• 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.

Seasonal Transparency Issue...

Hi Arno et al,

I'm having a problem with my latest ground textures. If I do an export with just the summer texture, everything is fine. Once I do the tweaks for the seasons, the image appears almost completely transparent. I have a mask built into the image. If I remove the mask completely - no alpha - the texture still appears semi-transparent.

Here is my code. Could you please have a look and tell me if there is anything wrong?

Thanks, Adam

Hi Adam,

The only error I could spot right now is the line

MATERIAL 1,0 ; summer

That is not valid, as you have no second material defined. So I guess it needs to be:

MATERIAL 0,0 ; summer

Not sure if that causes your trouble, but it is worth a try. Besides that it also seems you are exporting with the optimize option turned off in MakeMDL, that means you have a lot of nonsense commands (like the BGL_FTAG) in your code, I would advice you to export with optimize turned on.
