I can use A to select all, and the Select Random tool works as well. But, RMB and border select do nothing… I think select linked does nothing either but I’m not sure how to use that one.
I just upgraded to Blender 2.78 in hopes it would fix it, but it did not. I also uninstalled the add-ons I had.
Am I missing something obvious?
Also, I can’t figure out how to get the dots between the segment sections to display as seen in the images on this page https://www.blender.org/manual/physics/particles/mode.html
And finally, when I render, the children seem to change shape. After a Cycles render, the hair in the display looks different than it did before. If I enter particle edit, it jumps back to the way it was. That is not as important for me to solve as the above issues.
On the right, the way it looks before rendering, or after snapping back after entering particle edit mode. On the left, how it appears in the viewport after rendering in Cycles (also looks this way in the render).
