Hi guys. Is there anyone here who is rendering crowds from H in Arnold? Arnold doesn't support packed primitives, so: I'm trying to figure out how to leverage instancing at Rendertime in Arnold so that rendering really big datasets(hair, cloth included) is possible. Are there any smar...

Anyone know the HtoA e... -
