Breda I'm not sure, but with Saxion you're only taught in Unity. But if your team/project allows it, you're allowed to use other tools in certain projects in some 2nd/3rd/4th year projects. You're fully allowed to make game assets in Blender, and it's encouraged to test it out to see how you like 3D modelling. Within the program we use Maya, but it's not a hassle to use Blender in these contexts.
