Hi !
I finished the first iteration (the first because it does not support yet air units, different type of attack, upgrades etc ...). Also, it is not stand-alone, it must be installed in an Eclipse Modeling Tools.
I can easily create a faction like in the picture (click on "create a building" create a blue square, I can change its name, its attributes, etc ...), and with a right click on my faction it generates the directory to paste into techs folder.
Regarding animations, I can indicate for each unit to use the animations of an existing unit in Megapack (I have a script that will search all the values of a techs folder). So I can easily make a prototype, before creating specific animations.
I agree that it can rocketblast increase creating mods!
But what do you think about the idea that instead of several people each develop a mod, each develop only a faction and duels each other!?
