1. First bug is about exporting parameters in Randomize node:
I add a "Randomize" node in style editor, then I link some segments to it, and then I want to export parameters (to control percentage of segment types from Parameters rollout), but my newly added segments are not in export list, and I can't export their "Presence" parameter. To do so, I need to close and reopen Style Editor, then they appear in export list.
2. Second, and much more serous bug is that when I link Numeric node to "Presence" parameter of "Randomize" node, it does not control anything, seems like it is simply ignored.
I Attach a simple scene which demonstrates this bug. In RailClone object there are two generators: one with "Randomize" node, where everything is in a correct logical way but not working, and the second generator with a workaround I had to do, just in case...
