I am using UE5.1. I have an opacity mask set and the landscape visibility tool works for visualizing where a hole in the landscape should be, however the collisions are intact on the landscape. basically, I can see through the hole but the player cannot cross through it. Strangely, it happens about half of the time I create a hole. Does anyone know how to fix this?
Try moving/dragging the landscape to a different position and see if the problem persists.
If it does, please post a photo of your material function.
Worst case scenario, you can delete the landscape tile (assuming it isn’t huge.)
I’ve found that if the visibility hole is too small it will have collision still overlapping it. Especially when on the side of cliffs or other vertical landscapes where the collision gets a bit stretched. Try making the hole in the landscape a little bigger until the collision opens up, and then use some static meshes around the opening if you need it smaller.
There might be a better fix, but I haven’t been able to find it, so this is a least a workaround that has worked for me
