Ok, running 2.5, Alpha 2, 27226.
Ran a Smoke sim, renders fine while cached. Baked the cache, re-saved the scene.
Exited Blender, relaunched Blender with saved scene – all the Baked frames load fine.
Tried another frame render, NO SMOKE! And no smoke showing in the GL 3D view either.
Is this a bug?
Does the domain material and voxel texture need to be re-entered manually?
Do I need to rebuild a new cache with Alt-A (starting over!) or will the regenerated cache use the already baked data?
