Think I just figured it out while tinkering with a model viewer thingy. Apparently the V values in UVs need to be inverted, but only if they are positive. For whatever reason. I think I remember seeing something like that in the context of wld-based stuff, should have realized it sooner :|

Will try to get fixes up later today or tomorrow ... once I figure out what to do to cancel it out properly. Too tired to think right now ;p

edit: Might be something peculiar to DDS format, even just fixing that weirds up my PNG stuff. May just need to stop automatically flipping PNGs/whatever-non-DDSes on import. Hopefully.

Ahh good. I'm glad it's not just me exporting models with screwy uv's.

The 3ds max OBJ exporter allows me to modify the precision of the UV's which I assumed that was the likely culprit.

Bit confusing to think about, but it's looking like the issue I was describing should only matter when converting DDS images to another format... I guess... although even then I'm not sure what would be needed to correct it yet ;p

I'm not sure what exactly your UV issue is, but if your UV values are extremely precise, something may be getting lost in translation. EQG uses 32bit floats, while I think the values in some of the material you gave me to test used 64bit doubles. Some of the least significant digits would be truncated to fit. Might try exporting with lower precision. At the end of the day it might be tough to get a huge texture pixel perfect over a huge mesh, though -- the bigger the image, the more precise the UVs have to be.
