• 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.

Textures cause faces to go invisible when normals appear to be ok.

Hi. I need some advice. I created a KCMH airport terminal model in Sketchup and put textures on it.
was able to export to a .dae file to import to ModelConverterX. Model looks great in ModelConverterX. I convert my textures to .dds and export the model as a .MDL. Then I go to LibraryCreatorXML, create a library, add my model to it and compile a bgl as input to Airport Design Editor 170. I import the model into ADE170, place the model where I want it and compile the bgl into Addon Scenery/scenery folder. I move the dds textures to Addon Scenery/texture folder.
When I load up FSX, most of the model is invisible. Some faces show, which makes me think I have normals (flipped faces) issue, but when I check the normals on the model back in Sketchup, everything looks ok.
Im stumped at this point. I have tried so many combinations of importing/exporting between sketchup/MCX/LCXML/ADE/, played with the textures per advice in this forum and nothing is working
I have attached the project. if someone could take to take a look at it and point me in the right direction that would be great.

Thanks
Chris

you have to check the .mdl in modelconvertex, with his textures,etc. in this way what you see is what you will see in fsx.
Should be a normals problem or some texture missing by law.

Hi Thank you for the reply. The model appears just fine in ModelConverterX. See image.

Hi,

In the file you sent all the PNG textures are missing so it appears completely untextured in MCX. The DDS textures are missing ramp.dds, roof2.dds, roof-mid.dds, and terminal_back_0.dds, so some of the terminal is untextured in FSX and thus becomes invisible (missing textures often cause those parts to become invisible).

Hope this helps,
 
I failed to include those dds textures to my zip file. They are present in the project on my machine. I am sorry. However. Your help led me to evaluate my textures and I found that 2 of the textures, (ramp and terminal_back_0) were converted to non power 2 images on the export to .mdl out of ModelConverterX for some reason. I wound up deleting those 2 textures, creating 2 new textures at 512x512, remapped the areas with the new textures in Sketchup. Export process again and this time I got the proper conversion sizes on export out of ModelConverterX. Continued the conversion process downstream and POOF! There it is in all its glory in FSX.
Thank you for your help.
 
Nice you solve the problem, and that you have posted the solution. good to know that no power of 2 textures could make invisible polygons. anyway MCX would indicate that in the log.
