• 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.

MCX crash after adding platform

Messages

I have a rather large scenery project, and I need to add some materials as platforms.
When I did that and then call up the material editor and select one material, MCX will crash with an error message
If I do not define the platform materials, everyrthing works fine.
I'm using the MCX development version dated March 13th, 2021.

Any thoughts?

Hi,

That looks like an OpenGL issue. I'll try to reproduce it. All you did was add a platform and then select a material in the material editor?
 
Hi,

I just did a quick test where I loaded a model, then added some platforms with the auto platform function and after that I opened the material editor and clicked on various materials. I didn't get any errors when doing that.

So it might be something specific to your model, as it does not seem to be a general bug. Does the crash happen when you click on any material or on a specific material?
