xgen interactive fur popping when rendered on farm

Hi,

I have this asset that has its fur groomed using interactive xgen. Upon batch rendering on the farm, the fur sometimes goes completely missing or gets stretched at random frames.

stretches at random frames

I am using Maya 2017 update 4 with MtoA 1.4.2.3 ( Arnold core 4.2.16.4 ). The xgenToolkit is the default that ships with Maya

At frames where the fur goes completely missing ( usually the first frame of the sequence ) I can see these errors -

and at the end of log I see these errors

Error: line 1: XGen: Invalid binary stream. Expect a Header tag.
Error: line 1: XGen: Invalid binary stream. Expect a Header tag.

The frames at which fur strand renders stretched there are no 'Failed to load sample' or invalid binary stream errors but the number of points are still invalid.

Hey @Saswat Sahoo, I'm working on a short where I had a similar issue. I had fur made with Orantrix and the fur had issues on the render farm. It turns out that it was a surface comb node which rendered fine locally but on the farm it would make the far pop or move. Also Ornatrix has a remember root position that locked the guides in a certain spot. Maybe you can apply that to xgen. Also xgen might be dependent on certain types of mesh. I know that a wrap deformer does not work well with xgen. If your using a rig try baking out an alembic. I've even referenced an alembic and used it to trick nHair to calculate it's transformation. Then you can switch out the alembic for each scene. Let me know if this helps.

Good Luck
