Description

One cannot completely blind the user via RLV. Viewer fails to show appropriate visual effect.
Fails on both collar and muzzle, but tested here using the muzzle.

Tested using a muzzle outputting the following:
[02:38] redwes's sight is now completely blocked.
[02:38] Canis Muzzle (Unrigged)(pink metal): executes: @shownames=n
[02:38] Canis Muzzle (Unrigged)(pink metal): executes: @showworldmap=n
[02:38] Canis Muzzle (Unrigged)(pink metal): executes: @showminimap=n
[02:38] Canis Muzzle (Unrigged)(pink metal): executes: @showloc=n
[02:38] Canis Muzzle (Unrigged)(pink metal): executes: @setenv_scenegamma:0.0=force
[02:38] Canis Muzzle (Unrigged)(pink metal): executes: @setenv_densitymultiplier:0.0=force
[02:38] Canis Muzzle (Unrigged)(pink metal): executes: @setenv=n
[02:38] Canis Muzzle (Unrigged)(pink metal): executes: @setdebug_renderresolutiondivisor:-1=force

Reproduction steps

1. Equip wearable object that can "blind" user via RLV (collar, muzzle, etc).
2. Activate function that triggers rlv "blind" commands ("blinder blind" etc),
3. Watch for results-- screen will either blacken (as per Firestorm) or fail to.

Realistically creations like this should rely on actual blinding mechanisms built into RLVa, they should always function correctly because they are not just tweaking at rendering setting knobs in the background hoping to reach their expected results.

e.g. this sample which reliably fully blinds the user
@clear=camdrawmin,clear=camdrawmax,clear=setsphere,setsphere=n,setsphere_valuemin:0=force,setsphere_distmin:0=force,setsphere_distmax:0=force
