• 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.

User Error or Possible Bug?

Hi Arno,

As per our conversation the other day I'm still having troubles with one part of a model turning completely transparent if I use "default transparent" on it.

Model is exported for FSX.

What I did was import the model, select the texture for the glass at the top of the building and switched on "default transparent" for that part/object.

Converted all textures to DDS DXT5 and then took the texture into imagetool and converted to 24 bit TGA, added a 128,128,128 gray alpha channel (want 50% transparency), then saved the file back to DDS DXT5 with the alpha channel.

In FSX the part of the model turns completely transparent. I'm wondering if I'm just making a newbie error or if I have found a possible bug.

Any pointers in the right direction would help :-) Having lots of fun with this...

Next stage is to learn how to apply reflection onto windows :)

Cheers,
Dean.
 
Hi Dean,

I would have to try this. It might be the default material settings are not "the best" for all conditions.
 
Ah, that would be very useful. I was planning to make a small test model myself.
 
Sorry I didn't get it uploaded yesterday, crashed out because I had to get up at 4am to get my belongings that had just arrived from Guam...

I've attached the SKP file here... The area in question is the greenish/turquoise/cyan part at the top of the building...

If you need I can re-do the previous steps i've done but i figured this is a good a start as any... ;-)

Thanks, I'll take a look.
 
Hi Dean,

I finally had a look at this. I had a little issue finding the polygons, since ModelConverterX also did not show them. After I reduced the "Alpha Test Level" setting in the material editor I did see the polygon. The same should work in FSX as well, the default value is too high for this kind of materials.

Maybe I should just disable the Z-test alpha by default. I will try to find out why I turned it on by default before :).
 
Hi Dean,

I have updated the tool now, it will select a alpha test level depending on the alpha value in the texture now. So from tomorrow this kind of textures should work automatically again.
