New user of World Machine here. I have a raw file height map and I want to apply terracing to a specific part for which I have a bitmap mask (saved as PNG - one with Alpha, one without). I bring in the mask through a file input node, set the size, tick interpret as RGB. On the node I set the display hint to Mask. All I have is 2 File inputs, an erosion generator, and a file output. I can see the mask (white for the area I want to terrace), it is in the right position. I plug the file input heightmap node into the erosion mask node, and generate. but the erosion is applied to the whole image.
I feel the steps I have taken are pretty logical, I followed the tutorial although that didn’t deal with bitmap masks.
Can anyone tell me what I’m doing wrong?
