Hey all!
I have both real plume and waterfall installed (I kept real plume because it has cool looking srb plumes) and for the "Thud", "Twitch", "Spider", and "Ant" engines the plumes have overlapped. I don't think any other ones are like this but I get a performance hit because of it and they don't look good together. I have the latest update for realplume so I'm not sure what the problem is.
Thanks
