Ah. After the copy. Of course, because the orientation wouldn't be updated. Thanks Tomas!

I'm getting some odd results whilst simming some tufts of hair.

I'm copying the tufts onto some scattered points and then testing with gravity. Instead of the tufts falling straight down, I get an odd push along the positove Z axis which leads to an un-natural look.

I cannot figure out what is causing this. I've tried the simplest setup I can think of and I still get the odd result. I've attached and example file and any insight would be great.

Ok, so this is fixed by turning on Allow Shader Parameter Animation on the materiallibrary LOP🤦
