Sound propagation without zoning.

Is this possible?

I have static mesh which is an enterable house. One story, the doorway is cut and the door mesh aligns perfectly. Its floor is bsp, ai has no nav-mesh problems with it.

However, I can't zone inside of the house since it's mesh. You can hear the sleeping people inside when you get close, or they're alerted easily when walking around the house.

I tried wrapping volume around the house mesh with sound property bOcclude=true, that didn't work.

Any suggestions?

That's an easy fix: you can zone it. BSP boxes with the BF texture, and some part of the smesh sticking into the zone. So long as the smesh is in the zone (partially) it will render, and because the walls are BF you won't see them - effectively looking through the "wall" to see the staticmesh.

Thanks a lot, I was expecting a solution without bsp. Because in this way I have to cut out doorways & windows.

Also I just realized when there is zone inside another one, the smaller zone's sound radius in the zone properties window is not shown.(that bright orange box)

The orange box effect only highlights bsp surfaces as far as I remember, so you may just not be seeing it. As long as the bsp is different colours in the zone/portal view it should actually work okay whether you can see the orange effect or not when changing that stuff.

I don't think there is a solution without bsp as such - the static mesh option for blocking sounds is for use *with* bsp as far as I know (which isn't as much as I let on :p), like for doors when they're closed or windows you wanted people to listen through or whatever.
