Vertex color node equivalent in Houdini? (coming from maya / blender)

Recommended Posts

TLDR Version:

I'm trying to render an fbx in houdini, and the objects are colored using vertex colors. In maya, we do `mesh display > Toggle Display Colors attribute`.

Is there a similar way to do this in Houdini?

 

Longer Version

All the models I am working with use Vertex Colors as their color/diffuse base, and sometimes use vertex alpha for transparency.

For Blender, I know you need to create a material using the Vertex Color Node.

If using the .fbx in Maya, you may need to refresh the Vertex Color display to view them. to do so, you select the top-level group in the Outliner, then select Polygons -> Colors -> Paint Vertex Color tool. Simply activating this tool once will show the vertex colors.

You can also select “Toggle Display Colors Attribute”.

from autodesk documentation: "Turning on the Display Colors attribute lets you view the color per vertex information as well as any assigned shaders on a polygonal mesh when the display is set to shaded mode. The default Display colors setting for any object is off until color per vertex information is applied"

Is there a similar option / method of viewing vertex colors in Houdini?

I'm attaching a .blend file with the vertex colors showing, as I desire them to in houdini.

I'm also attaching the fbx file with the geo/ vertex color info I am using.

It might be overwritten by the shader? If I delete the Material Network generated when I import the FBX through the File menu, I see colors. If I import the FBX through the file node, it doesn't create that default material network at all and I can also see (seemingly appropriate) colors.

It looks like all the color information is in the FBX file.

The Cd attribute is assigned to the vertex context.
