Hi,
I was thinking, if we could put all the structures, units, assets, into Blender. And animate the sequences there.
As for the dialogue sequences, we can use the Warzone map maker.
E.g: Make a map, and add a red dot where the enemy base is. Then in-game, make the mini-map large, and take a picture of it, without the camera icon in the way.
Then import the picture into Blender, draw the details, and animate the Blender camera to move to the red dot.
