Compression artifacts occur when trying to use DXT compression

[djsigmann]

There seems to be some artifacting when creating VTFs with DXT compression when compared to vtex2.

MareTF v0.12.0 - maretf create -v 7.4 -f DXT5

vtex2 v0.3.1 - vtex2 convert --version 7.4 -f dxt5

I can observe similar artifacting when creating VTFs with DXT3 or DXT1.

I'd upload the VTF files themselves, but I'm not sure I'd be allowed to here on github, since they are compiled from valve's textures. Please let me know if I can and should upload them.

Do you observe the same artifacts with -q 1.0? It's meant to default to that for DXT1-5

I do.
I did in fact, re-run the command with -q 1.0 to be sure (maretf create -v 7.4 -f DXT5 -q 1.0 sign067.tga), but as I understand it, 1.0 is the default for DXT1-5.
-q, --quality...If quality is below 0.0, default compression values will be used (0.1 for BC7, BC6H, and 1.0 for all others)...[default: -1]

This should be fixed now

@craftablescience I can still observe this behaviour after recompiling the latest tag (MareTF version v0.12.1).
