Can someone explain how call companions work? Do the companions come to the pc in game time or is it supposed to work like a summon spell so they appear within seconds of using call companion?
Yes, the "Call Companion" lesser power works like a summon spell. It only works when an NPC is following you. If they are waiting or have been dismissed, logically they can't be called to you.
Anyone have a link to a tutorial for creating your own custom NPC to use as your companion
?
Well, I don't have a link, but I learned to make mine via a text file/ document that comes with the CM Partners Base mod. That mod comes with a "readme" type file that tells you how to make CM Partners NPCs. I taught myself how to make an NPC through that file.
When the mod is active, it seems to replace the default greeting for every NPC in the game, at least that I can tell. Maybe its just the vanilla characters. Anyway, this is a problem for me as frequently NPC’s will have custom spoken dialogue greetings, and frequently that dialogue will be specific to the stage of a particular quest you might be on, etc. The mages guild people come to mind.
The problem is that ALL of this gets replaced by the generic companion share greetings, which being custom text are silent. I would like to suggest a version that keeps all the same functionality, the same menus, the same dialogue options, but does away with the custom greetings.
I usually work around that by simply dismissing the companion until the needed dialogue exchange is completed. Then just recruit them again.
So far this the most noticeable problem I found in CSR: when you sneak and attack enemies your companion sneak and attack too, but he continue sneaking and fighting even if you are no more in sneak mod during the fight. Quite annoying sometimes.
So when a fight starts after you've been sneaking, you stand back up but your companion remains in the sneaking stance (crouching)? The only instance of this happening to me is when the companion is too far away or the PC is in water. AFAIK, TalkieToaster implemented some companion commands to execute via targeted spells and targeted spells don't work while you're underwater. For some reason these companion commands don't work even when you're only ankle deep in water.
Yet vanilla targeted spells do.
I can only hope Talkie isn't too busy with his other modding endeavors to polish up this one some more.
