Ok, finally. I had difficulties and I had to make dedicated server also.

Use sm_test to spawn button in front of you.

- prop_dynamic glows when player aim to func_button.
- Will glow through walls, but player need still aim to func_button
- Not sure, does other players see glow when another player aim func_button
- When press button, it stay in (-1) and glow stop when button in.

I guess, this not satisfy you...

PHP Code:

#include <sdktools>

public void OnPluginStart()
{
    RegConsoleCmd("sm_test", test);
}

public Action test(int client, int args)
{

    SpawnButtonFrontOfMe(client);

    return Plugin_Handled;
}


// Get position front of player
void SpawnButtonFrontOfMe(int client)
{
    if(client < 1 || client > MaxClients) return;

    float pos[3], ang[3], fwd[3];

    GetClientEyePosition(client, pos);
    GetClientEyeAngles(client, ang);


    GetAngleVectors(ang, fwd, NULL_VECTOR, NULL_VECTOR);
    ScaleVector(fwd, 100.0);
    AddVectors(fwd, pos, fwd);

    char origin[100];
    Format(origin, sizeof(origin), "%0.1f %0.1f %0.1f", fwd[0], fwd[1], fwd[2]);

    // Flip 180
    float output[3];
    MakeVectorFromPoints(fwd, pos, output);
    GetVectorAngles(output, ang);
    ang[0] = 0.0;

    char targetname[100];
    int tick = GetGameTickCount();
    
    Format(targetname, sizeof(targetname), "@glow_%i", tick);

    CreateModel(fwd, ang, origin, targetname);
    CreateButton(fwd, ang, origin, targetname);
}
