Ok, I got it. The file provided with it is a an8 script file. You need to go to the "Scripts" tab on anim8or, "Run script...", select the file and... I don't know about the rest. I hope this helped, if it didn't, no surprise, I'm hopeless with anim8or.
Yes, get AC3D. It will make your life much easier when making addons for Orbiter.
1) The mesh has no textures even though they were textured. If i convert the textures to .dds how do i specify them?
2) The mesh is oversized (Thorton's ISS next to it for comparison).
The exporter converts 1:1m - what is one unit of dimension in anim8or large, is one meter large in Orbiter.
Send it to me, and I could resize it for yoou with AC3D in 2 min.
You said it was a mesh.
You need to convert the textures yourself into DDS format and put them into the orbiter folder, the anim8or converter can't do that for you.
It is also possible you need to check in the converted msh file (by a text editor), if the texture is named properly.
