New postPosted: Tue Feb 20, 2007 8:05 am    Post subject: Unofficial Supreme Commander Map Editor v0.46 BETA

It is here, the first (inofficial) map editor for SupCom!

What it does:
- Edit terrain and texturing of maps (real 3D display of the terrain)
- Add/Remove/Edit start locations, mass points, AI markers, etc.
- Add/Remove/Edit Decals and Props to decorate your maps
- Resize Maps
- Restrict build options on a map

What it does NOT do (yet):
- Editing of Singleplayer missions (only multiplayer maps for now)
- Adding units or wreckage to a map
- Individual scripting

BE AWARE that this is just a Beta version. There might be errors, bugs, crashes and maybe even corrupted files. You are using this at you own risk! (I don't expect any massively bad things to happen, but you never know. Very Happy )

Since the editor supports the full SCMAP format now, the loading times and the memory usage have increased alot! Especially on larger maps it does need alot of (Video- and System-)RAM. Functions like Resize, Load/Save and Import/Export may need a while to complete. Just don't panic when the app freezes for some time.

The overall performance is quite bad! Loading times are horrid and the whole thing runs SLOW. I haven't done ANY optimizations yet! In example a 80x80km map is rendered in full detail with all of its 33.000.000 polygons... Laughing There is a lot potential for optimizations.

Download version 0.46 Beta HERE!


This tool requires the .Net Framework 2.0 and at least
the DirectX 9.0c November06 update to be installed on your
PC. If the application crashes or behaves in an unwanted
manner then download and install those updates.
