if you're talking about the tiny marker at the bottom right corner, you'll have to edit the image using VTFedit. they're found in the custom\...\materials\vgui\replay\thumbnails\ folder, under the names bg_bluetri and bg_redtri. open with VTFedit, right click, copy, put into your favorite image editor. when done, click file>import and find your edited image, copy the flags from the original file, save as, then replace the original file in your custom folder and you should be done. (haven't tested so I might be wrong)

if you're just trying to enable captions you already have, 'closecaption 1' in console enables them. if you don't already have captions installed, theres a tutorial here for making your own. otherwise you could take someone else's closecaption_english.dat/closecaption_english.txt and put them into your custom\...\resource folder

scoreboard:
open custom\..\resource\ui\scoreboard.res, ctrl+F MainBG
look for fillcolor and change it to 'TransparentBlack' or 'TransparentLightBlack' (or something else if you don't like those)

killfeed:
open custom\..\scripts\hudlayout.res, ctrl+F HudDeathNotice
change basebackgroundcolor to 'TransparentBlack' (or another dark color) and localbackgroundcolor to something like 'OrangeDim' (pre-defined color. it's a pretty transparent white)

for those wondering about the control point thing sandrider has in his screenie,

open up your hud's scripts\hudlayout.res and ctrl+F HudControlPointIcons
the part you're looking for here is "seperator_width" and "seperator_height"
lowering these values brings the control points closer together, cutting off borders on the sides (_width) and on top and bottom (_height)

example 32x32 control point icons (res\ui\ControlPointIcon.res), 1680x1050 resolution, "seperator_width" "-5", and "seperator_height" "-5"

beware this makes A/D control points look horrid (koth seems ok), and the capping overlay (the arrow that goes through the point as you cap) might be not sized correctly

last i played tera (2-ish months ago) my fps problems were because the game was pretty badly optimized. like if you turn off the ingame hud with the screenshot mode shit, you'll get big fps jumps. couldn't figure out any other way to get higher fps other than upgrading hardware

go into your resource folder and rename/delete SourceScheme.res
should fix the white menu thing.

not sure about your graphics tho. might have to do with steamcloud?

one thing I think you could do is have two copies of the same crosshair in your hudlayout.res file, one translucent and one opaque, and when you dont want one of the crosshairs up, set its x/ypos to something really high so it doesn't appear

e.g.

	"xhairOpaque"
	{
		"controlName" "CExLabel"
		"fieldName" "xhairOpaque"
		"font" "xhairFont"
		"fgcolor" "0 175 255 255"
		"labelText" "f"
		"xpos" "c-100"
		"ypos" "c-97"
		"xpos_minmode" "2394723"
		"ypos_minmode" "3479654"
		"wide" "200"
		"tall" "200"
		"visible" "1"
		"enabled" "1"
		"textAlignment" "center"
	}
	"xhairTranslucent"
	{
		"controlName" "CExLabel"
		"fieldName" "xhairTranslucent"
		"font" "xhairFont"
		"fgcolor" "0 175 255 155"
		"labelText" "f"
		"xpos" "438623432"
		"ypos" "23794623"
		"xpos_minmode" "c-100"
		"ypos_minmode" "c-97"
		"wide" "200"
		"tall" "200"
		"visible" "1"
		"enabled" "1"
		"textAlignment" "center"
	}

edit: should probably verify first, hud crosshair or ingame crosshair?
if hud crosshair, above should work. if ingame, you can just stuff cl_crosshairalpha "x" in every class config in your cfg folder

i dunno. you could try, but i'm also on a 16:10 aspect ratio resolution and _widescreen ones work fine for me. are your images resized correctly beforehand?

looking through the gcf files, it looks like the current halloween bg is named "title_team_halloween2012.vtf" (title_team_halloween2012_widescreen.vtf if you're on a widescreen res)

what resolution are you using?

I'm not sure if there's a less redundant way of doing it, but here's the way I do it.

1) pick your image
2) convert it to a vtf through VTFedit
3) go to your \team fortress 2\tf\materials\console\ folder. if it doesn't exist yet, make the folders
4) move the vtf you made here and make a few copies of it, renaming each one to:

background_2fort_widescreen.vtf
background_gravelpit_widescreen.vtf
background_mvm_widescreen.vtf
background_upward_widescreen.vtf

and you should be done. it feels pretty ugly doing it this way, but it should work just fine

scripts/hudlayout.res
"HudDeathNotice"

try changing the 'wide' value for CrosshairCircle in scripts/hudlayout.res to something bigger

edit: nvm. played around with it before i went to sleep. you're gonna want to go into resource/clientscheme.res, ctrl+F CircleFont, and change the 'tall' value from 24 to something larger, 30 seemed to work when i tried it

yup! just open up the hud_layout.res file in your scripts folder, find the crosshairplus/crosshaircircle sections, and just start changing the xpos/ypos values, saving the file, then using hud_reloadscheme in console.
i usually center by turning on the ingame crosshair, i think its crosshair7 or something, just a simple cross, and trying from there

if you just want to upload your resource/scripts folders and give your resolution, i could just do it though i guess lol

omp's already has all of this in by default actually, you just have to enable it

specifically:

at the bottom of hudlayout.res (just change the 'enabled' and 'visible' values to 1):

"OmpCrosshairPlus"
	{
		"controlName" "CExLabel"
		"fieldName" "OmpCrosshairPlus"
		"font" "SymbolSharp24"
		"fgcolor" "0 255 125 255"
		"labelText" "+"
		"xpos" "c-100"
		"ypos" "c-103"
		"wide" "200"
		"tall" "200"
		"visible" "1"
		"enabled" "1"
		"textAlignment" "center"
	}
	"OmpCrosshairCircle"
	{
		"controlName" "CExLabel"
		"fieldName" "OmpCrosshairCircle"
		"font" "Crosshairs24"
		"fgcolor" "255 255 255 255"
		"labelText" "9"
		"xpos" "c-100"
		"ypos" "c-98"
		"wide" "201"
		"tall" "200"
		"visible" "1"
		"enabled" "1"
		"textAlignment" "center"
	}

and in HudAnimations_tf.txt:

ctrl+F "event DamagedPlayer" and it should look something like this..

event DamagedPlayer
{
	//Animate	OmpCrosshairPlus		FgColor "255 0 0 255"		Accel 0.0 0.0
	//Animate	OmpCrosshairPlus		FgColor "255 0 255 255"		Accel 0.2 0.0

	//Animate	OmpCrosshairPlusSmall	FgColor "255 0 0 255"		Accel 0.0 0.0
	//Animate	OmpCrosshairPlusSmall	FgColor "255 0 255 255"		Accel 0.2 0.0

	//Animate	OmpCrosshairCircle		FgColor "255 0 0 255"		Accel 0.0 0.0
	//Animate	OmpCrosshairCircle		FgColor "255 255 255 255"	Accel 0.3 0.0
}

just take off the comment //'s in front of the OmpCrosshairCircle section, and change the coloring to your preference.

tl;dr: http://www.mediafire.com/?ju5vi9mk19y1ho1

in either of these, you're probably going to have to recenter everything on your own though (i play on 1680x1050), just something to keep in mind

http://www.mediafire.com/?omlml29m812my6k

here you go! i tried to center it as much as i could, so if it's noticeably off, lemme know and i'll see what i can do.
