Sorry to revive an old thread, but I’m currently experimenting with baking hair via Arnold too. I do find the bake results to be much better compared to xNormal, but I’m a little bit stuck with a few things and have a few questions. It’s great that Arnold allows you to bake the raw data for the hair, rather than turning it…
you dont need to use RTT - i found it convenient because it allowed me to bake to a known area without having to argue with cameras. just simple renders should work fine. I seem to remember it being possible to dump each relevant channel out to it's own AOV but my memory of this is very fuzzy now. Arnold will allow you to…
You'll get better results if you bake hair from hair data than if it's converted to geometry - most hair rendering setups use tricks to avoid exactly what you're getting here. You also don't have to deal with massive high res meshes that take ages to export and render. Assuming you're using maya/Xgen... Arnold does a great…
