DC-4 Skymaster

Hello,

Another project launched for 2025-2026, concerning a port in native FS20/FS24 of the DC-4 Skymaster from the 3D model created by Flight Replicas (P3Dv5 version), of course with the authorization of Mike Pearson.

Indeed in October last year I was very surprised that no one cared about the DC-4 while all eyes were on the B-24. As apparently it did not seem to interest other developers, with another eminent developer from SOH (I leave it to him to announce himself ;) ) after exchanging a few messages we asked Mike if he agreed.
This one was delighted to see that we were paying attention to 'his plane', he gave us his agreement on November 7th.
After some preliminary works to exchange datas between us and to familiarize myself with this plane (I have never worked on a commercial aircraft) I was able to organize quite quickly a working project from the P3D version of Flight Replicas.

Not wanting to have too many projects at once, the current version of the PBY has been delivered before the announcement of this project, according to the planned schedules and now I can come back entirely or almost (I will works also the A-26 in the same time) on the DC-4 Skymaster.
Last week another person came forward to join the project. Before accepting his help, I had to finish the current study and the few essential works to be sure before announcing this project.

This aircraft should be primarily built for FS20, in native mode, trying to take maximum advantage of the possibilities of this SDK. we still keep in mind the possibility of being able to make a native FS24 version but it will mainly depend on the SDK ...
I would try to use what I learned on the PBY to create a project tree that will allow for several variations, but at first I think it’s better to focus on one version and then see. Maybe we will not reach the level of PMDG but I hope that the result will please a large number of people and as the welcome that was made to me on SOH exceeded all my expectations, I think that this plane like the A-26 Invader should logically be hosted on SOH’s Resources :cool:

Today this preliminary work is more or less finished and also because some people had guessed that I was working on this aircraft so I can present you some images of the current state.

Exterior file with for textures the old P3D textures simply transformed into a PNG (textures and UVs will be modified to be PBR and 4K at least)
The stairs (accessories file) are linked in this file.

A other view to see all details included in the Mike modelization. Some objects are animated (yokes and some levers) but a lot of works is needed to obtain a "good VC".

To be able to create the work files, I started from Mike’s MDL (interior & exterior) files that I transformed into glTF/bin files with the developer license that Arno Gerretssen provided me. These files were then imported via the plugin developed by FlyByWire and transformed into 2 blend files: Exterior.blend & Interior.blend.

The exterior model having a "simplified interior", the latter will be isolated to serve as Interior_LOD01 and the exterior accessories will be the subject of a separate file. The project has 5 blender files:
- one external
- one interior (LOD00)
- one interior_bis (LOD001)
- one accessories
- one called Reference file which is linked with exterior + interior + interior_bis + accessories

Using the Link function of Blender (the same exist on 3DS Max) from a Reference file permit to organize the modeling work more efficiently. Thus it will be possible to works on each of these 4 files (textures or UVs or modeling) and to reintegrate the various updates within a reference file (or main file) in an instant.
All the elements of a Linked file appear in the file that calls them but they are frozen so we cannot modify them: security !
When one updates one of these 4 files, all intermediate developments are instantly updated in the reference file.

I still have a little work to do to distribute and rename as usual all the objects of each file so that the work is easier afterwards: an explicit name is easier to find than a generic name that was automatically given by MCX during format conversions.

The version of Blender used is Blender v3.6.23 (last revision of Blender 3.6 LTS) and the export plugin from Asobo : v1.3.3.
 
Great news!

Keep in mind that after SU4, many users who were splitting time between 2020 and 2024 have made the move over to 2024 full time, so it may be a better use of your time to start focusing on a native 2024 version rather than 2020.

Steam usage still show rough 50/50% usage between MFS2020 and MFS2024. So this statement is a bit off with the facts. ;-)

Hello,

To be clear about the objectives of the project:
- the two current team members have agreed on an FS20 version initially while reflecting and selecting technical choices compatible with a possible FS24 version (choice that is not ruled out but simply under study). Bazzar explained his point of view on this subject a few weeks ago and as a developer, I completely approve him because he is an expression of common sense.
- I have on other projects accepted too quickly extensions/functions that made ongoing projects grow too quickly, making them very difficult to manage, therefore we start with a single model while keeping the possibility to easily add other versions or/and extensions.

The code I developed for the PBY has been made modular and the XML files have been grouped in a single directory. Each variation calls two basic XML files and then depending on the specificities of each variation, others are called to respond to special functions. This method was successfully initiated on the Stearman and then on the PBY, so there is no reason not to repeat it for the DC-4.

To resume: our choices are to progress slowly but surely without "closing the door" to a FS24 version and/or possible others variations. I can not be more clear to answer to ours questions.
--------------------------------------------------------------------------------------------
To return to the project, some must have noticed that the textures of the lower fuselage are black.
It’s not a mistake but simply these are just P3D textures that have been transformed into PNG and these textures are transparent on all the black parts.
Therefore, it will be necessary to review all the textures to see the differences in texture processing between P3D and MSFS and adapt them on a case-by-case basis; the objective being to have 4K and make maximum use of the simulator’s rendering engine.

Theses textures contains an Alpha channel, so with Gimp :
- select a background texture like a "light grey",
- click RMB on the calc,
- remove the Alpha channel in the contectual menu,
and saving the texture permit to solve the problem.

The DC-4 for P3D use also specular and bump files so to obtain the others files needed for a PBR aircraft, I use ShaderMap 4 Pro (inexpensive payware) which allows via an option to create all the others textures: albedo, displacement, ambient occlusion, roughness and metalness.

@brian,

I hope I wasn’t "too harsh" in my response (my native language is French): I was not my aim.
Intrigued by these models that I hadn’t noticed during my tests of the DC-4, I decided this afternoon to work a bit on the subject
I just "processed" quickly the interior models of Carvair and Tanker models to see under Blender the main differences compared to the basic model.

The Carvair with in red circles, the main differences that I see: :

The Tanker/FireFighter

This preliminary work is not lost, it will allow me to think about the best way to integrate these different VC and also the external fuselages into the project.
I keep theses files in a "backup folder" to work on them after we succeed to obtain an acceptable basic model.

Tanker cockpit looks awesome. Even a box mounted on the top of the panel to mount a garmin 430 that talked to the nav mode of the AP would be awesome:)
 
I'm delighted to see this announcement! I think this project has the potential to turn into something pretty special.

I'm glad you are keeping the door open on a native 2024 version too. I think my next project (am kicking around a couple of ideas) will be converting something to a native 2024 aircraft. However for the foreseeable future I'm busy on the B-24 as we still have plenty to do.
 
As already explained by Got Friends I believe, there are several ways to design a native FS24 aircraft.
It can either:
- check the file structure that we know from FS but to be compiled with the FS24 SDK
- be developed using a hierarchical structure of several 3D files, called "modular structure" while being compiled with the FS24 SDK
- be developed in such a way as to be able to check the essentials pointsfor the "career mode" with today’s FS24 SDK.

An FS20 aircraft that behaves correctly under FS24 and supports a compilation with the FS24 SDK is the easiest way to achieve this :cool:
Still, it cannot be done if you do not have the sources of the plane (I am talking about a complete aircraft and not about adding a 3D model to an existing plane)
 
Also, currently career mode is only supported for Marketplace aircraft, so supporting it would be a wasted effort for a freeware plane. So using the old structure but compiling for FS24 makes sense here.
 
I am super excited that you are working on the DC-4. While many here tend toward military aircraft, hence the support for the B-24, I tend to do much more airline flying that military flying so was disappointed that the DC-4 took a back seat to the B-24.
 
I was quietly hoping someone would show the DC-4 some love.

Since I don't contribute to 2020 (and reading about how much work Lagaffe has put into his various creations I don't think I will be) I didn't say anything as I don't want to be one of those members who ask for a lot but don't contribute a lot but I am definitely doing a quiet little happy dance in front of my monitor.

Merci beaucoup Lagaffe
 
I love the selection of aircraft subjects you have slated for 2026, Didier and I think your plan to build to 2020 first with an eye toward FS24 is a good one, for the reasons you have specified.
I'll be following your progress as usual and look forward to flying these planes in the coming year or so - I also think you are wise to 'pace yourself' as you say, with one variant of each to start off with.
