if u have milkshape do this:
tools>half-life>decompile normal HL model
choose an MDL file (all models for all mods are in moddir/models)
ok .. go to the folder of that model. ou will see a whole load of smd files!! one of them got the mesh (the model itself) with the bones! the rest have the animations! every animation is put in a file! try to open them in milkshape. go:
file>import>halflife smd
if u want the the file that contains the model it self i think it
s name should be just the name of the model (i.e. for goku it's goku.smd)
ok .. you will see some "bones" these are the blue balls and lines (i am talking about milkshape here) when you animate you basicaly animate the bones and the model will animate with it!
this is just a basic thing ..
ok .. lets' say you made an animation now!! now go to:
file>export>half life smd
that wil export the animation!!
if you just want to replace a sequence then just recompile these smds (with the bmps and the qc file) and ur done!
to do that go:
tools>half-life>compile a qc file
choose the qc file in the directory of that model!
DON'T FORGET TO BACKUP THE ORIGINAL FILES!!!
if you are making another animation you need to edit the qc file and add it in there. but you prolly won't need that unless ur making your own mod!!!!!
hope that helps!
