• 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.

Transparency problem - newbie here.

Just got the program working today. Kept getting an .ini error that was fixed by right clicking on the program and running it as administrator. So now after watching some YouTube tutorials I created my first scenery. I created a _B channel and I see the scenery in P3D but it is slightly transparent. I can see the underlying default scenery. I edited the .bmp file using Gimp and added a new layer, set it to white and made everything that I didn't want showing black, and exported it as a xxx_B.tiff. So what am I doing wrong that is causing it to be semi-transparent?
 
Hello:

[EDITED]

The Blend Mask must be a 8-bit gray scale image in a Alpha channel within a BMP, TIF, TGA, or PSD file, and defined as a "SourceFile" with an accompanying "Channel_BlendMask" parameter in a 'multi-source' FS/P3D SDK Resample INF file.


Alternatively it can be a 8-bit gray scale image with a entirely separate TIF file, and defined as a "SourceFile" with an accompanying "Channel_BlendMask" parameter in a 'multi-source' FS/P3D SDK Resample INF file.


If gradient transparency is used, the white values should not exceed more than 128 out of the maximum 256 values possible for the gray scale "steps" within the 8-bit format. :pushpin:

Beyond 128, scenery content (including autogen objects) on underlying layers may begin to show through to the top layer in FS/P3D at run time when scenery is rendered on-screen. :alert:


PS: You may wish to review the pertinent info in these threads:

...As well as the FSX SDK documentation:

NOTE: IIUC, the P3D SDK info and work-flow is nearly identical for Resample regarding custom photo-real aerial imagery BGLs:

...Also: I'd recommend reviewing these excellent tutorials (the last link is lengthy, but also extremely informative on multiple related sub-topics):

Hope this helps ! :)
