Trouble accessing vertex colors 2022.1_27.1 (3.4.1)

Hi
Looking forward to using the newest release soon. Right now I can't access the vertex colors on a mesh using the octane attribute nodes (Col, Col.001).
Wiring it directly using the octane Node view doesn't work either. Using Cycles, it works, the vertex colors show.
in the previous 2022.1_27.5_beta (3.3) it worked too.
Thanks for any hints!

I tried rendering vertex colors in the latest version (Blender_Octane_Edition_2022.1_27.15_stable.exe)
Is it fixed already, maybe I did something wrong? Here's what I did:
Using cycles, the colors are coming through:

Try to convert the domain from Face Corner to Vertex, you can do that from the drop-down arrow in the Color Attributes tab.

Thanks opstyix, that did help! It never occured to me that it might be because of that.
Now I just have to find out how to do that using python.
Maybe face corner color attributes will be supported again some day.

in case someone needs it here's the code used to convert the vertex color storage type:
Code: Select all
for o in bpy.context.scene.objects:
bpy.context.view_layer.objects.active = o
try:
o.data.vertex_colors.active = o.data.vertex_colors["Col"]
bpy.ops.geometry.color_attribute_convert(domain='POINT', data_type='BYTE_COLOR')
o.data.vertex_colors.active = o.data.vertex_colors["Col.001"]
bpy.ops.geometry.color_attribute_convert(domain='POINT', data_type='BYTE_COLOR')
except:
print(f"trouble converting vertex colors for {o.name}")
