I set all vertices to pure white then hit dirty vertex colors. All verticies paint completely black except a tiny bit of white that you can barely at the base of the branches. It doesn't look like its doing much of a concavity calculation to me. The crevice between the main trunk branches is the same black as everything else. Any ideas?
Thank you for a quick response, but no luck so far. Turning off normalize changes the black to a medium gray, but the pattern is the same. In particular the lack of any variation in the cracks between the main trunk branches makes it really blah.
That is so dependent on geometry that is hard for the same trick to work exactly alike. I guess you could exaggerate the effect when later in the lesson Kent uses some nodes to achieve just that with a color ramp. Try that if it doesn't work, then you can upload your file to Dropbox or Google Drive for us to take a closer look at the issue.
You know what.... I apparently missed the step in the very first video where he put the jagged crease in the trunk. Instead I had some base branches, which he actually did *not* have.
I guess the lesson here is that, A) you should make sure you followed all the steps, and B) apparently dirty paint doesn't register close together loose parts as a cavity. It only recognizes cavities in a contiguous mesh.
