I have been trying to enable cockpits in BP: AoA and ran into a problem when testing them on Erynies.

It looks like the glass suddenly become visible on both sides instead of just outside, it did not happened when I enabled cockpits some time ago and played many campaigns with them.
It seems that it's also similar to the problem described here: http://www.hard-light.net/forums/index.php?topic=58443.0
AoA did not altered Erynies model in any way, nor it's textures.
I had experienced this problem on Steve-o's fighters several times before (this time XA on versions, in all ther incarnations, including originals, BP versions and my own reskins), so this may be either a common model issue or a code problem.
I've tested it on 3.6.10 build, the issue presisted.
So far, I confirmed it on Ulysses, Ursa, Herc II and Erynies, using only empty mission and mediavps.
If I made a wrong choice when chosing the board to post it on, feel free to move it where it belongs.

Yeah, the background gets reflected on the inside of the cockpits as well now. I personally have no idea what causes it.

[Colonol Dekker]

Well at a guess i'd say somewhere, there's an environment map for the Erinyes glass.
 
Might be worth checking.

[Zacam]

gold-glass.dds does have a -shine map for use on the outside. Always has.

[Dragon]

Yes, and that was not a problem.
Erynies is an usefull example, as it shows that entire glass showed up, not just the shine map.
With the solid orange plate blocking the entire view regardless of ship's position it's fairly obvious.
Is there any chance to get it fixed?

[Zacam]

Uhh. Again, the same texture is there that has been there since at least 3.6.8.

[Colonol Dekker]

Shine and environment are different though aren't they? 

[Zacam]

ENV is based off the -shine and requires -spec in use to use.

I don't think it's a MVPs issue, but rather a change in the way the engine renders things.
This started surfacing along with 3.6.10. In 3.6.9, one-faced planes would only show up on the correct one side, but for whatever reason, after 3.6.10, it gets rendered on both sides. So now we have reflections on the inside, and the older versions of Steve-O's fighters (with the solid cockpit) becomes solid, where I never had that issue before 3.6.10.

[Zacam]

I wonder what it does under fixed render pipeline then.

As it might (though I could be wrong here) be related to the way the shader system is doing things.

Would that be possible to revert that change?
It makes usage of cockpits practically impossible.

I used a hack for Wings that gets around this, taking a version of the model with the "invisible" texture for the glass and using it as an external cockpit POF.

[Fury]

That's an ugly hack we shouldn't need. Is source of the problem in fs2_open? If yes, this topic probably needs to be moved there.

I also wanted to use that, but the rest of the team decided that it would be better to fix the problem than to get around it.
And yes, it's an FS2_Open problem, seemingly dating back to 3.6.10 nightlies, in which it started to appear.
I guess that moving it may get attention of the coders, who should be fixing such issues now.

Try turning down your launcher flags dealing with spec. A lot.

I think it was -spec_static. I used to have solid mirror canopies on all my fighters because of a spec_static of like 3. Not sure if it'll help in your case, but it's worth a shot.

How is there any reflection at all?  Is the inside of the glass mapped somehow?  If it's not mapped it shouldn't be showing up.  If it is mapped and has some sort of shine applied to it, it's going to reflect.  Maybe the maps were always broken and the engine fixed something so that they reflect as they should now?  Just throwing some thoughts out there.

[Dragon]

I think that it isn't mapped, so it should not show up, jet it does.
That's why I'm asking SCP to fix that.

[FUBAR-BDHR]

Just tore apart  the Ery from the MVPs.  Absolutely no inward facing normals on the polys that make up the cockpit glass.  Don't appear to be any on the helmet visor (which the eye point may or may not be inside) either. 

[chief1983]

I wonder if the specular effect itself is visible from both sides of a surface.  Not as if it was mapped from the inside, but the effect generated on the outside via the specular shader.  That'd be odd indeed, wouldn't it?  But perhaps someone made this change specifically for glass surfaces.  Does this happen with GLSL disabled?  I'm curious if it's a shader issue.  Even still, it could be a bug in the GLSL code itself and not the shader.

[FUBAR-BDHR]

Well I know you can see reflections on the glass from the inside.  For most things it's kind of cool but for things like maneuvering thrusters it's not quite so much a feature.  You can't see the thruster itself but you can see the glow it causes so there might just be something to that.
