I know you can use Blender for meshes in :ff:, (I've seen some tutorials) but I haven't seen anything for :ffvstr:. So is it possible?
There's exports for either format.
I only use it for FFvTTR.
When you export a .nif file from Blender a dialogue comes up and on the bottom there's a huge block of buttons to export nif types for 34 different games and 34 different versions to the right of that. Pretty much the same order as the FF1 tutorial but select the FFVTTR button on export instead.
