cgartashish posted a topic in EffectsHi, Whenever I run a pyro cache, that is, I import the pyro fields and attach a fileCache node and write out the cache. The simulation eats up all my RAM as soon as the caching starts and then almost freezes my system. I always check off the cache sim option in DOP node that disables saving cache in RAM, but even then my RAM quickly gets filled up. I have created a basic pyro explosion not very large scale and I have 32 GB RAM. Is there any way to control or limit how much RAM Houdini uses for simulation? Like say, use 28 GB RAM and no more or flush previous cache from RAM automatically. Thanks
