• 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.

i've got a real puzzeler for you guys here ... for some reason when saveing as a DXT5 dds texture in photoshop this is what the alpha turns out like ..

i've saveing from photoshop useing the DXT5 ARGB/ 8bpp/interpolated alpha setting with no mip maps .. anyone have the slighest idea whats causeing it?? I've tried reinstalled the nvidia tools and that didnt do a thing :confused:
 
Have you got any transparent/semi-transparent areas on the texture? If so the exporter will put the level of transparency on the alpha layer, that's what the 'interpolated alpha' bit means. Try putting a background layer of solid white in and exporting again.

not really following what you mean?

It doesnt seem to matter what texture it is, the one above was from the spec map as it show the problem the best, but if happens with the diffuse and bump maps as well :confused: :confused: :confused:

It cant be the textures fault as its the ones from the a2a b17 paintkit, so its something in either the way i do things or a messed up setting somewhere. :(

No idea if it helps or not, but i've tried saveing from a 32 bit bmp file as well as the orig multilayered psd's but both end up looking the pic in post 1

Hi,

The alpha channel in a DXT5 file is also stored with some compression. There can be maximum 8 different alpha values per 4x4 pixels. So if you have a lot of variation in the alpha channel, you can see some compression.
 
There is something odd with Photoshop DXT5 alpha dds.

Try running the psd through imagetool.

I had some issues with this also.

well i was told there was an updated version from the one i was useing, so downloaded that and did a clean install of it .. works fine !! I did see the in the change log they'd fixed/added the layer stuff so i'm guessing thats what did it.

Problem solved! :)
 
Ah. Thanks for that. I'll check my plugin version.

Don't you use DXT1 when using alpha? DXT5 for normal no alpha?

Of course i don't use photo Shop. i figure it's something in the plugin.
