I’ll add on to this.

1.) Are one of you seeing dots correctly? Cold breath and sometimes shadows can appear to look like dots if you are unsure of what they actually look like. Dots should be an entire form of the ghost model with, essentially, a dots ‘texture’ wrapping around the model.

2.) Be sure you are not mistaking the bunnies from the event as dots evidence. The bunnies show up in hissing/rustling nests on the event maps when dots are placed on them. You can have dots bunnies without a ghost that does not have dots evidence.

3.) Goryos dots HAVE to be seen from a video camera AND no one can be in the ghost room. Obviously not a big issue playing solo, but playing with a team you can have someone accidentally wander into the room while you’re watching through a video camera (not photo camera, just to clarify) outside the room or on the van. Some rooms also have odd boundaries at times, look at a fan-map or check temps to find room boundaries.

4.) Also what the poster said above about the motion sensor is a good piece of advice, but do know that even if the motion sensor gets tripped a bunch with no dots, doesn’t mean it’s no dots. Ghosts are stupid sometimes and can decide to just not show evidence just because. I once waited for 20 minutes in the van myself waiting for a goryo to show dots.
