From 5b97c00e9fc4e1e5d6cdfa7130eab5aada0e068e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?K=C3=A9vin=20Dietrich?= Date: Thu, 19 Aug 2021 14:13:45 +0200 Subject: Alembic import: option to always add a cache reader The current behavior of the Alembic importer is to only create a `MeshSequenceCache` modifier or a `Transform Cache` constraint to imported objects if they have some animated properties. Since static objects do not have a cache reader, when reloading files those objects are not updated. Currently, the only way to properly reload a file because of this is to reimport it. This adds an option to the importer to always add a cache reader, even if there is no animated data, to ensure that all objects coming from Alembic archive are linked to them and updated properly upon reloads.
