Im the creator of the Battleforge Blender Plugin to import and export DRS files. And as we all know Spellforce 2 DRS files are kinda similar with extra salt. Anyway, I ported my plugin into a new project just for your Spellforce 2 needs.
You can find it here: https://github.com/Maxxxel/SF2-ImpEx-for-Blender
It's an ongoing project and as I'm not a SF2 Player, I need your input.
What you wanna do? Tell me and I try to make it possible.
At first I want to make every single drs file and animations readable. Try the plugin, if a file import fails -> create an issue and I'll fix it.
Second, I will add SKA Export, so you can change the animations of existing models and create new ones, easily update the AnimationSet file for variations etc.
At last, I may take a look at exporting new units (static objects/props should be doable with no big effort).
Whatever you need, create an issue and I'll take a look. Keep in mind that I fully work on the Battleforge plugin, so SF2 Plugin Updates may take some days.
