• 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.

Rays from my lights?

I've almost never used effects, my airport lights for FS2004 were always a 'photo' mapped to a plane. Since this doesn't work with FSX (it doesn't allow a separate day/night alpha) I have been redoing my lights as effects. This is fine for most, the 'fuzzy ball' lights work ok generally.

However I'd like to make something more impressive and larger, with rays.

Here's a pic of my old-style lights, showing the effect I'm trying to create.

Place your intended "rays" as an image in a .bmp file, and code your .fx file to use that as the basis for rendering the effect.

Open the fx_2.bmp file and see how there are many examples of such "rays" that're used by all the lights in FSX. The area circled in red is what is used for the fx_landing.fx file (landing and taxi lights) for example.

The other, single image shows one we made for our custom "strobe lights" effect file.
