• 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.

FSX Weird artifacts in the VC after modding the mdl file

I just posted a thread a few days ago about adding landing/taxi lights to the FSX maddog. That went pretty well, but I have a bigger problem now. When I export the VC mdl with MCX, I get intermitent artifacts in the cockpit, as shown in the picture. Any ideas on how to solve or prevent this while exporting, please? It doesn't seem to have anything to do with the models I merged with the VC, because I still get the same random artifacts if I simply load the vc mdl in MCX and export it back straight away. What a shame, the landing lights look great now, but this is unusable as it is. Thanks.

Do you see this issue when you import this model into MCX?

I don't. The artifacts follow the viewpoint. At some point they go away when I move the viewpoint far ahead the cockpit in FSX, but only while looking in the opposite direction of the VC.
It's like something breaks the rendering of the VC. If I fire up FSX and change windows to something else, the artifacts are there right at the start of the flight. If I don't change windows, it takes a while but they eventually start. It's very weird. I think it's something to do with this particular aircraft. I will try removing random model parts from the mdl to see if one of them is causing the issue, but there's a lot of them. Dammit, all the work for nothing 😕
Nevermind, I found the offending element in the tree! It's the one containing the models for the yokes, windows, tiller and rudder pedals, and I can live without those, but I'll try to narrow it down a bit more. Man, for a minute I thought I'd wasted my time here. Phew!
