Now, The map i am doing is a port of a current DOD map, After i loaded it up, and decided to redo the entire water section, with a displaced bursh. I had a load of leaks and whatnot, i fixed all of them, and no more leaks.

I also have the relevant entiries in place for the water ( env_cubemap & water.lod.control )

The water only shows up like that ingame and also only on MY map (and any map for that matter that I compile.) All other HL2/CSS maps i have with water in work, so i dont get it!

I have also run "buildcubemaps" not that it would matter on my system as i am running an ATI9800pro which is DX9 compatable.

your screenshots dont resolve as with the rest of the links on this board.

you dont make water out of displacements

just a brush with all sides bar one covered in no draw, the top side covered withwater texture

is the cubemap tied to the water brush, or just floating above it.

The cubemap entity is tied to the water surface yes.

Also the water isnt displaced, its a solid brush which just has the surface textured as nodraw and the top with the water texture.

Problem solved, turns out there was still the entity func_water assigned to the brush as well. Which was used on the current version of the map, not the port to source.
