[CSGO] Block flashbangs WHILE being 100% penetrable?

    Here's the situation. I have this hedge (below). I need it to tick the following boxes:

    1. Block flashbangs
    2. Be 100% penetrable
    3. Block LoS for bots and player names
    4. Bounce nades

    I can't seem to make 1 and 2 work together. If I give the prop a thin collision mesh with grass as surfaceprop, it's going to soak a whole bunch of damage, more than the player would probably expect. It does all the rest though. A nodraw func_detail on the other hand will do everything except block flashbangs. Please tell me there's a simple solution to this that I've missed? I've gone through all the tooltextures to no avail. Worst case scenario is that I go with collision mesh.

    I made a test map to try out some things myself (many you probably tried too). The closest I got to what you need is a 1 unit func_detail covered with nodraw (combined with a grenade clip brush to bounce of nades). It does everything, except it's around 50% penetrable.

    I'm guessing that the ability of an entity/tool texture/whatever to block flashbangs is directly linked to its solidity.

    This sure seems to be the most viable solution. I found these numbers (roughly) in terms of penetration, within falloff distance for a 1 unit nodraw:

    P2000 - 47% loss M4A4 - 25% loss Deagle - 25% loss AWP - 20% loss

    Meanwhile, grass or dirt stops 68% of the P2000 damage. Thanks, case closed! :)

    Maybe you could try to make the noclip wall even thinner than 1 unit.

    For that, select your brush, press CTRL + M, change the Scale and put 0.25 in the appropriate direction (the direction of the thickness) and 1 to the two other axes. Your wall should then be 0.25 unit thick, and since bullet penetration is calculated with continuous mathematical functions, it should reduce the loss.

    You're right. I gave that a shot as well, but forgot to mention it. Is 0.25 the thinnest you can do without crashing the compiler?

    But it doesn't block bullets.

    Probably not but i know it works and it should reduce drasticaly the loss already :P

    Did it work ?

    I tried a 0.1 think brush and its impact on penetration is marginally or even non-existant. In fact, it doesn't even show an impact (sv_showimpacts 1). Only tried with a USP-S though.

    It still blocks a flashbang just fine, so seems like we found a solution :) *highfives @leplubodeslapin*

    grenade_clip brush

    +

    clip or player_clip

    does this not work? (Why?)

    Clips won't block the blind effect of flashbangs. For regular clip this is reasonable, considering they are everywhere. Grenadeclip however is so niché that I'd say it would be reasonable for it to block flashes. But it just doesn't.

    Oh ok, so the problem is that the tool texture is "bugged"… good to find a workaround but Valve should fix it then.

    hopefully they'll read what clan killer posted.

    Is it not possible to configure the collision mesh to let bullets through without absorbing power?

    Its purpose is to bounce grenades physics, unlike clip that only blocks players and the bomb, so it's working as intended. Though I'd consider it reasonable if it blocked flashbangs as well considering how niché it is. There might be a scenario where this would be bad but I can't think of any.

    Sorry I'm getting confused, is it blocking a flash bang grenade, bouncing it back, or not? @grapen Are you complaining that the flash gets through (explosion)

    cos in the second case, like Squad, I wouldn't think it's bugged. But I'd expect the nade to bounce back.

    Bottom line though, seems to me there should be more control over the collision mesh, we should have checkboxes to tick like "bullets pass through" "grenade pass through", a custom value to input how much power from bullets is absorbed etc.

    Grenade Clip does exactly what it says it does (unlike Block Bullets :p): it bounces grenades, but doesn't blok flashbangs.

    A chain link fence. Can you think of a scenario where it should block flashbangs and there is no alternative way to set it up?
