• 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.

Texture Converting (24bit+alpha=dxt3 without mips)

Hi all,

I previously used "FS Texture Converter" to convert me 24bit image + 8bit alpha channel into DXT3 pics, but FS Texture Converter automaticaly adds mips. Is there any other software that can do the same and give me an option to leave the mips out?

Kindly,

Blazer
 
Have you tried ImageTool?

Hi Arno,

Sorry for not replying sooner. Was at work till late last night and today.

Will imagetool do this batch convert thing? Can you give me an example please or command line of how to make it select a folder our the input files, a folder for mask channel and and output folder or similar way?

Thanks for your help.

Kindly,

Blazer
 
Hi,

Yes, you can run it in batch mode from the command prompt. Just use a command like this:

imagetool -dxt3 *.bmp

This will process al BMP files found to DXT textures (default extension of ImageTool is MIP). If you just type in imagetool -h on the command prompt, you get a list of all possible options.

I don't think it can take a second file as masks though, I always put the the alpha channel already in my image before I make a DXT out of it.
 
Hi Arno,

Thanks again for your help. this is what I currently do:

Have my airport ground layout in a PSD photoshop file in layers. I save the ground as a BMP file then make only the layer which will be the alpha channel visible and save that as another BMP file.

Then I use BMPCrop to slice the big file into 512 or 1024 sizes BMP files in both the normal and alpha image.

Then I use FS Texture converter to convert the sliced groundimage + slices alpha channel into DXT3 files, but the problem is that it automaticaly ads mips. If I use with MIP in FS, I get the seams, even editing the mapping within gmax so that the last pixel isn't used, so my only solution would be to do it without mip and seeing how I change the ground all the time and my current work has over 30 images, you can see how time consuming it can be to manually open the BMP in DXTBMP, open the alpha channel then save as DXT3 without mip.

Just looking for a easy way to do it. If there is none, then I'll have to settle with what I have now.


I guess that I could get an already DXT3 image and reconvert to DXT3 with imagetool only without mip... gonna try that soon.

Thanks again.

Kindly,

Blazer

OBS: After the initial post I tried what I said above and it works. The commandline used was "imagetool -dxt3 -nomip *.bmp" Worked like a charm.
