shotgun spread is only vertical when aiming up or down, no hor spread.
this is for every shotgun.
EDIT: every weapon has it.

When explosion particle effects are created by GSR's weapons/equipment, an unusual particle effect appears at a specific part of the map (presumably the origin) with missing textures in place of sprites. The artifacting becomes more intense if multiple explosions occur and/or if viewed from different angles, creating giant glitchy "planes" of missing textures that stretch across the map. This issue occurs with:
-Frag grenades
-Claymores
-Landmines
-M203 Grenades
-Breach Charges

Notably, this does not seem to be an issue with all particles added by GSR; other things (smoke grenades, flashbangs, c4, etc.) with their own particles do not have this problem.

Edit: Forgot to actually include a video demonstrating the artifacting as I'd originally intended to do, oops.

When loading any map other than the first one (shoot_bang1) included in this pack the screen stays black. I've narrowed it down to just this addon that is causing this issue.

How to reproduce this issue:

1. Subscribe and enable to the Shoot Bang Campaign Map Pack (https://steamcommunity.com/sharedfiles/filedetails/?id=2722052799)
2. Subscribe and enable to the latest version of ARC9 Weapon Base, and ARC9-GSR.
3. Load map shootbang_2
4. Map will now display a black screen, intro text will still display above map.

ARC9:GetPhrase() is in arc9/shared which is loaded after the attachments in arc9/common.

Hello, I'm having a small problem when using the "C4 Explosive". Everything else is fine, however when I try to detonate the C4, I get this message, any feedback/fixing would be appreciated, thank you and keep up the good work! :))

This error occurs when attempting to switch to the M203 sights in ADS. This doesn't occur with no extra sights attached. (This might be a base issue.)

The third person weapon does not hang up when the round is finished, but you can see the weapon hang up in the first person, only when the round is finished ,press reload then you can see the third person weapon hang up few sconds

While in the meele animation, putting the gun on safe causes a glitch.

Hollow point ammunition seems to do an infinite amount of damage. I have uninstalled every other addon I have to ensure it isn't some weird damage multiplier thing from another addon, yet the issue seems to persist. You can one-shot Hunters, Hunter-Choppers, and Striders with it. I have also been instakilled by NPCs using hollow points.

That's what I get

The 15-Round .338 AWM magazine for the AWP states that the reload speed is slower when attached, but appears and functions as a straight upgrade. The reload speed is the same as the standard 10-round magazine.

I currently only have a 1070, and so I disabled clientside muzzle smoke effects via Arc9's settings. Unfortunately smoke effects still occur, regardless of settings, and tend to drop a lot of frames when shooting.

Does this work with the steam workshop version of arc9?

(Attention to the tracer)
In thirdperson bullet comes out in one angle, but weapon looking into another, making it kinda goofy

These are issues I discovered while playing around with the guns, some of them may be already known, others may not be

• In the Trivia section for the SCAR-17, it says it's chambered for 5.56x45mm NATO when the base model is actually chambered for 7.62x51mm
• When the carry handle is equipped on the M4A1-S without the M16 barrel length, the front sight is too far forward
• The M4A4 drum magazine's actual in-game capacity is 45 rounds instead of 50 (it is fine for the M4A1-S)
• When equipping a muzzle break on the M4A4, it looks a bit odd because the default flash hider doesn't go away
• The M4A4 has a strange side rail model when a tactical attachment is attached
• When there's an optic installed on any gun and the M203 with its sights is installed, the aiming for the M203 breaks completely and doesn't use the sights
• When the SCAR-20 doesn't have a scope or optic attached (so when using iron sights) the crosshair appears while aiming with it
• The Dual MP9s and Dual Sawed Offs don't have functioning camos
• Dual Sawed Offs have a blank HUD icon
• The Dual Sawed Offs don't display stickers (and possibly other personalisation options) in third person
• The MP9's 20 round magazine has a 21 round capacity (22 with +1 in the chamber)
• The UMP45's 12 round magazine has a 15 round capacity when equipped
• G3SG1 60 round NATO casket magazine has a 30 round capacity

I'll be posting screenshots of some of the issues in the replies below if need be in the future, thanks for making this incredible pack

P.S.: if I want to suggest things, where would I put suggestions?

It just makes three shots in thirdperson, but then you can hear shots only in first person, is it intended? Idk

Akimbo R8 in R6 conversion has 8 bullets in cylinder :(

I know gun pedantry like this is the most obnoxious shit ever, but still; the MAC-10 holds an extra round if reloaded while not completely empty, but due to realistically being an open bolt weapon it can't do that. (Funnily enough, the inspect animation for it even shows this- you can peek inside the action.)

Additionally, the trivia section lists its caliber as 5.56 NATO, but I'm assuming that'll be touched up with the recent wave of commits relating to weapon trivia.

I mean he holds it kinda badass but I think it isn't supposed to be that way

Exactly what it says on the title, equipping the attachment results in it being detached a frame later regardless of weapon or other attachments on the weapon. Only tested this on the latest commit version, so no clue if the Workshop version is also affected.

Most likely caused by the following error:

[[ARC9] Gunsmith Reloaded] lua/arc9/common/attachments/csgo_rail_optic_1.lua:20: attempt to call method 'GetPhrase' (a nil value)

This error is present for every att that support subatts.
Using the WS build of everything.

The AUG's default optic is the SCAR-20 scope. Right clicking an optic to remove it does nothing.

Taller than average or shoter playermodels cause this stretching visual bug, I just hope there'll be some pm height adjustment for anims. Also there's some thumb bone problem with this pm only, but other swep mods work at their finest, mostly not the arc9 addon issue but anyway

burst fire sometimes acts as automatic fire.

yeah, can turn the SCAR20 fully automatic.

The MP7 either doesn't show the debuff in it's debuff section, or it simply doesn't exist. I'm assuming this wasn't on purpose.

Like that one

You didn't find this
silencer

sometimes when clicking random preset the suppressor gets bugged and appears away from the gun, it looks like changing anything in the preset fixes it but putting the same change back breaks it again. couldn't replicate it by not using the preset though
