- Additional grids for UV: here you can specify names of other grids usually found in VDB file that describe velocity or temperature, or any other data that was calculated during a simulation (such as particle distance, acceleration etc.). Use a comma to separate the different grid names. These grids can be used to map textures, usually a colored gradient, to better visualize the stored data. For example if the VDB file contains a "temperature" field, this means that the different temperatures of the simulation grid is stored in the file and you can use it to visualize these different temperatures using a blue to red gradient that uses this field as a driver to create the necessary UV map when rendering. Please see the "Texturing OpenVDB volumetrics" below for more details.
- VEC_MOD 0 to 9 min/max: Lets you redefine the range of the corresponding vector grid, before it is normalized to 0,1 space for UV mapping. VEC_MOD_0 corresponds to the first vector grid found in the file, VEC_MOD_1 to the second one and so on.
- FLOAT 0 to 9 min/max: Lets you redefine the range of the corresponding scalar grid, before it is normalized to 0,1 space for UV mapping. FLOAT_0 corresponds to the first vector float grid found in the file, FLOAT_1 to the second one and so on.
