MacOS: Material Browser slowing Sketchup down

Hi guys,

I am having trouble with a couple of models that rely on VRAY materials for accurate rendering. Every time I am trying to paint something with the bucket tool and the material browser opens up Sketchup goes to an absolute crawl. We are talking 30 seconds and more before it responds again. As soon as I close the Material-Browers window everything is good again.

Found this old post: Materials palette/paint tool freezing in 2017

Might that be the issue or had this been fixed and I am barking up the wrong tree?

It’s insane. I am ALMOST DONE WITH THIS FILE and now I will spend hours repainting the last couple of items because of a customer request. Something that would take 5 minutes the most if this thing would work…
