Thank you, tamte. Both of your suggestions work like charms.

I'm glad that I learned a new trick from you.

The geometry has an attribute “id” which contains string values for each polygon.

How shall I refer to it in the “filter by expression” option in the delete node?

I tried the following, and they didn't seem to work:

I want to export some geometries with color as obj file and import them in Rhinoceros3D software.

The color information is already embedded as attributes on point and vertice levels, as shown below?



However, only geometry information is exported in obj file, and therefore, I'm unable to see colored surfaces when import it in Rhino, as shown below.



May I ask if there is a way to export geometry in Houdini with surface color information embedded?

And if there is, which file format I shall use for export?

Thanks.
