Tangent Space Normal Maps

Hey there, not a whole lot to report on since the last blog entry, just been workin’ away! I’ve been exploring VOPs (building shaders in Houdini) a lot recently and am starting to get somewhere with it I believe. On that note, I noticed a few questions on various forums recently regarding how to implement Normal Maps from ZBrush in Houdini and so decided to tackle the issue. With Mark Elendt’s and Andrew Clinton’s (two of Side Effects Software Inc’s developers) I was able to provide the Houdini Exchange with a simple example of how to use normal maps (both Object and Tangent Space maps) in a material.
