Alembic Mantra Stylesheet

[up4]

Hello,

 

I'm trying out JSON stylesheets with Alembic archives. I have a mantra surface at "/shop/mantrasurface" and an Alembic archive at "/obj/alembicarchive" in my HIP. When I look at the Alembic file with "abcecho", I get two objects "/geo1" (the geo node from the original HIP) and "/geo1/merge1" (the merge SOP within the geo node)

{
    "styles" : [
        {
            "target" : { "name" : "geo1"},
            "overrides" : { 
                "material" : { "name" : "op:/shop/mantrasurface" },
                "materialParameters" : {
			"baseColor" : [0.5, 0, 0]
		}
            }
        }
    ]
}

Replacing "geo1" with "merge1" or "geo1/merge1", with or without a root "/" won't work. Trying many hypothetical syntax and nomenclatures for the "material" "name" didn't fix it.

 

Trying it either at object level (with the "Material Style Sheet parameter") or with the -S mantra argument won't work and won't give me any error message even at the highest verbose level so I don't even know which part is not working.

 

How can I generate the simplest style sheet based on the information I get with "abcecho"? And how can I debug a style sheet efficiently?

 

Thanks!

Also, is there/what is the equivalent of the Mantra -S flag on the mantra and hqueue ROPs? Thanks!
