• 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.

ScenProc Unhandled exception

ScenProc generally handles ok and stable except Texture Filter Editor. I can access the tool and add an image but the image never shows in the middle (only shows as a thumbnail on the left) and once I click the image I get an unhandled exception as shown in the screenshot below.

I did some research but it looks like nobody else faced a similar error so it must be something I am missing or doing wrong. Anybody knows the solution of the issue? I am running latest scenproc including the update.

Thanks

Hi,

Which format did you use for the image you loaded?
 
Hi Arno,
I tried tif, bmp, jpg all give the same error. For tif and jpg when I hit Quit it quits instantly (scenproc closes) however, in the bmp case, when I hit Quit, I get another 2 times another unhandled exception saying this time:
"The process cannot access the file 'Top Left.bmp' because it is being used by another process."

Thanks
 
Hi,

Did you try geotiff as well?

I'll try to test here with some of the formats you used.
 
Hi,
No I didn't try geotiff as I don't have a program installed atm to export it in geotiff. Do you have a handy geotiff image to try and see if that works without the exception? Which program is best to use to create the geotiffs?
 
Hi,

I checked and at the moment only loading georeferenced TIF files works. Since I always use GeoTIFF myself I never noticed other formats have issues.

What I normally do is use my GIS tool to save samples out of the images used for the imagery. Then I can tune the filter with those samples and later run it on all the images.

I'll try to find out why it doesn't work with other images.
 
So since the issue is identified I will stop trying to figure out why it's not loading the image and will get to know the workflow for the geotiff format.

Thanks
 
I'll try to fix this bug somewhere in the coming days, as the editor should of course work with various image formats.
 
Thanks Arno,
Just another question that comes to mind - if the editor uses plain image formats that are not georeferenced, how will scenproc know the position of the AGN to extract to? Is there another way to set coordinates if you are using the texture filter editor approach?
 
Hi,

The final detection is done with the DetectFeatures step. This step uses geo referenced images, read with the ImportGDAL or ImportINF step.

The texture filter editor is only used to tune the filter that the DetectFeatures step uses. So the texture filter editor doesn't need to have geo referenced images, as it does not create the actual polygons.
 
Hi,

I have found and fixed the bug in the texture filter editor. So in the next development release you will be able to load non-georeferenced images as well.
