Hi,

Can you point me out on how to grab the Cd attrib on octane scatter? Or that is not possible?

Hi thanulee,

I will double-check tomorrow, but as far as I know, the Cd attribute isn't supported using the Octane Scatter.

What you can do for the moment is get the Cd attribute information on Packed geo instancing - a 'Texture Instance Color' in the material pointing to the "rgb4k_map.ppm" or alpha with "alpha4k_map.ppm". SOP obj Octane properties "Instance ID's from" needs to be set to Packed RGBA values from Çd' point attribute.

If you don't need it packed, then you can use the 'color vertex attribute' with Cd. Just don't forget to add the attribute on the SOP object under Octane / Attributes / Point Vector Attrs.
