If I play a simulation, it is cached to disk. Is there something like a disk cache node, which I can use if I want to use a previous created cache? Can I name the cache so that I can create several different caches to check different settings?

Sure. See the File DOP operator.

Change “Operation Mode” to “Read Files” and point it to your files previously saved on disk with the same operator set to “Write Files”.

So, basically you create simulation and finish a network with File DOP set to Write. Then you create another FileDOP and set it to Read.

voila!
sy.

Try reading up on the File DOP. I think the easiest thing to do is to append it to your last DOP and make it the new display DOP. Make sure the path is correct and then set the Operation to Automatic.

Cool, thanks.

i also noticed a setting for ‘explicit cache’ in the DOP node at the obj level. also had to uncheck the ‘automatic resimulation’ box.
