FWE doesn't add as many weapons as FOOK2 does so I figured that RH Ironsights would work alright with it. Has anyone had any issues running them together?

I've been wanting to DL RH Ironsights for a while but I too run FWE and didn't want to run the risk of having an issue either. So, I'd also like to know.

Use FO3edit to check. There is a really good tutorial on it somewhere in these forums. If I had to guess I would so they are not compatible, but I am not at all familiar with the mod.

Looks like it changes animations to do what it does, so it won't work. Maybe using FO3edit merge or BASH would do the trick. Does BASH work with weapon entries?

RH Ironsights is not compatible with FOOK or FWE.
Alone for this reason: Ironsights uses specially adjusted models so the gunbarrels dont get in the way. There are no such models for FWE, FOOK or almost any other custom weapons, so the usual result will be the gun taking up most of your sight and you wont be able to see whats infront of you.

But this only happens with new models that aren't configured to use ironsights, correct? Because I noticed it using RH IS with custom weapons before.

This really needs to happen. I've started a new game using Arwen's tweaks and using RH_Ironsights is AWESOME - cos Arwen doesn't use any new weapons, it's fully compatible, with a little easily made patch in F03Edit to add some weapon effects to the new guns added by RH_Ironsights. If the new FWE models were added it'd be great. Rogue Hallow is in the process of adding CFW models included in EVE, so it'll happen eventually.

And a FOOK2/RH Ironsights CP is in the mix too.

RH_Ironsights is mostly compatible with v.4.3 of my Realism Tweaks, but with a few minor animation conflicts, loss of my weapon effects on a few weapons, and some minor damage / spread balance issues.
Version 4.4 of my mod should be 100% compatible with RH_Ironsights.

Im using RH Ironsights with FWE, however alot but not all of the new wepons have issues with taking up the entire screen but I dont realy like most of them so its not a big deal to me. So far (I have not done extensive testing) all new pistols and small gun rifels that FWE adds have worked (you have to do some small tweaks in FO3Edit or G.E.C.K.) but energy wepons and big guns, LMGs and such have not. Also if you have WMK and like scopes just pop one on your gun that is having issues and it will work fine. Basicly it has a lot of issues and a few things that work wich in my opinion is worth accepting to be able to use RH Ironsights.

Does anyone know if RH Ironsights is compatible with EVE...?

Not really. You can use the two together, but their are some major conflicts in some of the energy weapons . . . which means that you end up loosing some of EVE's changes if it loads before RH Ironsights; or you loose some of RH Ironsights' changes if it loads first. These issues can be corrected by editing the mods in FO3Edit, but what is really needed is a compatibility patch.

Thanks Arwen.
