1. This tutorial is incorrect and will not create correct models. This has nothing to do with paracloud, but with the conversion of a heightfield image to a rgb greyscale image. If it were as easy as this you could use the generated greyscale image as a displacement driver in any sophisticated 3d application then freeze the displaced geo. but you cannot do so as a multicoloured heightfield map once converted will not generate the deep blues as a low point. In the tutorial shows, it is shown as a high point in the resulting geometry.

2. We skipped a few processes - and will add it to the tutorial. If you use each color channel seperately you can create 3 heightfield images (for R,G and B channels) and then drive it based on each channel separately.
