(Not) Between Two Fernes
The VFXer Between Two Pines has released a package with five free looping animations – these are steam and smoke animations in OpenVDB format. According to Between Two Pines, use for commercial projects is permitted.
The smoke clouds and steam squadrons can be loaded into all VDB-capable tools, such as Blender and Houdini – and then rendered out with Arnold, OctaneRender, Redshift or V-Ray. On Gumroad you can smoke yourself – possibly squatting between two pine trees? – in.
