Why is this? I know that redirect shaders 'redirect' the input along any axis but what does that mean exactly?
QuoteSecondly, I know that the Merge Shader when left to default settings is set to 'Mix' displacement. I take it this means that the mean altitude of both inputs is used as the output. But what if one of the inputs has two altitudes at one point (ie, has overhangs)? Does it simply take the mean of all altitudes at a given set of 2D coordinates?I appreciate any answers.

Thanks again.If I might make a suggestion - these explanations would significantly improve the node reference guide you have on your website. The current explanations for the redirect and warp shaders ("The Warp Shader warps one shader by the input of another." and "The Redirect Shader allows you to "redirect" the effect of the input shader along a specific axis.") are pretty much just stating the obvious and aren't too helpful.
