I tried to add a shortened blue lightsaber to a Gungan and got the resulting severity 3's:
Is the luke animation missing? I thought that was loaded by default....

Wait, do you, by any chance, have a more than one primary weapon and then have any secondary weapons? Because if you have a melee weapon, you can only have (at maximum) one primary and four secondaries, or 5 primaries and no secondaries.

The unit's odf:
I don't know how to add more weapons to a unit, so there's only 1 primary and 1 secondary.

you have to put the "all_hero_luke_jedi" combo file into your odf-folder

Thanks, issue solved. But what if I wanted to make it slash, not like Luke, but like the Emperor? I suppose I would have to copy over the Emperor's COMBO, but what do I change in the saber's odf?

you cant just give combos to different anims, they will break most of the attacks (thats because the combos load all the anims, and not every unit has an own jumpattackanim or 1c_end anim)

to understand how to mix anims, read the jedicreationdoc, the scaling up units tutorial (for information how to munge new animsets, in the everything...thread) and the comboguide or however it was called by metalcorerancor (for informaion how to edit combos, in the released assets thread)

Well, I won't bother with it then. Anims confuse me, and I don't want to wreck my map. I suppose one day I'll make a test map and try this out, but for now it's not crucial to give the unit Emperor anims. It just looks somewhat wierd to hold a .2-meter blade with both hands. Is there a way to take block out of the COMBO easily?

yes, it is look on this or the last forumpage, there will be a topic about removing block
