• 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.

Why Custom Aerial's gradient edge blend cannot render correctly?

Hi guys, I've managed to import google satellite map via QGIS and tiles2bing
But it has a big problem

In photoshop, I've already managed to create transparency in canvas

But in game, it still shows this hard edge. The custom aerial image cannot blend with default bing map...

What could possibly be wrong?
Must it be saved in 16 bit? Or specific format other than PNG?

This is the SDK example... 32 bit PNG:

Hello...
I tried to change the bit depth to 32bit but no help. It has a strange all-area transparent effect together with very hard edges.You see I've made sure that transparent area is really at zero value

Which is more strange is that in the document of the SDK I found this

It said it requires 16 bit PNG
This is confusing....

Did you try it as 32 bit?
If you're having trouble saving as 32-bit PNG, you can save a 32-bit PNG using photoshop's save for web feature. Choose PNG 24-bit and check the transparency button.

Yeah I tired to save it directly through save as.
But fails.

Cannot get this right....
So just for clearing, should I erase border pixels to make them transparent and create a alpha channel (rather than only lett the RGB control translucenty) and then save? I didn't see this in the video tutorial
