Now that the FTP is working OK for you....
Take a look at the test script. In the Pos element, you can specify the W and H attributes to use in text elements, which SHOULD specify the size of the text element and eleminate any weird sizing issues. I didn't actually change anything recently - it's been "fixed" for a while, just needed the correct skin definition.
I may work on some predefined "ZPoint" constructs, such as a sphere... so skinners do not have to calculate out the texture mappings by hand. Probably the sphere would be defined by flatness (disc, as opposed to a hemisphere, for example, warps the image much less). Basically, some simple primitives for use.
The idea is to replicate what Ava and Unleash(ed) do with 3-D objects to some extent, so skins can be transferred to MXM easily enough.
