looks like he's using a low viewmodel_fov + r_drawviewmodel 0 to make his beam smaller. Try to use viewmodel_fov 50 + r_drawviewmodel 0 to see if it works.

Doesn't viewmodel_fov 0 just remove all added particles and tracers, jsut try both I guess.

No, you need to put both at the same time. If you only put viewmodel_fov 50, the beam will get smaller, yes, but the weapons will be super big on your screen and it will take a lot of screen space, expecially when you reload your primary weapon. You need to put r_drawviewmodel 0 as well so it hides your weapons completely.

Thanks, but I'm mostly referring to the brightness of it, like how on his screen the medibeam is very transparent and pale:

while on my screen, the beam tends to stack and look bright white fairly often:

dx9 gives a closer look to the beam in the video, but it doesn't look like he's using dx9 really. I'm wondering if the same transparent effect is possible while running dx8.

viewmodel_fov 0 also completely hides your weapon...
AND it also removes tracers from hitscan weapons.

this may or may not be what he is using, but here:

pop that into your custom folder and it should make your medi beam less dense

it does not work in pure severs, just like every other model, material, and particle mods.
and thanks for using medHUD!

thats exactly what it is, thanks. unfortunately it doesn't work in esea servers :/

thanks though!

pretty sure hes using chris max/highframes config + viewmodel_fov 0 + r_drawviewmodel 0. I don't use any materials pack and mine looks pretty much like that.

r_drawviewmodel 0
viewmodel_fov 1

^hides beam completely, you will see small puff/cloud coming out from patient's buddy

Try it

Since that VOD is 2 years old, i assume it was an old Medigun beam bug, where it went transparent after healing for few seconds, was only for Dx8 i think

Put viewmodel_fov 25 into your med cfg to push that shit out of the way (including that annoying blob)
Being able to see the beam is still somewhat helpful

Oh, this is how the beam used to look. Not sure when but, there was an update in which Valve made the dxlevel 81 Medigun beam really bright along with teleporters.

How to get that back?

From what I know, without using a custom thing, there's not an exact way to make your beam look like that again, BUT, as others have posted, by changing your viewmodel_fov around and turning off viewmodels and all, you can have a beam that looks smaller and duller than how it currently is.
