From 071f4f4ce0b9520ab0c73d6d68365ad449ca8b80 Mon Sep 17 00:00:00 2001 From: Stefan Werner Date: Fri, 23 Nov 2018 13:08:15 +0100 Subject: Cycles: Improved robustness of hair motion blur. In some instances, the number of control vertices of a hair could change mid-frame. Cycles would then be unable to calculate proper motion blur for those hairs. This adds interpolated CVs to fill in for the missing data. While this will not necessarily result in a fully accurate reconstruction of the guide hair, it preserves motion blur instead of disabling it.
