• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

A Comprehensive Explanation About Night Textures Please

Hi there,

Despite of many attempts in trying to find and also figure out how to add night textures, I have failed each time. I guess there must be something I'm missing but I don't know.

Let me make the issue a bit clearer. Currently I'm working on an airport scenery, Nicosia Intl (LCNC), which has been defunct for more than 40 years and as a kind of remembrance I decided to revive this "deserted" area. I have completed runway and taxi placement thanks to ADE and also SbuilderX, I have planted the required vegetation thanks to annotator in FSX SDK. So far all the arrangement are quite considerable. However, while approaching the final, I'm crashing almost every time and at same place. That is, I have almost finished terminal building through Sketchup, a huge amount of the texture mapping has also been achived. Few hours ago, wondering how it would look like, I exported the model as .dae and then imported it on ModelConverter X. All the textures and the structure seemed fairly neat. I converted the textures into .dds format through MCX' Mass Texture Editor section and later on prepared the .xml containing required info and finally compiled it. All of the textures have been copied to texture folder and .bgl to scenery. I got into the game and saw the builfing looking amazing except that it lacks the lights.
Suddenly, I began searching on google to learn how exacly the night textures are made. I have encountered several articles and discussions yet none was actually the solution to my problem.

Having reading some bunch of those written, I began editing the textures on Photoshop by adding _LM at the end of the textures that I'd like to illuminate. I decreased output to 25 on colour level section and used a soft brush with a proper bright colour. The outcome was exactly as I wanted yet after finishing this phase, I assigned each of the related textures with _LM end as night map texture on MCX, however on each try I had the error message telling me it failed to load the image. I have insisted on the process with almost all recognisable image extensions (.png, .dds"DXT3", bmp, jpeg...) however I got no result. I tried to convert them on texture converter, again the negative was what I got.

Well, I know I wrote a lot yet I really need help. Maybe all these processes I followed were not correct at all. Maybe, I really don't know how add night textures. Maybe the problem was about my manipulation style on Photoshop, yet there is one thing certain that I will sleep without being able to add the night textures on my terminal buiding.

What I request from those who have knowledge about the issue to explain me the whole process from the beginning, or even not that far, at least just after I export the .dae file. Please let me know what I am supposed to do. How can I get the most realistic results while editing the images? What have I been missing?.. I'd really appreciate the help and be thankful with all my sincerety. I hope to get a comprehensive and effective method from your experiences.

Thanks in advance.

Regards...

Ok, you need to place your night texture with the "_LM" suffix into the same directory as the day texture. Here is an example of a day and night texture for a fast food restaurant. These textures were derived from a satellite image service, like Google Earth and then edited to enhance definition. Please note how the non illuminated areas are quite dark, I normally use a layer mask of black or dark blue with 80% opacity, then the sources of illumination are brightened and exaggerated for the night image:

Next open MCX and import your model, open the Material editor. Click your texture on the left and then scroll down to the "Textures" section of the material properties window. Click the field for "Nightmap texture" and you will see a button marked "..." Click it and navigate to your night texture. Alternatively, you can type or copy/paste the file path into that field. Remember to export your model with the new texture assignments. This is my end result, not great but should work adequately as you pass over on final approach any time of the day:

Thanks a lot for the kind reply.

Finally I have solved problem that caused the inconvenience. The problem was that I was saving the night texture images as .bmp. Today I decided to save them as .jpeg and test on the MCX and the result was awesome. Later on, I converted them into .dds format so that the FS can read and render.

Please see the attachment for the latest outcome.

Excellent. Another technique that works well and conveys a little depth is to use transparent windows with an interior surface that projects the night texture.

Wow!

This one seems great actually! I once read about applying transparency on the windows yet I have no clue how to do it.
