Isometric camera view remove object between player and camera

Im making a isometric 3d game. World is generated procedually and the world can be multi layered. So i have many places where one dungeon part is above another. But I dont want to see the dungeon parts that are above the player. I tried moving the camera closer to the player, so that if i move the camera would be underneath the parts above, but then i get these near plane clippings. I tried to change the size of the camera, but this zooms in and this is not what i want. I also tried to use oblique frustum clipping, where the clip plane is above the player, but i cant get the clipplane working, either it guts too much or messes the vie frustum up.

Anyone know how i can make so that the layers above the player are not shown(also wont interact with raycast)?
