If you've got a log file from a game where both mods were enabled, pastebin it for me. I spent a lot of time making sure that any item that went into the secondary slot, regardless of mod/weapon type/time of release, would be copied into the utility slot, and I'm unsure why shields wouldn't be copied.

Due to how the shields function, with regard to added animations, putting them in the utility slot will probably break something, but meh?

I really wish steam would auto-subscribe me to discussions on my mods. It's a toss-up whether I even know a new discussion exists.

Oh. Wait. I am very dumb. You would need to add "+GenericCategories=shield" to the ini. That would make the mod generate copies of the shields.

Waiting for an update ;)

In my part. I tried to edit some changes in your ini file which is the XcomUtilitySlotSidearms.ini... I added this lines

+MeleeCategories=shield and shield shown up at the utility slot but it breaks the animation.

Yeah I figured. The animations rely on the shield being in the secondary slot. That’s something the shield mod would have to fix to be more universal.

How can I add the biotic amp to equip in the utility slot
