Title: Vertex Color via deformable animated alembic file exported from maya
Post by: Masoud Zangi on May 12, 2020, 04:02:51 AM
I wanna use MASH toolkit from maya to create motion graphics and render it KS. I exported a sample scene for testing purposes. Since I've used color node In MASH to create random colors on cubes , I chose option to export Vertex Color with my alembic , And it worked in maya , But when I import it into KS and use "Vertex Color" node in material graph I see NOTHING but black color. I searched a lot but I can't find a solution. Any Ideas folks?
I will attach all necessary assets for testing

It looks like KS can't see vector colors from some special Alembic formats. It happens with Alembic export from Blender 3D too. I would suggest to send this files to Luxion Support and open a case, so they can have a look on them.

Try this... i can get it working in C4D but i had to re bake and change the points mode

I have never used Maya so not sure how to fix in that app.

It has something to do with Points Only or Poly Points

Cheers

Thanks alot.. seems your's working. Can you please explain how you fixed my alembic in c4d so I can do it as a workaround in my motion graphic pipeline?

No problem, what version do you have, requires R20

1. Load your .abc file into C4D , select it and press 'c' to make editable.
2. C4D will add an Alembic tag to your file
3. Select the Vertex Color tag and change the Vertex Colors from 'Polygon Points' to  'Points Only'

Export

That's it.
