I want to produce a fire animation in Blender that cycles, the first frame being the same as the last.
I've tried following a youtube tutorial Looping Smoke-sims in Blender | Quick Tip on Simulations but I can't get the procedure to work.
I'm wondering if it's possible to manipulate vdb caches, either from within Blender or via stand alone tooling.
Suppose I have a cache of 250 *.vdb files, corresponding to 250 frames of animation. Frames 1-50 animate the fire starting up and frames 200-250 animate the the flame dying out. These effects I achieve by keyframing the fuel for the Flow object.
What I'd like to do, within Blender, is to take a create a volume Add>Volume>Import OpenVB and import to it frames 50-250. Then somehow 'merge import' frames 1-50 into that same newly created volume, but starting at frame 200 of the volume. That way, the start of the volume should be identical with the end without any discontinuity in between.
I can't see any such menu in Blender to do that however. Nor can I see any option to join volumes, in the same way that objects can be joined.
