• 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.

Batch process for dxtbmp/imagetool

Hi everyone,

I want to convert a very large number of bmp-files to dxt3 with an individual alpha-map for each and no mips. Is there a way to automatize this using either imagetool or dxtbmp? I guess I will have to write some sort of batch process. Can anyone please let me know how to do this.

Thanks in advance,

Matthias
 
I don't think that dxtbmp can be used in batch mode.

Imagetool can be used in batch mode. To see the options that it supports:
- Open a command prompt window
- drag ImageTool.exe and drop on the command window.
- type [Space]-?[Enter]

You probably want to use the options -nogui -nomip -dxt3 -o newname.bmp

But I don't think that ImageTool will merge the alpha channel in from a 2nd file. You'll have to find some way of creating a single .tga file that contains both your image and your alpha channel. If you can't find any simpler method then the netpbm tools can do this.
