Render: faster animation and re-rendering with Persistent Data For Cycles, when enabling the Persistent Data option, the full render data will be preserved from frame-to-frame in animation renders and between re-renders of the scene. This means that any modifier evaluation, BVH building, OpenGL vertex buffer uploads, etc, can be done only once for unchanged objects. This comes at an increased memory cost. Previously there option was named Persistent Images and had a more limited impact on render time and memory. When using multiple view layers, only data from a single view layer is preserved to keep memory usage somewhat under control. However objects shared between view layers are preserved, and so this can speedup such renders as well, even single frame renders. For Eevee and Workbench this option is not available, however these engines will now always reuse the depsgraph for animation and multiple view layers. This can significantly speed up rendering. These engines do not support sharing the depsgraph between re-renders, due to technical issues regarding OpenGL contexts. Support for this could be added if those are solved, see the code comments for details. |
