How could I tell octane to what object it should bake ? I mean I want to bake several hi-poly objects with displacement to low poly shell . I see baking camera , and Revert baking does the trick sometimes . Still It chose wrong object to bake on

What's baking group id and uv set for?

Hi kirk,

You may arrange your geometry by assigning baking group IDs to various subsets, which can be found in the object layer node, this is equivalent to how render layers work.

The UV set parameter is used to select the UV map you want to use for the baked output, in case your mesh contains more than one. This can be used for instance if one set if used for texture mapping and another one for baking.

You may find all information about the baking system here:

Please let me know if you need any more help.

To be honest I have same question for render layers. How can I set/ point to an imported object in Octane to be on certain render layer? And within certain baking group?

Upon the link you provided I didn't find any usefull info for both questions. For render layers it has few pictures from current Max probably. Not form my pretty old version of 3d max although. I have Blender Octane plugin and can't find any info how to set it there or in Octane directly.

For baking ID the link have just a short paragraph not explaining anything really. Beside there's a picture showing " Baking render target" I can't find such a node in Octane 3.02

Would be much appreciated if you could explain step by step how baking ID could be set in Octane. I mean Octane standalone. With imported scene as orbx file.

PS. Have actually figured it out how to set Render layers in Blender. Still no clue how it's related with baking ID. Can't find anything that could set a specific baking Id neither in Octane directly or Blender plugin. Octane seemingly does bake from one object (hi poly) to another low poly one , Just always on wrong object.


I have to say I completely lost with this new baking capabilities. And I even don't mention I usually need a "cage" object to set specific projection/ray tracing direction. Guess there is no such option at all.

Can Octane even be used for baking displacement/normal maps? I thought it was only for lightmapping (which I tried and it works beautifully).

From what I tried so far it looks like Octane can bake Z depth/height map and object space normals, sometimes you need to set "revert" baking. It perfectly see other , hi poly object projected to low poly one through normals direction. So I guess it should.

Although looks like it can't do tangent space normals but it's not that important since they are never right and every soft do them differently . Usually you just convert object space into tangent one, specific for a game engine.

Only problem it works when you have only two objects and only one having UV s.


ps. Only lightmapping. Who would need it nowadays? We stopped to use actual lightmaps decade ago.
