I can't seem to get obsidian pipes working. I Googled and couldn't find anything of use, and nothing to suggest anyone else was having the same problems I was, which leads me to believe it's not a problem with the mod.
Here I have a stone transport pipe set up with an obisidan transport pipe in the middle. In the first screenshot, items have been dropped on an unpowered obsidian pipe and haven't been collected. In the second screenshot, items have been dropped on a powered obsidian pipe and haven't been collected.
What am I doing wrong?
EDIT: Sorry, fixed it right after posting. The problem was having the pipe connected on both ends.
