about clouds simulation

[f3de]

hi, i'm thinking about clouds simulation without find a solution. I realized some static clouds following the help tutorial. But I need clouds to react with objects passtrought a certain frame.
it is possible to have simulation freezed until something interact?
to freeze simulation I've cloned acache frame and then renamed all, so I have static clouds for all timeline. I cannot find a solution for interactions

Hey,

In order to use a static frame from your simulation, just set the mode to Cache Index in the Input rollout and specify which frame you want to use. There is no need to rename cache files at all.

As for the interaction - you can create a second simulator around the already made cloud. Then create a new Fire source and pick the first simulator with the cloud - make sure that the checkbox "Can pick Simulators" is enabled, otherwise you won't be able to pick it. Disable the temperature so the cloud won't start going up.

Then set the Emit mode for the source to Volume Brush and animate it so that the first frame is 100% and then next one is 0. It's a good idea to hide the Fire source from the first sim or exclude it from interacting with the second simulator from the Scene interaction rollout.

Then run the second simulator.

This way you second sim will be filled with the cloud from the first one and it will remain static until it collides with some geometry.

Hope this helps!
