The adds a new option to simplify volumes in the viewport. The setting can be found in the Simplify panel in the render properties. Volume objects use OpenVDB grids, which are sparse. For rendering, we have to convert sparse grids to dense grids (for now). Those require significantly more memory. Therefore, it's often a good idea to reduce the resolution of volumes in the viewport. Reviewers: brecht Differential Revision: https://developer.blender.org/D9040 Ref T73201.
