I’m working on a topdown 2D game and I have some AI behavior setup after following the Advanced AI Twitch training video. I’ve rotated all the sprites to align with the XY axes so I could utilize the navmesh for the AI. Everything has worked really well except the AI can perceive the Player through walls. I’ve turned on AI debugging so I can see where the perception extends through the wall. I can inch the player into the AI perception a little without being spotted, but if I move the player fully into the cone of vision he is seen.
Initially I thought it might be a Paper2D issue, but I replaced all the wall sprites with very large cube meshes and it did not make a difference. The AI can still see through the cubes. I’m new to Unreal so I might be missing something, but it seems like a bug.
I tried reproducing the problem in the 3D topdown template and couldn’t so it most likely has something to do with Paper2D.
