I built my first HLDM (none sorce) map and need a bit of help.
I have an area that floods (a brush of water move up) but it leaves a "hole" under the water brush that the player can swim down to and walk around.
What is the best way to fix this so there is no "air pocket" under the water wen it rises up?
2nd question: What is "Lip"? I have failed to find info on the proporties of "Lip". I would like to know what lip is and how it works in relation to water and doors.
