• 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.

XML draw-erase options?

Gents,
I've got a bit of experience with most aspects of design for FS, but gauges are still a "black art" for me... so please forgive the ignorance demonstrated below ;)

I am trying to replace a HUD gauge in an aircraft in FS9. The original gauge is written in C++ and makes use of the "no_static_blending" flag. Also, I'm fairly sure the aircraft designer has made the material for the HUD poly slightly opaque.

When I replace the original C++ gauge with any of the XML HUD gauges out there the gauge draws correctly, but does not erase/update the previous frames. So you can imagine it becomes a big, green mess when the gauge is drawn 30 times per second and none of the "old" draws are erased.

I guess this is because xml does not have the "no_static_blending" equivalent. Is that correct? If yes, is there an option in xml to explicitly erase previous frames? I've seen the "image_erase_always" development for FSX, but is there any workaround for FS9?

Thanks for reading this loooonng post!
