We are going to start by creating a growth attribute that will be the main driver of our FX.From this attribute we will be able to generate a growing VDB mesh, and the laser Rays as well.We are going to set up different custom attributes to help later with shading.We are also going to generate smoke where the laser creates the geometry, and also create a simple fog volume to add a bit of ambience to the scene.Aside from the Helmet geometry which will be provided, we are going to create everything from scratch directly inside Houdini.
