To transform or not to transform?

[Dune]

Who can make sense of this behaviour of the transform shader? The whole terrain shifts upward or not (see preview), depending on whether the transform shader is attached without any function, taken out, or active without any change applied. Very strange. Is it a bug? I though I knew TG by now....

Hi Ulco,

The "shader" input is only called if the Transform Merge Shader is enabled. If it's disabled, it will simply act as a pass-through for the main input (just like every shader in Terragen). The shaders that you want to transform are not connected through the main input (nor should they be with this shader), so there's nothing to pass through.

Perhaps you should be using the Transform Input Shader instead? Then you can enable/disable it to enable/disable the transform effect.

Ah, thanks Matt. That makes sense. I don't know why I took this transform merge shader, probably as it was sitting somewhere unused. Thanks again!
