DeePsea

DeePsea is a Doom level editor and WAD resource manager with support for any Doom port via custom configuration files. 3D texture alignment uses a variant of the Risen3D GL port, R3Dedit. R3Dedit is based on a real gaming engine thus provides a realistic view of the level with actual skies, special support as well as optionally showing the placement of all sprites.

It was developed by Jack Vermeleun of SBsoftware and is a Shareware application. There is no time limit, but the maximum size of levels a user can create is limited to 800 linedefs or 1200 sidedefs for the unregistered version. DeePsea's development is ongoing.
