Fresh arrived here at Insect.Digital.Alchemy, the pyrofx asset for Houdini. It comes ready with a setup and shader scene file and can be used commercialy. Please watch the promotional material to see what this explosion looks like. The scene file ships directly after the payment and is readable in all Houdini versions as its a *.hip file.
Ships ready also for the newest Houdini 17 builds, as we tested this recently in that environment.
