reflective aircraft body?

[D-ECHO]

Hi!
I have a little question about aircraft effects: Is there any realistic way to simulate the white-reflective paint on a usual aircraft body. Or is there any aircraft having such a configuration? I've tried many model-combined configurations but I couldn't find a one that looks good.
Regards
[EDIT]And how to activate the enviroment/cubemap

Code: Select all

<!-- Reflection environment -->
      <texture n="5">
         <type>cubemap</type>
         <!-- use this form for a cube cross -->
         <!--<image>Aircraft/Generic/Effects/CubeCrosses/blue_sky_big.jpg</image>-->
         <!-- END CubeCross -->
         <!-- use this form for a 6 image cube map -->
         <images>
            <positive-x>Aircraft/Generic/Effects/CubeMaps/fair-sky/fair-sky_px.png</positive-x>

         </images>
         <!-- END 6 image cube map -->
      </texture>

I only see where to add the map, but is there any value to adjust so it is activated (or a factor)?

[ausdkunst]

HAHAH do you also have the problem of white turning gray, light green turning dark green etc?

[D-ECHO]

Yep, I'd like to have something around this:

You see the reflection? It doesn't have to be dynamic, it can also be a static environment map, but I couldn't find a configuration to get this

[Thorsten]

Yes, that should be possible. A combination of a high specular channel combined with a weak environment reflection using model-combined-deferred.eff ought to do it. What's the problem you're seeing?

[D-ECHO]

For example my problem is how to factor the environment reflection?
[EDIT]The effect I use is

and I get a result of this:

but unfortunately I see no reflection of the cubemap

[Thorsten]

but unfortunately I see no reflection of the cubemap

I hate to point out the obvious but...

Code: Select all

 <reflect_map-enabled type="int">0</reflect_map-enabled>

first, you tried to disable it, second, it's called <reflect-map-enabled> (minus rather than underscore), so you didn't actually disable it but it's still off by default.

[D-ECHO]

So I have to set it to 1?

[Thorsten]

You have to set the correctly named property to 1 for the relevant shader block to be executed, yes. I didn't check whether everything else was valid though.

[D-ECHO]

Okay thank you I messed up grey and reflection Map. Thanks!;-)

[ausdkunst]

@D-ECHO please post up a screenshot because I want to know how it goes

[D-ECHO]

This is how it's looking atm. pretty neat but I need to find a way to make it much more white

[D-ECHO]

Okay, I tried a lot with different values, but I can't get it to be brighter than this

with this code:

Somehow, it seems to me the greymap isn't correctly read as, no matter whether I have it full black or full white, it looks the same. @Thorsten, could you help?

[Thorsten]

Code: Select all

<reflection-dynamic type="int">0.1</reflection-dynamic>
        <reflect-map-enabled type="int">0.000001 </reflect-map-enabled>

Seriously?

These are integer on/off flags, god knows what happens if you set them to floating point values.

What grey map by the way?

Did you try the documentation of the effect? It's a complicated beast in which the channels all have to follow a certain convention and flags have some mutual dependency. For instance, if you specify four lightmap channels but leave the lightmap flag to off, you're not getting any because lightmap channel function requires lightmap on. If you request any normal map but don't supply tangent and binormal vectors, you get a dark aircraft (or worse, a crash).

The documentation is here: https://sourceforge.net/p/flightgear/fg ... mbined.eff

Thank you!!
So I set everything accordingly to the docu:

        <reflection-dynamic type="int">1</reflection-dynamic>

                <negative-z>Aircraft/Generic/Effects/CubeMaps/real.fair-sky/fair-sky_nz.png</negative-z>
            </images>
        </texture>
                <reflection-rainbow type="float">0.1</reflection-rainbow>
                <reflection-fresnel type="float">-1</reflection-fresnel>
        <ambient-correction>0.5</ambient-correction>
    </parameters>
</PropertyList>


Now it's reflective and somewhat bright, but it's a bit blue-greenish, is there a possibility for a color-correction inside the effect?
