• 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 problem with separation plane

My task is to create REIL strobes, visible only from the approach side, like the PAPI lights, and activated by tuning a special frequency. I've made it strobing like i need by animating a light and it works just fine. Frequency activation also works just fine. But somehow I just can't get the separation plane to work fine. I use the same data string for the separation plane as i used for both PAPI lights and green/red runway threshold lights and it worked just fine there. In this case I just can't get it to work right. The strobes are disappearing from some certain angles but way not those angles i want to achieve.

Here's an excerpt of my asm file:

Code:

Hi,

That code looks OK to me. Do you have another transformation matrices before the check? I am not sure if they affect your separation plane as well. That's the only thing I can think of right now.
 
I have this right before the section i posted above. Not sure about what doest it stand for in the code as i've never worked with animations before, maybe you'll be able to get a clue.

Thanks!

Can you try to put your checks directly under the MasterScale_2 label? Then we know if the other transformations effect the separation plane or not.
 
I tried what you suggested Arno, but the problem is still there..

Except for the IFIN1 and SEPARATION_PLANE commands the code is as GMax made it for you? Or did you make more changes to the default code.
 
Humm, I am afraid I ran out of ideas in that case. It sounds like your approach should work fine.
