Sure thing! The first thing you need to know is that custom textures can bypass sv_pure by being placed in the vgui/replay/thumbnails folder. This isn't limited to just custom CP icons; it applies to any other texture you want to use in the HUD.

After I created the icons and named them appropriately, I converted them to VTFs and put them in the folder above. Following that, I extracted the corresponding VMTs and placed them in their proper directory (sprites/obj_icons in this instance), and changed the $basetexture parameter to reflect the icons' new location in vgui/replay/thumbnails.

This is where most custom textures can stop and be expected to work. But the CP icons are special for some reason. Maybe because they're dynamic and can be called in and out during a typical CP round? Who knows, but Wiet and I figured the icons needed to be preloaded since they only showed up if you joined a listen server prior to joining one with sv_pure.

I did the preloading by referencing them on the main menu. You will need to append some code somewhere in mainmenuoverride.res to set this up. Here's what mine looked like for icon_obj_blu:

	"cpicondummy1"
	{
		"ControlName"	"EditablePanel"
		"fieldname"		"cpicondummy1"
		"xpos"			"9999"
		"ypos"			"9999"
		"zpos"			"11"
		"wide"			"0"
		"tall"			"0"
		"visible"		"0"

		"SubButton"
		{
			"ControlName"	"CExImageButton"
			"fieldName"		"SubButton"
			"xpos"			"0"
			"ypos"			"0"
			"wide"			"0"
			"tall"			"0"
			"autoResize"	"0"
			"pinCorner"		"3"
			"visible"		"0"
			"enabled"		"0"
			"tabPosition"	"0"
			"textinsetx"	"0"
			"use_proportional_insets" "1"
			"font"			"VersionFont"
			"textAlignment"	"west"
			"dulltext"		"0"
			"brighttext"	"0"
			"default"		"1"

			"SubImage"
			{
				"ControlName"	"ImagePanel"
				"fieldName"		"SubImage"
				"xpos"			"9999"
				"ypos"			"9999"
				"zpos"			"1"
				"wide"			"12"
				"tall"			"12"
				"visible"		"1"
				"enabled"		"1"
				"image"			"../sprites/obj_icons/icon_obj_blu"
				"scaleImage"	"1"
			}	
		}		
	}

All I did was create an element with a sub-image that I could use to reference (thereby preloading) the icons. Then I made damn sure to keep it hidden by setting the x/ypos way off-screen, hiding everything etc.

Forgive me for my late response; I'm used to being the only one who posts here nowadays, so I don't check back too often.

Fixed.

Neither of those files exist.

v4.50

Got tired of the default CP icons and they weren't visually cohesive with the HUD anymore, so I redesigned them.

Big ups to my friend Wiet for helping me figure out how to make the icons bypass sv_pure and make them visible on any server. E-donuts on me fam :B1:

- designed new cp icons
- revised round counter display in matchmaking/casual
- red/blu team color tweaks
- removed heavy/pyro war button
- fixed demo sticky positioning in centered version

Yeah, the cursor shows up, but nothing happens when you click on players.

I'm very late to this, but no one mentioned it to me until now. Apparently my HUD does not work with tf_scoreboard_mouse_mode. Is there something I need to add to make the popup show up? Nothing happens when you click on a player in my scoreboard with that command set to 1 or 2.

v4.49

Just compatibility fixes for tonight's update that added map selection to the casual lobby.

- updated for july 14 patch

That's developer 1. Set it to 0.

That's a common issue with custom HUDs. I do not believe there is a fix.

Demos do not store the fact that it recorded a matchmaking game. It will play back with the non-matchmaking HUD. I believe Wiet has contacted Valve to see if they'll add back a cvar to allow us to force it while watching demos.

Yes, I know about the quickswitch fix but that seems unnecessary. There should be a way to remove it without a workaround like that. I guess I'll check out the hudlayout diff, but I'm pretty confident I updated everything that changed in my HUD.

After the meat your match update came out, I started hearing reports of this black loadout box appearing at the top of the screen. It doesn't allow people to switch weapons while it's active. Anyone know what this is?

Wow dude. Look literally 1 inch above your post. New levels of ignorance.

Has that always been like that? Never seen it.
