Can you please explain a bit more on the Custom Attributes usage when Paged Geo enabled in the Octane Object Properties? How do you use it in general?
Certainly!
The following example will take the Cd and P position attribute to drive color and then another noise for a mask which will be used just for transparency.
1) Create your SOP network and add the required Attributes you want to use in your material, ensure it is packed and instanced.
2) Create your material and add some 'Texture Instance Color' nodes that will be used to assign the attributes to. (Note you do not need to select a file or anything, at this point it is merely a "bridge" for the data)
3) Enable "Packed Geo Instancing" on the Object's Octane Properties and Assign your Custom Attributes to the appropriate "Texture Instance Color" Nodes. (It helps to name your "Texture Instance Color" nodes)
Example:
SOP
Setup Material (Add 'Texture Instance Color' Nodes)
Assign Attributes
Output
Hope the brief overview helps!
