Baking Smoke Simulations

    is used to store the outcome of a simulation so it does not need to be recalculated.

    Smoke baking settings are in Properties ‣ Physics ‣ Smoke ‣ Smoke Cache.Unlike most physics simulations smoke physics has some settings that are specific to smoke.

    File format that the cache data is to be stored.

    OpenVDB

    Advanced and efficient storage method developed byDreamWorks Animation.

    The simulation fields can be found in the files under the following names:

    • "color"
    • "density"
    • "heat"
    • "heat old" (the temperature at the previous frame)
    • "flame"
    • "react" (reaction coordinates, used for fire)
    • "velocity"
    • "shadow" (the shadows of the volume computed for viewport rendering)
    • "texture coordinates" (used for turbulence)
    • Compression

    • Method of data compression.

      • Zip
      • Efficient but slower compression method.
      • Multi-threaded compression with about the same quality and size as Zip.
      • None
      • Do not compress the data.
    • Data Depth
      • Float (Half)
      • Half float (16 bit data). Gives less data with the benefit of smaller file sizes.
      • Float (Full)
