No need to pester me with private messages
As I wrote, all you need to know should be in this thread:
viewtopic.php?f=82&t=4361What it boils down to (if I remember correctly) is that you need this exporter:
http://www.katsbits.com/files/md5/io_export_md5-263.zip and Blender version 2.63a
And this importer
http://www.katsbits.com/smforum/index.php?topic=358.0 with Blender version 2.61
NOTE: The mesh system between 2.61 and 2.63 changed so a .blend saved with 2.63 will not open in 2.61 correctly. It works the other way around though so if you want to import animations your safest bet is to work only in 2.61 and use 2.63 exclusively for exporting.
Another thing that took me a while to figure out is that you absolutely have to have a material and an animation applied to your mesh/rig, otherwise it will not export, even if all you want is an md5mesh and no md5anim at all.
If you want to mess with the hud_hand use the reverse engineered rig I posted in that thread linked above.
But quite honestly, that the weapons and hud_hands are still in md5 format is an old left over in RE, normally all of them should be done in .iqm like it is the case for the playermodel. If you have a look at how the playermodel is done, it shouldn't be to difficult to figure out the way the weapons need to be. And the .iqm exporter works like a charm with the newer Blender versions.
