I don't have a capture card, but this is essentially how to do it, for more precision with where it ends up simply put a little guide around it. Good luck! CLICK
I don't really see the point. Why would you want to make sender nodes hard to notice and indistinguishable from receiver nodes? You can shoot through and easily see through the green energy thing, so why bother merging it?
I suppose you could use it for maze maps...or to confuse n00bs into thinking you were a hAxz0r...but thats all i can see :S
I have seen it done, and it was actually cool. I saves space, and if you merge it into the pipeline in the center of Foundry, it shoots you up. I think it was right-side up, though. ANd this is much more useful than you would realize. It saves space and is great for mazes.
mainly for aesthetics, a lot of people don't like seeing those pesky green yellow (colorblind) thingy's, messes up the colors. The only "problem" with it for me is that yo uhave no idea its their. I don't know, i'm sure someone will come up with a great use of it. Its never bad to learn things anyway.
that dude took foreeeeeeeeeeeever to do that, 3 minutes, i mean the least he could have done was sped that up a little...neways, i guess that was somewhat helpful, i don't really like that green crap being visible...
So he's done the door technique, a slow way. I dont see this as being pointless. It wont do much but it could develop some interesting concepts in future maps.
