I have 2 objects that are driven identically for the nodes that are involved with pumping out the material. The image on the left is the Material Preview. The image on the right is the Render

The icosphere rainbow is a single object and is rendering correctly.

The projected donut/whisk looking object is a result of curves on points. I can tell that I've captured the surface points correctly because when I allow the gradient to cover the entire object, the gradient stretches on the longer stalks in the back. When doing it naively, the gradient follows the "water level."

Here is the geo-nodes for the broken one

Here is the geo-nodes for the sphere

They have identical materials.

Does this answer your question? Black artifacts when looking through many transparent objects? Hard to tell from just the screenshots, so maybe this is caused by too few bounces. – Gordon Brinkmann Nov 07 '22 at 08:01

Yes, yes, yes!! Thank you @GordonBrinkmann! – Gabe E. Nydick Nov 07 '22 at 08:04
Now that it works, I need a render farm to deal with it :( – Gabe E. Nydick Nov 07 '22 at 08:08
Well, sorry - this is not the place for suggestions of this kind ;) – Gordon Brinkmann Nov 07 '22 at 08:13
