I am pretty sure that you could use imagemagick for making a script that does the same thing as that workaround. Inagemagick works well in Cygwin under Windows or in Linux/OS X.

That is what I thought too.

As far as cubemaps are concerned, the TXI uses the Alpha layer of the texture to determine what is shiny and what is not. Without an Alpha layer, the texture with a cubemap applied to it either by the TXI or Appearance.2da will apply it to the entire object.
As far as what the TXI functions are, I only know of very few. There is, however, a topic on this forum devoted to listing them all that may be of some assistance.


It would surprise me if the presence of the "cube map" TXI-attribute implies that the alpha is a "shininess" map. I am pretty sure that I have seen specific attributes for that and, until now, I didn't know what they did. I will examine this when I get back to my computer.

I would appreciate a link to that forum thread. I tried to search for it but it is difficult on the phone.

There's likely a few solutions to add TGA support to your tool.

That looks really interesting, perhaps I should make a fork of CSharpImageLibrary, adding TPC support, and then use that in the tpc tool. It even has DXT compression done. :)

Interesting. I thought that since normal maps are stored in separate files, reflection maps and such would also be stored in separate files. I will think about how to handle this. Most likely, I will make an option to extract the alpha channel as a separate gray scale image and then add the possibility to provide two PNGs to create a new TPC file.

 

For now, this work-around in Photoshop might work:

  1. Open the converted PNG
  2. Menu: Layer->Layer Mask->From Transparency
  3. Alt-LeftClick the mask
  4. Ctrl-a Ctrl-x to cut the mask out. This will make the mask completely white, meaning that you can see all that info that the alpha channel was hiding
  5. Menu: Layer->New->Layer
  6. Ctrl-v to paste the mask into the new layer
  7. Edit the image and alpha layers to your hearts content
  8. With the alpha layer selected, ctrl-a ctrl-c
  9. Alt-LeftClick the mask of the image layer
  10. Ctrl-v to paste in the edited alpha channel
  11. Hide the "alpha" layer
  12. Save as PNG
  13. Use the tpc tool to create a new TPC file based on the new PNG file

I am not 100% certain that this will be perfectly accurate, but I think that it should work even if it is a bit clunky. Also, the tpc tool still can't create DXT-compressed images.

 

@sELFiNDUCEDcOMA about the GUI

Yes, that is one of the main points of this exercise: The code is structured so that there are libraries that handle the file formats and separate console applications for the tools I provide. Anyone could use the same libraries in their own GUI application directly, or call the console applications when needed. Many options are available. :D

 

@Malkior

The TXI can say many things. Most, as I understand it, has nothing to do with the alpha channel. Is there a list somewhere that explains what the various TXI attributes do? I have guessed many, but it would be nice to build a comprehensive list in a public space.
