According to this post:

the beam splitter is not fixed as of the Dec 13th patch.
That's a shame.
Antistar, I think the Big Boomer and regular Sawed off Shotgun look too similar in those pictures.
Maybe if you made all the wood and metal darker or something on the Big Boomer to show the difference.
That's exactly what I did, actually. The diffuse map for the fully modified Big Boomer is noticeably darker than that of the fully modified Sawed-off Shotgun; however the spec map is not (so it looks quite a bit brighter due to the lighting in that shot). The reason for this - and the reason the Big Boomer's diffuse map is not darker than it already is - is that if it's too dark, the details of the texture won't be visible; particularly with the variable lighting in the game. This is a problem seen with a lot of the quick and dirty "I made it black" retextures seen on the Nexus, for example; it's just a black mess - you can't see anything.
That's for the metal. For the wood, well it
is maple - a relatively light-coloured wood - and also if it's made too dark, there won't be enough contrast with the branded 'Big Boomer' text on the side.
Trust me; I did weigh all these things up.

Having said that, there's always the possibility for tweaking things... but I don't know if it's strictly necessary here. In this thread you can look at those two pictures side by side and compare them, but it would be very unusual to be looking at a fully-modified Sawed-off Shotgun right next to a fully-modified Big Boomer in-game.
@Antistar
Everything is looking terrific so far, I look forward to a release of WMX. Keep up the good work.
Questions:-
Will WMX be compatible with Arenovalis' lovely weapon reskins? What would be the appropriate install order - WMX first with Arenovalis' skins overwriting or the other way around?
Thanks in advance.
WMX doesn't overwrite/replace any files, so install order won't matter. However, a number of modified weapon variants use altered textures based on vanilla textures. If Arenovalis continues releasing retextures at his (remarkable) pace, it may come to be that a number of the modified variants will not match the texture of their unmodified version (if someone is using replacer textures).
It's worth noting that WMX forces the Caravan Shotgun to use vanilla Obsidian textures; except for the 'Improved Parts' variants, which use modified versions of Arenovalis' textures. The vanilla textures could still be replaced by Arenovalis' textures though, if the user really wanted.
Anyway. I can envision an optional WMX 'retexture pack' possibly being something a lot of people will want in the future. It could include the relevant WMX textures remade using Arenovalis' textures as a base; as long as he is fine with that, of course. That's just speculation right now though, at any rate.
Edit:
Idea:
For the recharger weapons, change the recycler mod effect from "regen ammo (shots)" to "regen ammo (seconds)" and put in a negative number for the value (for example a value of -0.25 for a reduction in recharge time per shot of a quarter of a second). That should speed up regen evenly which would make more sense for a self-recharging weapon. Maybe give it its own mod and call it "Fast Breeder Controller" or something similar.
Anyway, just a thought ^_^
Something like that did occur to me when I was working on it, but I haven't tried it. We'll see.
