Can i get the render layer from a ASS file ?

[guillaume_roeder]

hi !

Does anybody know how to get the render layer from a ass file ?

I've tried using the arnold api, but i could'nt find a way ... when i open the ass file, i can see the render layer in the "options" struct, and i successfully listed all the paramters in the options node using the node entry api from anrold, but there are no render_layers in the list...

plz help !

An ASS file is basically a baked version of whatever the current render layer was in Maya.
Arnold itself has no concept of "render layers".

MtoA adds some user data to the options node, to tell you what render layer was baked to the ASS file.

I see.

Is there a way to get those user data ?

And thank you by the way.

Ignore my previous question i found the user data API 🙂 !

thank you !

My bad... user data api doesn't work.
So i go back to my previous question:

Is there a way to get the user data ?

Are you sure you are getting the options node from the right universe?

I succeeded in getting the UserParameterEntry, now i juste need to find a way to get ne name of the layer.

Thank you 🙂
