Maybe you are right, Torsten.

@ludomotico

If you wanna follow this path, please. Let me know before.
I have to apply the left side mirror and close a hole.

@primtala2

Maybe you are right, too.
I got the sign from a photo posted by the owner of this thread, @gsagostinho (who is missed somewhere, without a GPS).

I can purge it. But @ludomotico is leading the changes now. If he says to remove it, i will remove.

Anyway, you can remove it yourself, if yo want.
The texture file is COLOR_something.png, into the Models folder.

Cheers.

LIGHTS and SHADOWS

abassign wrote in Wed Feb 11, 2015 8:08 am:I think we can make the two illuminators domes softer and semi-transparent, as was done in DHC6 project.


Can you check how the lights are rendered when rembrandt is enable in the DHC6 ?

Here, i am facing the (guess it is a traditional one) dillema of getting good shadows or getting good transparencies.
See these referece pics :

As you see, there is no texture semi-transparency when rembrandt is enabled.

Don't know if it is being fixed or not.

@ludo

- Joined the Manual and the bag into one LeftBag object ;
- Changed the name into xml, to reflect this change ;
- Aplied the mirror to the right side and closed ;
- Changed some incosistent names, (doorhandle, windowlock etc, to "object_left", "object_right" way of naming) ;
- Applied the mirror on the right door ;
- Leaving the door. The only way i see is to remodel a new door. I will not waste time on this for while ;
- I make some dirty in the main glass. But it doesn't work on rembrandt. Lost a lot os time trying to figure why, until realize that rembrandt views the trasparency as 0 or 1. There is no semi-transparency.

The files are in the same place.

I see these changes as possible finished. If you want submit, it is with you.

Going to seats, but tomorrow.

Cheers, boss !

See these referece pics :

There is an effect to manage this: model-transparent. Just add these lines to c172-detailed.xml:

Code: Select all
   <effect>
       <inherits-from>Effects/model-transparent</inherits-from>
       <object-name>navlight_left</object-name>
       <object-name>navlight_right</object-name>
       <object-name>navlight_back</object-name>
       <object-name>strobe1</object-name>
       <object-name>strobe2</object-name>
       <object-name>navlight_back</object-name>
       <object-name>BeaconOffX</object-name>
   </effect>


I have added these lines after the already existing comment "<!-- Transparent Surfaces for Rembrandt rendering -->" ;)

Image

In Rembrandt, an object with this effect will use the alpha channel but won't cast any shadow (afaik) Be careful with transparent objects in Rembrandt because there many appear problems with the order surfaces are drawn. Check this thread for reference: viewtopic.php?f=5&t=22707

This is the only change I've made today, so I'm not uploading again my files (they take a while, my connection is not the best)

Also, we must configure the new effect to have shadows at least for the exterior model in ALS. This would be a job for the next week, I'll be flying this weekend!

Hi all,

Sorry for my late reply, I've been busy this last week. I created a new image for the vac gauge with the same resolution as before (128x128); it is very simple but I hope you will like it (or find it acceptable). It is based in the gauge picture that ludomotico had previously shared with us. Let me know if this works.

VAC:

VAC without the needle:

Needle only (background is transparent, so the white needle is invisible due to the forum's white background):

Thanks! This texture looks superb! I will add this texture to the aircraft, but I'm afraid yo'llu have to wait until Sunday.

I am glad to hear that, ludomotico! I am glad I can contribute a little bit somehow :) And there is no rush in adding it to the aircraft.

Take care!

abassign wrote in Wed Feb 11, 2015 8:08 am:Notice the light on top of the rudder, is off center


Hi there, abassign.

Today i would give some roundness to the seats. But as the change in the beacon pos appears to be only a change in the xml file, i decided to do this first.

The bad news is that the UV mapping was displaced :

Image

It is a single plane always facing the camera. But in the specific case of this light, it works only partially, because of the tail acting as a obstacle.

I bended the plane a bit, to avoid this.

Image

Then, i recentered the UV map and centered the light pos into the median point of the beacon.
The result is that the tail does not obstuct the light, independent of the angle.

Image

Image

Image

It needs yet put some transparence on the beacon itself when using rembrandt.

About the shape and alpha of the light, i will see what to do.

But at least, it is centered now.

Cheers !

Hi all,

I just did some very small tweaks on that gauge (better layout of the text + some smoothing of the edges). Please use this newer version:

I took the liberty of creating the aircraft shadow (ALS style)

If you want to incorporate it into your project please feel free to do so.

Here is the code

In Aircraft/c172p/c172p-detailed-set.xml (about LINE 120) add
Code: Select all
<autopilot>
      <path>Aircraft/c172p/Systems/gearAGL.xml</path>
</autopilot>


Create Aircraft/c172p/Systems/gearAGL.xml
Code: Select all
<?xml version="1.0"?>
<PropertyList>
   <filter>
      <type>gain</type>
      <gain>0.3048</gain>
      <input>/position/altitude-agl-ft</input>
      <reference>5</reference>
      <output>/position/gear-agl-m</output>
   </filter>
</PropertyList>


The path to the shadow code goes at the end of Aircraft/c172p/Models/c172p-detailed.xml
I put it as the last block of code before the closing "</PropertyList>"
Code: Select all
<!--  ALS ground shadow  -->
<model>
   <path>Aircraft/c172p/Models/Effects/shadow.xml</path>
</model>


The shadow configuration code goes in Aircraft/c172p/Models/Effects/shadow.xml
Note: The "Translate to ground level" code block remains commented out. It would be used for the non-ALS shadow.
Code: Select all
<?xml version="1.0" encoding="UTF-8"?>

<!--
Copied from the Boeing 737-100
http://helijah.free.fr/flightgear/hangar.htm
embaranger@free.fr
Fix required:
when the aircraft is flying at a high/low pitch or is rolling over far,
the shadow seems to disappear into the ground.

Thanks a lo! I think it is looking nice indeed, thanks for implementing the textures.

Which buttons? If there are some textures missing, let me know and I can try to create them myself, ok?

Take care!

The experts think we only need frame rate level property rule instead of the fdm autopilot rule.
So here is the change.

In Aircraft/c172p/c172p-detailed-set.xml (about LINE 120) add

<autopilot>
<path>Aircraft/c172p/Systems/gearAGL.xml</path>
</autopilot>

Instead use this
Code: Select all
<property-rule n="101">
       <name>gear_agl-m</name>
       <path>Aircraft/c172p/Systems/gearAGL.xml</path>
</property-rule>

More fine tuning.

Need to remove the "offsets" from Aircraft/c172p/Models/Effects/shadow.xml
<offsets>
<z-m>.45</z-m>
<pitch-deg>.50</pitch-deg>
</offsets>
they are not needed for this implementation.

and then in Aircraft/c172p/Systems/gearAGL.xml change LINE 8 "reference" from 5 to 6 (if the shadow needs more distance from the ground add to the reference number)
Code: Select all
<?xml version="1.0"?>
<PropertyList>
   <filter>
      <type>gain</type>
      <gain>0.3048</gain>
      <input>/position/altitude-agl-ft</input>
      <reference>6</reference>
      <output>/position/gear-agl-m</output>
   </filter>
</PropertyList>


Also, if one of you talented artists want to touch up the shadow.png texture. It was a real hack job on my part.

All your modifications are really outstanding.
