It would be really useful to have the option to bake out tangent-space normals as well as object-space in the normal map maker.
I did a search and found some similar topics dating back 2008 & 2011 on this.
I've spent more hours than I'd like figuring out how to use xnormal with a non-compressed high detail mesh & compressed lower-detail mesh output from world machine to make my own tangent-space normal map. And this is something I'm going to have to do every-time I update the terrain.
Any chance of getting this feature? It would be great to finally have it.
