We have implemented a Portal Occlusion culling for our game with the Room and RoomManager nodes. Everything works but the Particles don't show. Reading the docs we have seen the section concerning this exact problem.
Our problem is that the two solutions that are proposed don't work for us. Both setting the portal mode to DYNAMIC and setting a cull margin don't work for us.
The only thing that has the particles show up is either setting the Portal mode to GLOBAL or ROAMING. Both of these options make our game perform much worse. Is there maybe something we are missing about the system?
