Object orientation is not right #4272

I have a problem which the object I loaded using createvisualShapeId and collisionShapeId seems to be standing like there is an invisible spring there (I am guessing the orientation is wrong?). It supposed to be laying down on the flat surface.

Why does this happen? does it have anything to do with my OBJ file that I created in Blender? This is my code for loading it: `shift = [0, 0, 0] meshScale=[obs_size,obs_size,obs_size]

creating stackable tool:

visualShapeId = p.createVisualShape(shapeType=p.GEOM_MESH, fileName="stack_5.obj", rgbaColor=[1, 1, 1, 1], specularColor=[0.4, .4, 0], visualFramePosition=shift, visualFrameOrientation=[0,0,0,1], meshScale=meshScale) collisionShapeId = p.createCollisionShape(shapeType=p.GEOM_MESH, fileName="stack_5.obj", collisionFramePosition=shift, meshScale=meshScale) stack_list=[] for stack_position in stack_coor: stack_list.append(p.createMultiBody(baseMass=50, baseInertialFramePosition=[0, 0, 0], baseCollisionShapeIndex=collisionShapeId, baseVisualShapeIndex=visualShapeId, basePosition=stack_position, useMaximalCoordinates=True))`

if or not the simulation time is too short.
