best approach on interactive cloud effect ?

[KenBee]

Hi there,

I want to know what is the best approach on creating a large scale of stratus cloud and have an airship drop through it ?

- I was initially starting out with 5000 x 5000 m box and shape it using the cloud node and cloud noise node as the background clouds

- Then I created a smaller piece of cloud for simulation using pyro solver for the interactions between the clouds and the airship

But when I try to up sampling on the cloud node for enough details for the background stratus cloud, houdini crashes every time

I was wondering for the bg clouds if I should make it smaller and instance them, or if there are any better approaches to tackle this effect?

Thanks in advance!
