: The most stable (least likely to be changed any time soon) texture set is
: probably set 4, so if you'd like to convert that, I'll be happy to check
: it out. I don't think any one set is any more or less likely to look bad
: under high compression than another set would be.
OK, http://www.treellama.org/EternalDDSTest.zip
Replace set 4, put the landscape in your landscapes, and add the MML file to your scripts folder. The DDS files are all compressed (but not with Aorta), even the landscape, and I'm hard pressed to tell them apart from the pngs. Let me know if your load time improves, and how they look. If you have an geforce card, you may have to play with the geforce fix in advanced prefs.
I've added type="" attributes to the MML, so your texture quality settings (normal, high, higher, etc.) will apply.
