hi , i having a problem which is how to render or cache hair animation in render farm(render farm only support v1.08).

i got diffirent result which the local render looks good.but when i sent to render farm the result are like flicking jump frame(becos of the moov physics).

And when i do an animation cache, i reimport in it does not content animation.

is there any way to solve it?

Hi,

What are the differences between rendering locally and on the farm? If you perceive hair flickering when rendering on the farm this is because you need to turn on Remember Roots Positions in Hair from Guides. If you are rendering the Alembic Cache then make sure that all the machines in the farm are loading the cache correctly. My guess is that they are loading the cache at different times and frames. 

THis is assuming that this is the same issue that was reported on Facebook.

Hello Wystan,
I also have problem with "Animation Cache" modifier and Alembic export is crashing (working with "Guides From Curves" on long female hair).
If you manage to solve your problem please write down the workflow.
Thanks in advance.

Hi,jeo

i notice cinema4d cannot collect the asset(the alembic file that baked out) from ornatrix operator.That is why when i collect to render farm for render,the outcome with no hair effects.I am using ranchcomputing as my renderfarm.The only way to upload the file which need to use their c4d plugin to pack it and i cannot store or copy file into it(a VUC file that content all the c4d project asset,but it does not recognize ornatrix pointing path for alembic file,same as cinema4d as well).Is there anywhere to solve this?
