• 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 is there a white area covered after the BGL of natural scenery is imported into P3D?

he TIFF I downloaded has no white area, but after converting it into a natural scenery BGL and importing it into P3D, there is white occlusion. How can I solve this problem?
 
I think you did not set the no data value correctly when making the BGL file. You need to set it to the value that your image has for that area.

hi arno， Where should I set it? I looked in the manual and the video and found no information about it
 
I assume you used the scenproc step to make the photoreal? The no data value is one of the arguments you can provide. Check section 10.7.9 of the manual, it's the 5th argument.

hi arno

Do I set the value to draw the red line?？

hi arno |-1；-1；-1| |0；0；0| |1；1；1| I have tried all these numbers, but none of them can solve the problem. Which value should I set?Do I need to adjust the“maskFilter”, but I don't know what to enter in this.

-1 means no no data value. Since it shows as red you would set it to 255;255;255.
 
hi Arno，It seems to work after adjusting to 255, but why is there this red line at the edge after adjustment?

Do you see that in the sim as well or only in the tmfviewer?

Sorry, what sim are you talking about? I imported the exported bgl into p3d, and then I saw this line. But I don't see this red line in TimfViewer, and this red line only appears at the edge of the water.
 
The screenshot looked like the tmfviewer, that's why I asked about the sim.

Does your water mask maybe extend outside of the imagery (so into the no data area)?

o_OMaybe yes, I blurred the edge of the water. I will try it now after removing the blur value！

I also want to ask, why can't the tf2 file be opened when it is opened again? Is it going to be remade?
 
You should be able to open the TF2 file again in the editor afterwards. What kind of error do you get?
 
I'm afraid my Chinese is not that good, so I can't make any sense out of this error message.

I just double checked that I can save and open again a TF2 file that contains a sample image and some vector data. I do not get any errors.

Did you leave the TF2 file in the place where you saved it? Beause there are a TestImages.tfz and BackProjectSamples.tfz file that belong to the TF2 file.

Those Chinese prompts are: An unhandled exception has occurred in the application, and if you tap "Continue", the application will ignore this error and try to continue. If you click "Exit", the app will close.

The object reference is not set to the instance of the object 。 And I put those three files in one folde
 
Did you move any of the files (the TFC itself or the images or vector data) after saving the TF2 file? I will double check if that can result in an error.

hai arno，I just tested it and even if I don't move any files, it still reports an error like that
 
That's weird, as I did the same test here without issues. Could you maybe send me your files to test?
