Hi,

There is a “Geometry file” option in Primitive Attribute Vop . But it can only use external .bgeo file. I want query primitive attribute for input geometry. How to do?

Thanks!

op:`opinputpath(“.”, 0)

where 0 is your input geometry input number whose primitive attribute you want to query.
If it's in second input then change to 1.

Import Attribute vop imports specific attribute from entire geometry. You can't specify particular primitive number there.

Note: result of example file can be easily achieved using pointcloudopen vop but I want to show primitive attribute one what @jerry7 asked for.
