DescriptionCustom tool which allows you to drive your pyro sim instead of a regular gas wind dop.
To use the otl, import it into your houdini scene (install and create it), press tab then write custom wind, drop the node (Screen 1)
The following screens (from 2 to 6) shows you the different settings of the otl, basically you have a box (screen 2) that represent the bounding box of the volume. The idea is to copy paste relative references parameter of your pyro bouding box values to the box of the tool (but you can put your own value too) because your entire pyro sim will be affected by the wind. The grid (screen 5) is used to visualize the velocity field so the more division you add the more streamers you'll have.
To connect the wind into your pyro dop, you have to add a source volume, pick the null called "OUT_CUSTOM_WIND" (screen 7), disable temperature and source volume, and play with scale velocity!
