• 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.

Help with DXT transparency in FSX

Hi all,

I'm having another disaster with Scenery design for FSX

Using DXTBMP to produce a simple texture with transparency in the alpha channel - in DXT1 format.

For example, If I make a plain red square and then adjust the alpha channel to have the word "red" in the polygon (black on white), I'm expecting to get a poly with the word "red" visible as a transparent 'cut-out'

But when I view the polygon in FSX, the alpha channel 'leeches' into the main texture colour, giving me the word 'red' in opaque lime green on a red background.

My project's at a standstill with this and the flickering texture problem, so any help would be enormously appreciated.

Thx
Chris
 
Try DXT3, apparently DXt1 does not work that well in FSX.

I have to admit to not having any real success with transparrent textures.

I've decided to give v3.5 a miss for the forseeable, have re-installed V3, which I'll use for modelling (since the transparencies work as expected there).

And am re-installing v2 specifically for:

a. Ground polys - via the API/'SCASM mod' route
b. Street/Apron lamps which I'll want to do at some point.

Dividing objects between BGLs in the scenery should ensure the best of each tool can be used.

Rgds,
Chris.
 
Chris,

Regarding transparencies in FSX using FSDS3.5... In the FSDS3.5 read_me file, users are directed to use a different name prefix for glass and transparent parts before you compile your model. Otherwise, FSDS3.5 does pass the transparent/glass part information correctly to makemdl, hence, the transparency/glass part does not show properly in FSX.

I am like you... I have decided to create ALL of my scenery objects using FSDS3.0, place the objects in FS9 and simply copy the scenery .bgl file, along with the textures and scenery placement file from EZ-Scenery over to FSX. Everything seems to work fine in both FS versions as long as I create the model objects according to FSX texture requirements. Even my transparent and glass parts show correctly. Of course, I use AFX for both versions of FS so the airport layout isn't an issue.

Much, much easier than learning some of the new FSX tools. I will have to change the way I do things for future versions of FS, but for now, all is OK.

Hope that helps,
Larry
