So something related to this…
My attributes define some traits, that can then be used by another custom OTL node at any point in the node tree, to modify the transform. In the OTL I use a primitive pattern to check for the attributes before doing the necessary work… but I'm using the VEX expression in the primitive pattern parameter:
`chs("../parentotlparm")` & { usd_isattrib(0, @primpath, "myattrib") }
.
It's REALLY slow. Would a schema allow me to speed this up in some way, or is there an easy way to speed this up? The tree I'm working with now is only about 9 primitives, but the performance hit is BY far the largest cook time in the node graph.
Cheers,
Jon
