Being that, unless I am mistaken, Copernicus doesn't really manage it's maps/channels in the same way that Substance Painter does, in terms of painting directly to certain channels, etc - it's likely that no, it won't paint to PBR channels in the same way. Instead, it'll be up to you to determine how you use the paint feature to refine the maps you have and then use the data to create the maps.

I wouldn't be surprised if there are some recipes and examples that could be tweaked. H22 seems quite recipe friendly.

I ran into this problem.

The solution I actually ended up using was a Claude MCP to Houdini and getting it to resolve it for me.

The actual issue is the material attribute vs name attribute and how that gets pulled into Solaris. What you need to do is look at the attribute that is responsible for separating out the collection into its various components on the SOPs side.

Then, when you import into Solaris, you need to ensure that this attribute is properly carried over. I can't remember clearly what this is.

I Believe you need to transfer the material attribute to the name attribute on SOPs side, then ensure the name attribute is brought over to Solaris.

You can copy/paste the material library from SOPs into Solaris Material Library and then you need to assign each material name to its mesh component.

There are a few tools out there you can get for free that will do this for you.

This is something I've been hoping for...definitely helps. Please let me know if you want anyone to help test it!
