In this small tutorial we will create a smoke simulation with pre-roll, that is a cache on the negative frames in order to run the simulation for a specified number of frames prior to the beginning of the actual animation. Because of that the smoke/fire will be already initiated when the animation starts.
I’ve found those questions online and decided to write a tutorial about it, so if you are interested about the original istructions you can find them here:
Blender is a great tool but sometimes it will disappoint us, not because it lacks some functionality, but because for some features there is a functionIsThereButWorksOnlyAfterBlackMagicActivation feeling…
I’ve worked with simulations in the cloth, fluid and rigid body field and the ongoing revision of the physic system is a really great and challenging task for the Blender foundation (did you said tornado in project gooseberry?)
Well, my new kryptonite was is the smoke simulation and its parameters.
In order to do a bake of the smoke domain with a pre-roll of 100 frames(that is sufficient for my purpose, change it for your own task) you have to follow those few simple steps:
Let me know if you encounter any issue!
