Texture Reference Object with alembic procedural

[hollov]

Hi all,

I'd like to know what is the suggested way to use Texture Reference Object with alembic procedural.

I've tried to achieve this using operators based on the docs about how to override shaders on polymeshes under an alembic procedural.
I'm trying to create the "Pref" parameter using aiSetParameter with assignment expression:

vector[] Pref=[[1.13375068 2.29986978 -0.797210693] [0.99171114 2.29986978 -1.07597911] [0.770479202 2.29986978 -1.29721105] ...]

But it's not working. Is it even possible to declare "Pref" with operators?
Or can you suggest another way?

Thx,
hollov
