Water and displacement brushes

I made a map with a displacement brush underneath a water brush, and underneath both of those is a skybox brush, and the whole thing is in a skybox

|``````skybox`````| |/\/\displacement/\/\|
|_____skybox______|

The displacement brush has it's geometry going INSIDE the water brush so the sand under the water isn't boring.

I have a large square room with 8 water brushes around the edge and an island in the middle.

My problem is, if i compile without the water turned on (vis grouped), my map works. But if I compile with the water turned on HL2 crashes. What is causing this?

It gives me an error saying "CDispInfo::UpdateLightmapAlpha - out-of-bounds lightmap alpha data" and also "DispInfo_loadDisplacements: dispcounts (8 and 9) don't match."

8 and 9 are two entirely separate displacements. 9 is part of my 3d skybox.

I dont know what this means

Try not putting a sky box under the displacement, instead just put a nodraw to seal the map.

Agree with rs6, encountered same problem

yup... displacements dont seal anything.. they basically cover an area.. but light and water can leak through them.. you need to put something underneath the displacement surface...such as a no draw texture... and i am not sure if or why u need a skybox texture underneath everything? can the user see the sky box from the ground?

displacement didnt work with my water either...
