• 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.

DDS Specular Texture Convert

Hi Arno,

Been playing again with MCX this afternoon and having a blast prepping some buildings and have a suggestion to help work flow.

As I was adding some specular maps from TGA source files and converting them to DDS files I noticed that the texture tool in MCX defaults to DXT1 in the conversion. With the way the specular maps are it results in a dithered specular texture and alpha channel.

Wondering if it's possible in future to have anything listed as *_specular*.* converted to DXT5 format DDS? This would really help with specular mapping for buildings in FSX...

Maybe a preferences option for what type of .DDS output format for each _LM, _SPECULAR texture etc would go a long way in making the process faster in prepping models for FSX...

Just a suggestion ;) Now off to test fly around the building...

Cheers,
Dean.

Hi Dean,

Currently the texture saving logic is supposed to work like this:

No alpha channel -> DXT1
Alpha channel & FS2004 -> DXT3
Alpha channel & FSX -> DXT5

I would expect that this logic also works fine for a specular texture. The code that actually saves the texture has no idea what kind of texture it is now, I would prefer to keep it like that.

Does your specular texture have an alpha channel? Then I would not expect DXT1. Maybe there is a bug somewhere...
 
Yeah my TGA was 32bit with alpha and it seemed to create problems when it converted, let me test again when I get onto my next building (which should have a lot fewer windows :) )

I'll try and verify if it was user error or a possible bug, I was super tired yesterday.
 
Hi,

The logic will also check the alpha value. So if your whole alpha is white, you still get dxt1.

If you still think it is a bug, can you send me the texture?
