By popular demand, the Ancient-Shivan War team proudly presents its high-poly Satyr! Pictures can be found
here, the ship itself (model, textures, table) is available
on FreeSpaceMods (category Small Combat Vessels, because it's nearly the size of a Cain!). The Satyr was originally designed by Bobboau; the high-poly model, unwrapping and conversion were done by yours truly, all textures by freespaceking.
BEFORE YOU ASK: yes, the cannon is supposed to look like that. Try it in-mission, you'll see that it works like it should. (If it's somehow misbehaving anyway, please let us know.) To adjust the firing arcs, you need to modify the model (rotate-up bound) as well as the table (rotate-down and left-right bound).
