I have a sequence of OBJ files that I am importing into 3DSM. They are loaded in so that OBJ_0 equals frame 0, OBJ_01 is frame 1 etc. Clicking through the timeline shows the animation of the object. I have exported this as an FBX, with baked animations selected. But when I import this FBX into Unity, there is no animation, and the object is simply stuck on a single frame. What are the criteria for (baked) animations in order for Unity to correctly import and show the animation?
