Hello, this forum looks like a great place to learn. I'm having trouble using color value to drive density region with scatter node when fracturing. It was possible, from my current knowledge of this software, to use the old scatter node to drive fracturing based on color on a mesh, but now this feature seems to be gone, correct me if I'm wrong? Thank you.

The feature is not gone, the new scatter node implements this as a density attribute. Simply enable the Density Attribute checkbox and then type Cd(attribute name for color) instead of the default density. Note, just like the previous version of scatter, Cd must exists upstream before you reference it.
