I have a Samsung gear vr,
So the way I do it now is by exporting my model to obj and importing it in blender.
In blender I render an image as a panoramic image and then view it with 360 photo viewer on the gear vr.
I really want a way to walk around in the model.
one option I am exploring is to use unreal engine to make a simple game for gear vr and then importing the model I want to view.
