No attributes in alembic

Recommended Posts

When I have rendered an Alembic and import the .abc in through an Alembic node I am unable to read out any attributes from it. It is a particle simulation with color attribute. The colors show in the viewport but right-clicking on the alembic node shows no point attributes.

Need to access the Cd to remap the colors. Any ideas?

 

TIA

Don't right click, middle-click. That is how you inspect what attributes are on a node. A big black box with information should appear. Also try selecting the geometry then view the geometry spreadsheet. Perhaps the color information is not in the right column. (i.e. on vertex instead of points...?)

Sorry, meant middle-click. I use a wacom and thought i was using right-click. 

Will check the spreadsheet! Thanks!

Alembic files are by default packed geometry. To access their attributes, you can unpack the geometry first.

Sweet, great link!

Thanks guys.

My primary 3d package is C4D and i usually do my rendering there. However lately i have had problems importing alembic files into c4d. I cant transfer over the attributes from houdini to c4d and I get frequent crashes. This might have shed some light over that issue as well. The 3 primitive attributes that I can see on the alembic before running it through unpack node is the same jibberish attributes i get from the alembic when imported in c4d. Guess there is an issue with the alembic importer in c4d where it does not unpack the alembic and therefore cant read the attributes. Just a thought.

As this is not a c4d forum I certainly do not expect any solution to that. But feel free to comment on it if you have any information/thoughts. 

Cheers
