Can't match an OBJ and a MDD outside Houdini. Was the OBJ exported changed or user error?

[probiner]

I tried to match a MDD and an OBJ exported from Houdini in several apps, but always failing. Here in Blender, on the left, the OBJ. On the right, a correct match of what I see in Houdini, exported with another format.

OBJ was exported with Right-Click > Save > Geometry > OBJ
MDD was exported with ROP MDD Point Cache.

Scene file used attached.
Let me know if you see the same. If so I guess I'll file a RFE.

Cheers

I think it's gwavefront strikes again. Also, fixing importing issues on spheres doesn't help much.

Try .ply instead. gply utility reversing geometry for some reason, so, reverse geometry before exporting.

Thank you for looking into it. What's the problem with spheres?  I did have another more complex object, so I tried to isolate the problem this way,

PLY is what I used on the working sphere. thanks for the flipping heads up!
Another thing that worked, was using https://github.com/heimlich1024/OD_CopyPasteExternal

I tried your test file and it worked fine for me in Blender 2.78c.

The only thing I may have done differently is that I dropped down a ROP Driver at the end of the sphere and kicked out the original .obj from that node instead of using any File/Export options.

Thank you for looking into it, but from your image I think I can see the same problem. Notice that I'm looking from the top in my gif, not front. I guess this is what @f1480187 was warning about

Cheers
