Hiding UIs behind a custom image shader

Is there a way to hide UIs such as text, images etc. behind another transparent image? The problem is that I am using the latest Unity version and these custom shaders have no effect on hiding the UI shaders. The two custom shaders I have applied for testing are:

Shader "Custom/DepthReserve" {     Properties     {     }     SubShader     {         Tags { "RenderType" = "Opaque" "Queue"="Geometry-1" }         LOD 100           Blend Zero One           Pass         {           }     } } 
Shader "Custom/InvisibleMask" {   SubShader {     // draw after all opaque objects (queue = 2001):     Tags { "Queue"="Geometry+1" }     Pass {       Blend Zero One // keep the image behind it     }   } } 

So is there a way to use a transparent image to hide text, images and even gameobjects?

Can you retroactively increase your Stealth roll while hiding?

The rules for hiding (PHB 177) has an interesting clause, which makes it distinct from many other contests.

When you try to hide, make a Dexterity (Stealth) check. Until you are discovered or you stop hiding, that check’s total is contested by the Wisdom (Perception) check of any creature that actively searches for signs of your presence.

Here we have a contest where you make a roll at one point in time, then at later points in time that roll’s result is contested by another party’s roll.

Is it possible for someone who is already hiding to increase their Dexterity (Stealth) check total without re-rolling their check? Possibly by application of guidance, pass without trace, Epic Boon of Fate, or a similar ability? Or is the check total immutable once the initial check has been made?

What are the mechanics for hiding something that is not yourself?

How can a cleric hide a living body? asked for cleric spells that would keep the body of an unconscious but live comrade unseen.

I considered Pass without Trace, since it targets creatures with no requirement that the creatures be conscious, but then realized that if the companion was unconscious, it could not make a Stealth check, so a +10 bonus to no roll is still no roll.

That got me thinking of the larger issue of hiding things that don’t get their own checks. Hiding a conscious character (as in preparing an ambush) would be the Help action, providing advantage on the other character’s Stealth roll. But what would you do to represent a character trying to hide something that didn’t get its own rolls?

  1. Is there an established mechanism for this? (I haven’t found any). Looking for something would be a Perception or Investigation, but what would this be contested against?

  2. I am thinking this would be a Survival check, possibly Sleight of Hand for anything small enough to fit in one hand but that might presuppose active observation while trying to hide it. Thoughts?

  3. What sort of conditions would be sufficient for giving the character hiding something a circumstances bonus (advantage)? One would be abundant time…so how long?

Animal Companions hiding, searching, and readying an action

The PHB has this to say about Animal Companions:

The beast obeys your commands as best as it can. It takes its turn on your initiative. On your turn, you can verbally command the beast where to move (no action required by you). You can use your action to verbally command it to take the Attack, Dash, Disengage, or Help action. If you don’t issue a command, the beast takes the dodge action.

My question is, although it specifies that movement takes no action while a list of actions take your actions, can a Ranger also verbally command the beast to hide, search, or ready an action (that isn’t in the list of actions that take your actions)? Nothing in the feature specifies that you can’t order the beast to take any of the other actions listed.

Hiding in a crowd / Hiding behind multiple creatures

When it comes to stealth, 5e is very vague on what can or cannot be done.

If we refer to the rules as written:

You can’t hide from a creature that can see you,… (PH. p177)

This means that being in partial cover doesn’t grant you hiding potential since others can still “see” you.

So following this thinking, you couldn’t hide behind a target since you would get half cover and could still be seen. What about hiding behind two consecutive targets? Could a DM rule that it would provide an improvement toward 3/4 cover? But then again, one could still be seen since it’s partial cover… But what if you are behind multiple (3+) consecutive targets? At what point can we say that you are behind enough covering targets to provide a total cover?

Imagine an Assassin’s creed type of scene where the hero is concealed and breaks line of sight by hiding in a massive crowd. It would definitely be an interesting scenario but the rules on hiding as they are make it difficult.

So my question is in two parts:

  • Do you think by some DM ruling, it would be appropriate to allow multiple creatures to provide enough cover to completely hide someone?
  • What would be a balanced ruling to permit such stealth play?

If I am hiding and moving silently at the same time, what is my total movement penalty?

In D&D 3.5, according to page 79 of the PHB under the move silently skill:

You can move up to one-half your normal speed at no penalty. When moving at a speed greater than one-half but less than your full speed, you take a –5 penalty.

And, according to page 76 of the PHB under the hide skill:

You can move up to one-half your normal speed and hide at no penalty. When moving at a speed greater than one half but less than your normal speed, you take a –5 penalty.

Assuming:

  • I have no special abilities that have any relevance to this circumstance

  • I am able to move silently and hide in the same round

  • I wanted to do this without incurring a penalty on my skill checks

  • My normal movement speed is 30ft

Would my speed, which I have opted to reduce, be to 15ft or would it be 7.5ft?

Passive Perception or Active Perception Check to detect hiding enemies?

I’m DMing for a party that constantly says stuff like we’ll walk slowly and carefully, or we’ll look around as we walk, to make sure there’s nothing threatening or out of the ordinary.

Say there’s a monster hiding near the PCs (stealth check 14). All the PCs have a passive Perception lower than 14.

Given the above statement by the PCs, should I now ask for an active Perception check to see if they spot the monster hiding? Should I always ask for an active Perception check from now on, since they’re always being careful? On one hand, they did say they were being careful and looking at their surroundings. But on the other hand, I feel like that’s already assumed, as a party of adventurers wouldn’t just nonchalantly walk into a dungeon – therefore I feel like this is exactly what passive Perception is for.
