render beam not rendering properly?

[safforiveunch]

for whatever reason, i can't get this to render a beam properly.

it should render a beam in front of the local player's eyes instead it doesn't do anything at all even though it doesn't crash or return any errors.

any help would be greatly appreciated:

oh wow, can't even use a codebox.

HUDPaint isn't a proper rendering block. You either need to start a 3d camera or move to a different hook.

Along with what Kogitsune said, use one of the render hooks that Wizard posted and also try to avoid creating the beam directly from the EyePos, from a direct angle you wont see much of the beam because it's a 2D material getting laid out in 3D space, so it might just appear as a thin line from your perspective.

Use LocalPlayer():GetViewModel():GetAttachment(LocalPlayer():GetViewModel():LookupAttachment("1")) instead of EyePos.

Draw in cam.Start3D2D.

What the hell are you talking about?

Also you better cache the id.

my actual goal isn't to draw a viewmodel of the lasers, but just a view of what the player is looking at that points a laser (in future material) at it. i plan on changing it from local but yeah i tried out most of that stuff and it didn't work

edit: nevermind, it actually does work but its behaving strangely

it's actually drawing from a point in the map i think and not from the player's perspective, i changed EyePos to EyeAngles and added the 3d cam but still no good

Drawing a 2d beam in 3d space doesn't happen in a 2d drawing function.

Post the code.

He is drawing a beam in a 3d realm, do you even know what cam.Start3D2D does?
