How to render one 360 image into left/right images for the stereo vr?

[ChengHua926]

I render a cube into stereo image in blender, then split it into left/right image using stereophoto maker. The image came out alright but when I put it into the aframe stereo component code, the cube in the image is terribily tilted in the lenses.
