Ornatrix Maya: Fur Disappears if Arnold Motionblur Keys setting is set to an odd value

Hey, I was stumped by some odd render results and found that if Arnold motion blur is enabled and 'Keys' is set to an odd number the fur renders incorrectly, but on even numbers it renders fine. I was able to replicate it on a furball in: maya 2019 ornatrix 3.2.3.27923 MtoA 4.2.3 motion blur details: Enabled True Instantaneous Shutter False (though the issue also occurs with it on) Deformation True Camera True Shaders False Keys 3 (or any odd number) Position Center on Frame Length 0.5

Jeordanis Figuereo	HI, Recently we added support for Motion Blur on our Arnold Procedural. Please try the latest stable build and let me know if the problem persist. https://ephere.com/plugins/autodesk/maya/ornatrix/forums/builds/thread_13795.html Jeordanis Figuereo (Product Designer.

IvanKolev	The procedural isn't ready for production use yet, and it only supports 2 motion keys for now. But I doubt that you are rendering through the procedural. This looks like an issue in the common Arnold export code that we'll have to investigate. Ivan Kolev (Software Developer, EPHERE Inc.) E-mail: ivan.kolev at ephere dot com Discord: ikolev

PatrickSi	This was with procedural off. Its low priority and easy to workaround, just an oddity that I thought I should bring up.
