imagedds _a wrong conversion

[demostenes]

I ve noticed, that if I convert texture with _a, it is not converted to R channel texture, but it creates dxt5 RGB texture with all channels black (does not matter, if input has 1 channel or 3). I would expect, that it will create only R channel texture. I am using latest imagedds.

Hi Jirka,

 

Any steps for reproduction? Did you use python script or just some bat file and imagedds.exe tool? 

 

As a workaround you can always do the:

imagedds.exe -f ati1 texture_name_a.tga

Thanks!

Hi Jirka,

 

Unfortunately, I can't reproduce this issue with attached textures.

 

My steps are:

1. Create folder textures/uncompressed;
2. Copy *.tga textures inside uncompressed directory;
3. Copy imagedds.exe + imagedds.py to uncompressed directory;
4. Run imagedds.py via double-click;
5. Check textures directory: there are two dds textures with ATI1 compression near the uncompressed dir.

Thanks!

I see cause of the problem now. I had obsolete python file. Now unigine see created .dds file as R channel ATI1 (correct). Btw, when I open it in Photoshop via nvidia dds plugin, it sees it as RGB file with all black channels. It seems, that it is not able to read it properly, even without saying any error.

 

So consider this solved, thanks for assistance.
