Minor update on scmdraft 2.0 - isometrical terrain perfectly working, square and rectangular terrain placing also working with various sized brushes without affecting isom layer, however placing a border over square terrain *may* have sideeffects, hasn't been tested.
once doodad code and save code is added an alpha build will be released with full terrain editing capabilities(projected ETA: 1-2 weeks max, until then here is a screenshot, also here and here.
Feel free to email me suggestions for scmdraft, however i may not have time to reply. Please don't send mail regarding scmdraft 1.0 beta as this is a new codebase and therefor the older version will not receive any updates.
