I'm trying to create procedural rock generator and during tests with creating normal map from hipoly version to lowpoly I hit a wall.

Gernerator creates UVs for lowpoly version:


Added baketexture node in Out Networks, and after setting UV Object1 to lowres version of generator, and HighRes Object1 to hires I got (black/white image without any details for all output formats, tangent-pace notmal, displacement, occlusion, cavity, etc):


I tried also use scaled up version of lowpoly geometry to use as UV Cage Obejct1 with exactly same result.

What am I doing wrong? I could use xnormal after exporting both geometries to obj files but as Houdini allows that approach it could be nice to have this all-in-one place, generator will be used to create different variants of rocks as game assets.

Thanks for help… I figured out it myself, it may be worth for someone in future: it was enabled by default Disable Lighting/Emission (undocumented option as I see).
I must say, Your docs are crap SideFX - hope you'll fix that soon

It's the first property if you search for “Baking Properties”. We'll see about updating the Mantra User Guide.

The help page for the bake texture render node could use a refresh. Not very many of the default properties are mentioned, and some tabs are completely omitted.
