Hi this last years i have playing with diferent editors and engines, id tech engines with all radiants , iw radiant, cryengine... I working now with this editor "DarkRadiant" look like best than real doom 3 editor, but in id tech radiants, i dont see a utility for terrain or blend tool and this tool is very useful, now i post how works this tools if like put in the DarkRadiant and other ideas. The Basic Terrain/Patch tool like IW Radiant, for move massive vertices in the patch using the 3d camera window in the editor. (Only for patchs) (For fast change the height of terrains with (Height / Flatten /Smooth...) (3D basic brush in 3d camera window of editor) *In the photo the green is the patch editor window with the options, and the 3d brush in the 3d window The Blend tool, only for patch this use the same tool for change height with different config, using the brush 3d for change the opacity from 100% to 0% with vertices reference. (for decals of terrain and walls decals...) Here info of cod5 http://wiki.modsrepo..._Alpha_Blending (not by me) Other ideas: Add more options of divisions in patch terrain for 2 to 30 all numbers (no 3 to 15 with some numbers). Add grid 512 option. BSP menu like doom 3 editor with the options for compile... 2 Buttons for auto drop the entities (1 for drop the select entitie to floor (brush or patch) in Z axis and the 2 button = but change the angle). *In the photo the blue circle. Textures like clip... option to make semi transparent in the editor 3d view Option for 2d view at move in this view the display names hide and some entities hide for no lag at move the 2d camera For DarkRadiant and mod: Option of basic collision particles (like quake 4 ?) collision with ground, for sparks for example. Thanks.
