I half recall coming across something like this before. You need to lock it down, be it freeze it or cache it or something........ I think
Date: Mon, 14 Jul 2014 08:23:04 -0500 From: [email protected] To: [email protected] Subject: XSI hair and Random Generation Is there something about XSI's standard hair primitives (not ICE) that causes the hairs to be generated slightly differently each time a scene is opened? We're rendering with Redshift, but I'm thinking we saw something like this a few years ago with Mental Ray as well. Basically, on the farm, some machines will render their frame ranges with slightly different hair than any other machine. The only solution seems to be to render all the hair on a single machine, and to do so in a way that keeps the scene open (so in the case of Royal Render for instance, set the sequence maximum to be the full range you need). The rendered hair isn't 'bad' per se, it's just 'different' from surrounding frame ranges. The simplest description is that each machine seems to want to render the hair slightly differently. And I really wonder if it's not some bug with XSI hair. -- Signature Tim Crowson Lead CG Artist Magnetic Dreams, Inc. 2525 Lebanon Pike, Bldg C, Suite 101, Nashville, TN 37214 Ph 615.885.6801 | Fax 615.889.4768 | www.magneticdreams.com [email protected]
