Try which the 2/24 Build...That works fine for me... if that dont work go on for Goobler 2/20.
This Pack already have the Low-End Shockwaves, its in freespace2/data directory (in /Models and /map as say in the Shockwave thread and readme) it should be in mediavps/data, but, is working anyway... Remember to use OpenGL not D3D...
lol damn, I forgot something, The HTL URSA its not really installed... When I install the HTL Apollo, HTL URSA and Hi res Lucifer in that moment I think that SCP is looking for files in any folder inside the /datas, but is not... (that is a big mistake if you ask to me), for That in a first time I Put the Apollo in "Freespace2/fs_port/Data/HTL_Apollo", the Ursa in "Freespace2/Data/HTL_Ursa" and the Hi res lucifer in "Freespace2/Data/Hi_res_Lucifer", That in a first moment, when I discover that is not working (its should be, that could be great for a little organisation, because if you have many modifications you going to having a lot of files and is hard to see for what is everyone), anyway, in that Moment I re-edited and the pack and put the HTL_Apollo files in the fs_port/data, check it and repack it, and say to re-download the torrent is someone is already started to download them (Page 1 of this post), but I complety forgot the Ursa and Lucifer lol

(well The Hi res lucifer can causes slowdown because of its poly count), but the Ursa files should be go in mediavps/data or freespace2/data or not going to work.. anyway, is not so important.
