Rain in Caves - Missing Riparia POIs List

Hi, I'm testnig rain in caves and I'm drafting a list of the Subpois where it's still raining. Format is Name and I'lla attach screenshots of the map so that I can show the position

• Redwood cave 2 towards hollow hills (even deeep inside)
• Hollow Hills "cilseum like" stone structure
• Redwood cave 1 towards SW corner of the map (this one was weird it didn't rain at the start but after waiting 5/6 seconds it began)
• Redwood small cave center of the POI (ish)
• Blackfern Hills Rainbow Falls cave
• Pride rock 1 DFC. (this one is hard ro replicate, basically when you go the first time through it it works fine, then you stand on the edge where the rain starts, come back in and the rain will stay there)

this is what I could find in the west side of the map. Will update later with more testing if I can

Rain goes through the walls

Rain doesn't go through solid objects
