How to stop the gas resize field from shrinking down at end of sim


Recommended Posts

Hi Guys,

I have recently started experimenting with Houdini and have stumbled upon a problem I can't seem to find a solution to.

I have a Pyro fx explosion setup and I would simply like the gas resize field to reach the maximum bounds of the container and then switch off. 

Currently, whilst the smoke is dying out, the resize container is scaling back down to the size of the emitter object resulting in a visible bounding box in the render.

Any advice would be greatly appreciated,

Thanks,

Clive

Inside the resize container node there is Reference field. This defaults to density. However, the bounding box of density is often smaller than the heat or temperature around it. You can extend the Reference field by typing temperature after density. Then the bounding box of both volume types should be evaluated for the resize operation. I often increase the padding up from 0.2 default to 0.5 as well.

Worst case scenario you can disconnect the resize container and simply manually animate the Size fields of the smoke object itself.
