Generating hair LOD using Generate Guide Data Modifier 

In this quick tutorial we will go over the Generate Guide Data Modifier in Ornatrix 3dsmax and use it to add and remove hairs based on how far the object is from the camera. This technique can be useful for setting up characters which are in the background while saving memory and speeding up the renders. General Generate Guide Data overview will also help you use this powerful modifier for generating other procedural information which can be used down the hair pipeline.
