Vertex color

[GimbalLocked]

Hi,

I'm trying to find out how to use Octane Vertex Attribute to make a vertex painted sculpt from 3D Coat render in LW Octane, without having to go through retopo and UV mapping.

I save out the vertex painted sculpt as FBX, load it into LW, attach Octane Vertex Attribute node the surface material Albedo. Nothing happens. So I guess that's not the way to do it Can't find any documentation to guide me here.

I've just replied a question like that here: viewtopic.php?f=36&t=73150&start=41

Thank you - I used the Object Properties to extract the name for the map as described, and as you can see on my attached image. Something's strange though, since the ball turns up black except for a few triangles with bright color.
I have attached screenshot of how it looks when loaded into 3d Coat for vertex paint.

Any idea why it turns out the other way in LW Octane?

Nope, sorry, can you please share this scene to take a look at it here?

Thanks,

Thank you - I've attached my test scene (it will be missing an HDRI for lighting).

It also includes the original FBX sphere.

Hmm, but this object doesn't have any color vertex map! Have you been able to render the vertex color map using the LW native engine?

Thanks,

Hi Juanjo, (sorry I've been away) - it does have vertex color, at least the FBX does on import. The one I also included in the demo scene. When I import that into f.ex. 3DCoat, it shows all the vertex color normally.

Yes, but LightWave seems to don't import this vertex color. Can you see it in the Modeler vertex list window?

Thanks,

No, it's not there. Then I guess it's not an Octane problem - thank you for your time.
