight front, so behind the pilot. It will increase the contrast but lowers your angle of visibility.

Then there are other challenging things like the camera framerate and shutter speed relation to refresh rate of the screen. And when you do that, you can get very fancy effects as the rolling shutter effect (sensor readout speed from bottom to top) with shutter speed doesn't keep up. With global shutter (whole sensor is read out at once) you can get other fancy effects, like this:

No man, do not take it that way! Great observation. We ALL want the sim as realistic as possible. Do not be discouraged from posting.

Looking at the videos posted, the HUD does seem to be too tinted for me. Taking the video posted by MurderOne there is a short moment where the camera is fairly in line with the HUD and still not as tinted (so it can't be angle alone, given that the tint hardly changes and the tint actually seems a bit darker at an angle in that video, not straight on).

On the other hand, does anyone have a video or photo of a real F-18 HUD being as dark as the DCS one? So far, I couldn't find any.

Purple tint isn't that bad but that second glass makes HUD much darker in half. This is really as it should be? Above photos ^ (nor last video on preview page) don't show that.

I don't know, but it looks like a different HUD style for me.

I agree, when I saw the videos, besides my jaw hitting the floor, I thought the HUD seemed a little too dark.

I was thinking DCS would get input from the real world Hornet pilots they have access to for development in order to get the HUD hue and opaqueness right.

I think its a pretty cool effect I wouldn't want to see it changed too much, I'm sure it would look a little different on your screen at home than on a youtube video etc.

Also I wouldn't trust photos of HUDs as the camera in question (especially if its a video cam) is probably not capturing the same effect your eyeballs would give you seeing it in person.

These semi-transparent screens tend to have some reflections in color when the external light comes in at unfavorable angle. This has to do how the wavelength-selective mirror is done: it is quite nontransparent to the green shade used in HUD symbology, but yet is rather naturally seen through by human eye with little dimming as much as I recall. Eye is pretty sensitive to the wavelengths purportedly selected for the HUD projection, therefore noticing little dimming of the background while improving the contrast of the display. But in certain angles, HUD certainly reflects a tint, apparently as a result of the ray distance of the layers changing with the angle.

Oh, and obviously I intended to mention, the view through the HUD is generally distorted in color towards purple, as it is not well-transparent to the HUD-symbology green. :)

^ this.

reflector tint do indeed get exaggerated by some camera sensor even when it can be barely recognized by human eye.

More work for the modders.

It's definitely a little dark, but give them some time to fix it. They have a lot of other stuff on their plate. IRL huds look the same as the pictures shown here of them- pretty much no tint (barely noticeable).

I agree tint is a bit too much from the videos we have seen but let’s wait and a see when it comes out! Also since when do hornets carry aim9 on any spot except wingtips.. I’ve never seen that before but i could be wrong. I know super hornets do not ever. Last request is more shake/buffet while pulling gs and at high angles of attack. It should be slightly difficult to read the hud during max performance turns.. this sim looks great so far.
