• 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.

FSXA Jetway transparency problem caused by?

Hi,
I found something that might useful when you do glass jetway. I have made glass jetway and the interior inside by cloning the outside and flip the polygons. It looks just fine in static one.

Then I did an animated jetway and I found that there was a problem of jetway glass transparency. If I use transparent material (default transparent, z-test alpha, z-write), I cannot see the opposite interior glass wall. No mater I tried, changing material, changing the name of the texture to make it draw last.....etc, nothing changed.:banghead:

So, I set back and relaxed a bit and tried to figure out how to test what cause that.

I make a new model, called "test jetway" by making each box of glass jetway. I use the same material for each box and the whole thing comes out just fine.



The only different between static jetway and animated jetway is: the animated one has to combine every objects as one and apply skin to it.

So I try to attach all the boxes that I use for "test jetway". Then it comes out like this:



I cannot see the interior at all, either the glass wall or the floor!

So, I think attaching the objects together can cause problem with the transparency drawing order of glass material. Life would be easier if you leave each objects in the scene separately.

OK, now I know what cause that.
But I don't know how to solve.
Do you have any ideas how to solve that?

Regards,
Tic
 
Try leaving the transparent glass as a separate object, just linked to the rest. The transparent objects have to be drawn last for proper visibility through them.
 
I got it. I need to cut the polygon just only where the glass is and use another glass texture separately. The rest of the model is default opaque.
It came out nicely but it does not worth to do since it cause a lot of difficulty to make animated jetway since a lot of vertices have to be added up.

Link is not applicable to animated jetway. All the objects have to be combined together and turn to be skin and bone.
