Something that blocks AI vision but not player

[Springheel]

I know this has been asked before but I can't remember if anyone has solved it. Is there anything that will be invisible to the player but will block AI vision? Can AI see through textures with alpha channels? IIRC they can't, which would mean that a decal could theoretically do it.

Ah cool, that works. I tested a patch with a readable decal on it. The AI could not see through the transparent part of the decal, but he could walk through it.

 

So if you want to block AI vision but not the player, make a patch and position a decal so that only the transparent part is visible (note this won't work with dirt decals or others that blend with what's behind them).

 

I'm planning on using this to keep AI from noticing missing loot if they're coming from a particular direction.

Sweet.

Any suggestions about where to put it?

I don't see any articles which it could become a subarticle of, so perhaps a new (short) article called "Blocking AI Vision". Linked to "AI".
