Object used for particle render getting direction flipped when particle system applied to target with curve modifier Im trying to setup a modular conveyor for animation using the method shared here: Setup Constraints for modular conveyor. However the object used to render the particles is getting its direction flipped halfway round the curve. This results in the ends not matching up.



Is there a way to fix this? The blend file can be downloaded here.
Look at https://blender.stackexchange.com/a/172271/35559 for some updates or possible fix.

Meanwhile, not really sure what's happening but even on a simple non cyclic curve, you can see the beltlink flipping orientation as it moves along the Y axis as soon as it reaches a curve control point (which is aligned and "flat"). May be a bug, something linked with the way curve control points are impacting the Array Modifier...

For some reason, it does not behave that way on all control points.
